of the following words as constants, class names, function or method names.
Using them as variable names is generally OK, but could lead to confusion.

Various parts of the PHP language are represented internally by tokens.
A code snippet that contains an invalid sequence of tokens may lead to errors like

This means that the concrete value of a token may change between two PHP

This means that your code should never rely directly
on the original T_* values taken from PHP version X.Y.Z, to provide some compatibility
across multiple PHP versions. Instead your code should utilize custom values

will work with both PHP versions and T_* values.

The position in which you place the <literal>.PHP</literal> will

<screen>
<![CDATA[

There is a small problem if you intend to use this technique and use your
PHP scripts as a command line filter, like the example below:

]]>
</screen>
or
<screen>
<![CDATA[
dir | script -arg1 -arg2 -arg3

</screen>
You may find that the script simply hangs and nothing is output.
To get this operational, you need to make another registry change.

PHP 5.5+ require at least Windows 2008/Vista, or 2008r2, 2012, 2012r2, 2016 or 7, 8, 8.1, 10. Either 32-Bit or 64-bit (aka X86 or X64. PHP does not run on Windows RT/WOA/ARM).
As of PHP 7.2.0 Windows 2008 and Vista are no longer supported.
</para>
<para>
PHP requires the Visual C runtime(CRT). Many applications require that so it may already be installed.
</para>
<para>
PHP 5.5 and 5.6 require VC CRT 11 (Visual Studio 2012). See: <link xlink:href="https://www.microsoft.com/en-us/download/details.aspx?id=30679">https://www.microsoft.com/en-us/download/details.aspx?id=30679</link>

<para>
PHP 7.0 and 7.1 require VC CRT 14 (Visual Studio 2015).
PHP 7.2, 7.3 and 7.4 require VC CRT 15 (Visual Studio 2017).
The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable
for all these PHP versions, see
<link xlink:href="https://visualstudio.microsoft.com/downloads/">https://visualstudio.microsoft.com/downloads/</link>.
</para>
<para>
You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds.
</para>
<para>
If CRT is already installed, the installer will tell you that and not change anything.
</para>
<para>
The CRT installer supports the /quiet and /norestart command-line switches, so you can script running it.
</para>
<para>
VC11 CRT DLLs can be copied from your local machine to a remote machine(a `Copy Deployment` installation) instead of running the installer on the remote machine (such as a web server you have restricted access to).
</para>
<para>
VC14 CRT does not support a `Copy Deployment` installation. VC14 CRT has many more DLLs(most in files with names starting with api-*). If you can find them all and copy them, it will also work (try a tool like Resource Hacker to get a list of all the DLLs to copy).

There are two ways to set up PHP to work with Apache 1.3.x
on Windows. One is to use the CGI binary (<filename>php.exe</filename>
for PHP 4 and <filename>php-cgi.exe</filename> for PHP 5),
the other is to use the Apache Module DLL. In either case
you need to edit your &httpd.conf; to configure Apache to
work with PHP, and then restart the server.
</simpara>
<simpara>
It is worth noting here that now the SAPI module has been
made more stable under Windows, we recommend it's use above
the CGI binary, since it is more transparent and secure.
</simpara>
<simpara>
Although there can be a few variations of configuring PHP
under Apache, these are simple enough to be used by the
newcomer. Please consult the Apache Documentation for further
configuration directives.
</simpara>
<simpara>
After changing the configuration file, remember to restart the server, for
example, <command>NET STOP APACHE</command> followed by
<command>NET START APACHE</command>, if you run Apache as a Windows
Service, or use your regular shortcuts.
</simpara>
&note.apache.slashes;
<sect3 xml:id="install.windows.legacy.apache1.module">

You should add the following lines to your Apache &httpd.conf; file:

<simpara>
If you would like to present PHP source files syntax highlighted, there
is no such convenient option as with the module version of PHP.
If you chose to configure Apache to use PHP as a CGI binary, you
will need to use the <function>highlight_file</function> function. To
do this simply create a PHP script file and add this code:
<literal>&lt;?php highlight_file('some_php_script.php'); ?&gt;</literal>.

Apache 2.x is designed to run on the Windows version designated as

The position in which you place the <literal>.PHP</literal> will
determine which script or program is executed when there are matching

There is a small problem if you intend to use this technique and use your
PHP scripts as a command line filter, like the example below:

</screen>
or
<screen>
<![CDATA[

You may find that the script simply hangs and nothing is output.
To get this operational, you need to make another registry change.

<title>Installation of extensions on Windows</title>
<para>
After installing PHP and a web server on Windows, you will probably want to
install some extensions for added functionality. You can choose which
extensions you would like to load when PHP starts by modifying your
&php.ini;. You can also load a module dynamically in your script using
<function>dl</function>.
</para>
<para>
The DLLs for PHP extensions are prefixed with <literal>php_</literal>.
</para>
<para>
Many extensions are <emphasis>built into</emphasis> the Windows version
of PHP. This means additional DLL files, and the
<link linkend="ini.extension">extension</link> directive, are
<emphasis>not</emphasis> used to load these extensions. The Windows
<link linkend ="install.windows.legacy.extensions.overview">PHP Extensions</link>
table lists extensions that require, or used to require, additional PHP
DLL files. Here's a list of built in extensions (updated PHP 5.0.4):
<link linkend="book.bc">BCMath</link>,
<link linkend="book.calendar">Calendar</link>,
<link linkend="book.com">COM</link>,
<link linkend="book.ctype">Ctype</link>,
<link linkend="book.dom">DOM</link>,
<link linkend="book.ftp">FTP</link>,
<link linkend="book.libxml">LibXML</link>,
<link linkend="book.iconv">Iconv</link>,

<link linkend="book.wddx">WDDX</link>,
<link linkend="book.xml">XML</link>&listendand;
<link linkend="book.zlib">Zlib</link>.
</para>
<para>
The default location PHP searches for extensions is
<filename class="directory">C:\php5</filename>. To change this
setting to reflect your setup of PHP edit your &php.ini; file:
<itemizedlist>
<listitem>
<para>
You will need to change the
<link linkend ="ini.extension-dir">extension_dir</link> setting to
point to the directory where your extensions lives, or where you have
placed your <filename>php_*.dll</filename> files. For example:
<informalexample>
<programlisting role="ini">
<![CDATA[
extension_dir = C:\php\extensions
]]>
</programlisting>
</informalexample>
</para>
</listitem>
<listitem>
<para>
Enable the extension(s) in &php.ini; you want to use by uncommenting the
<literal>extension=php_*.dll</literal> lines in &php.ini;. This is done
by deleting the leading ; from the extension you want to load.
<example>
<title>Enable <link linkend="book.bzip2">Bzip2</link> extension for PHP-Windows</title>
<programlisting role="ini">
<![CDATA[
// change the following line from ...
;extension=php_bz2.dll
// ... to
extension=php_bz2.dll
]]>
</programlisting>
</example>
</para>
</listitem>
<listitem>
<para>
Some of the extensions need extra DLLs to work. Couple of them can be
found in the distribution package, in the main folder, but some, for example Oracle
(<filename>php_oci8.dll</filename>) require DLLs which are not bundled
with the distribution package. Don't forget to include <filename
class="directory">C:\php</filename> in the system
<envar>PATH</envar> (this process is explained in a separate <link
linkend="faq.installation.addtopath">FAQ entry</link>).
</para>
</listitem>
<listitem>
<para>
Some of these DLLs are not bundled with the PHP distribution. See each
extensions documentation page for details. Also, read the manual
section titled <link linkend="install.pecl">Installation of PECL
extensions</link> for details on <acronym>PECL</acronym>. An
increasingly large number of PHP extensions are found in
<acronym>PECL</acronym>, and these extensions require a
<link linkend="install.pecl.downloads">separate download</link>.

</para>
<para>
This command will create an IIS script mapping for *.php file extension, which will result in all URLs
that end with .php being handled by FastCGI extension. Also, it will configure FastCGI extension to
use the executable <filename>php-cgi.exe</filename> to process the PHP requests.
<note>
<para>
At this point the required installation and configuration steps are completed. The remaining
instructions below are optional but highly recommended for achieving optimal functionality
and performance of PHP on IIS.

<sect3 xml:id="install.windows.legacy.iis6.impersonation">
<title>Impersonation and file system access</title>
<para>
It is recommended to enable FastCGI impersonation in PHP when using IIS. This
is controlled by the <varname>fastcgi.impersonate</varname> directive in <filename>php.ini</filename> file. When
impersonation is enabled, PHP will perform all the file system operations on
behalf of the user account that has been determined by IIS authentication. This
ensures that even if the same PHP process is shared across different IIS web
sites, the PHP scripts in those web sites will not be able to access each
others&#39; files as long as different user accounts are used for IIS authentication
on each web site.
</para>
<para>
For example IIS 5.1 and IIS 6.0, in its default configuration, has anonymous authentication enabled
with built-in user account IUSR_&lt;MACHINE_NAME&gt; used as a default identity. This means that in
order for IIS to execute PHP scripts, it is necessary to grant IUSR_&lt;MACHINE_NAME&gt; account
read permission on those scripts. If PHP applications need to perform write operations on certain
files or write files into some folders then IUSR_&lt;MACHINE_NAME&gt; account should have write permission to those.
</para>
<para>
To determine which user account is used by IIS anonymous authentication, follow these steps:
<procedure>
<step>
<simpara>In the Windows Start Menu choose &quot;Run:&quot;, type &quot;inetmgr&quot; and click &quot;Ok&quot;;</simpara>
</step>
<step>
<simpara>Expand the list of web sites under the &quot;Web Sites&quot; node in the tree view, right-click on a web
site that is being used and select &quot;Properties&quot;;
</simpara>
</step>
<step>
<simpara>Click the &quot;Directory Security&quot; tab;</simpara>
</step>
<step>
<simpara>Take note of a &quot;User name:&quot; field in the &quot;Authentication Methods&quot; dialog</simpara>

Configure IIS FastCGI extension settings for recycling of PHP processes by using the commands shown below.
The FastCGI setting <varname>instanceMaxRequests</varname> controls how many requests will be processed by a single
<filename>php-cgi.exe</filename> process before FastCGI extension shuts it down. The PHP environment variable
<varname>PHP_FCGI_MAX_REQUESTS</varname> controls how many requests a single <filename>php-cgi.exe</filename> process
will handle before it recycles itself. Make sure that the value specified for FastCGI <varname>InstanceMaxRequests</varname>

<sect3 xml:id="install.windows.legacy.iis7.impersonation">
<title>Impersonation and file system access</title>
<para>
It is recommended to enable FastCGI impersonation in PHP when using IIS. This
is controlled by the <varname>fastcgi.impersonate</varname> directive in <filename>php.ini</filename>
file. When impersonation is enabled, PHP will perform all the file system operations on behalf of
the user account that has been determined by IIS authentication. This ensures that even if the
same PHP process is shared across different IIS web sites, the PHP scripts in those web sites
will not be able to access each other&#39;s files as long as different user accounts are used
for IIS authentication on each web site.
</para>
<para>
For example IIS 7, in its default configuration, has anonymous authentication enabled with
built-in user account IUSR used as a default identity. This means that in order for IIS to
execute PHP scripts, it is necessary to grant IUSR account read permission on those scripts.
If PHP applications need to perform write operations on certain files or write files into some
folders then IUSR account should have write permission to those.
</para>
<para>
To determine what user account is used as an anonymous identity in IIS 7 use the following command.
Replace the &quot;Default Web Site&quot; with the name of IIS web site that you use. In the output
XML configuration element look for the <varname>userName</varname> attribute.
<example>
<title>Determining the account used as IIS anonymous identity</title>
<programlisting>
<![CDATA[
%windir%\system32\inetsrv\appcmd.exe list config "Default Web Site" ^

<authentication>
<anonymousAuthentication enabled="true" userName="IUSR" />
</authentication>
</security>
</system.webServer>

</programlisting>
</example>
<note>
<para>
If <varname>userName</varname> attribute is not present in the <varname>anonymousAuthentication</varname> element,
or is set to an empty string, then it means that the application pool identity is used as an
anonymous identity for that web site.

</para>
</listitem>
<listitem>
<para>
<varname>log_errors</varname> = <literal>On</literal> - PHP has an error logging facility that can be used to send errors to a file,
or to a service (i.e. syslog) and works in conjunction with the <varname>error_log</varname> directive below. When running under IIS,
the <varname>log_errors</varname> should be enabled, with a valid <varname>error_log</varname>.
</para>
</listitem>
<listitem>
<para>
<varname>error_log</varname> = <literal>&lt;path to the error log file&gt;</literal> - The error_log needs to specify the absolute,

</listitem>
<listitem>
<para>
<varname>cgi.force_redirect</varname> = <literal>0</literal> - This directive is required for running under IIS.
It is a directory security facility required by many other web servers. However, enabling it under IIS will
cause the PHP engine to fail on Windows.

The IIS FastCGI implementation needs this set.
</para>
</listitem>
<listitem>
<para>
<varname>fastcgi.impersonate</varname> = <literal>1</literal> - FastCGI under IIS supports the ability to impersonate
security tokens of the calling client. This allows IIS to define the security context that the request runs under.
</para>
</listitem>
<listitem>
<para>
<varname>fastcgi.logging</varname> = <literal>0</literal> - FastCGI logging should be disabled on IIS. If it is left enabled,

Optional directives
<itemizedlist spacing="compact">
<listitem>
<para>
<varname>max_execution_time</varname> = <literal>##</literal> - This directive tells PHP the maximum amount of time that it can spend
executing any given script. The default for this is 30 seconds. Increase the value of this directive if PHP application take long time to execute.
</para>
</listitem>
<listitem>
<para>
<varname>memory_limit</varname> = <literal>###M</literal> - The amount of memory available for the PHP process, in Megabytes.
The default is 128, which is fine for most PHP applications. Some of the more complex ones might need more.
</para>
</listitem>
<listitem>
<para>
<varname>display_errors</varname> = <literal>Off</literal> - This directive tells PHP whether to include any error messages in the
stream that it returns to the Web server. If this is set to &quot;On&quot;, then PHP will send whichever classes of errors
that you define with the <varname>error_reporting</varname> directive back to web server as part of the error stream.
For security reasons it is recommended to set it to &quot;Off&quot; on production servers in order not to reveal any
security sensitive information that is often included in the error messages.
</para>
</listitem>
<listitem>
<para>
<varname>open_basedir</varname> = <literal>&lt;paths to directories, separated by semicolon&gt;</literal>, e.g.
openbasedir=&quot;C:\inetpub\wwwroot;C:\inetpub\temp&quot;. This directive specified the directory paths where PHP
is allowed to perform file system operations. Any file operation outside of the specified paths will result in an error.
This directive is especially useful for locking down the PHP installation in shared hosting environments to prevent
PHP scripts from accessing any files outside of the web site's root directory.

<listitem>
<para>
<varname>upload_max_filesize</varname> = <literal>###M</literal> and <varname>post_max_size</varname> = <literal>###M</literal> -
The maximum allowed size of an uploaded file and post data respectively. The values of these directives should be

<para>
The <interfacename>Stringable</interfacename> interface denotes a class as
having a <function>__toString</function> method. Unlike most interfaces,
<interfacename>Stringable</interfacename> is implicitly present on any class that
has the magic <function>__toString</function> method defined, although it
can and should be declared explicitly.

Its primary value is to allow functions to type check against the union
type <literal>string|Stringable</literal> to accept either a string primitive
or an object that can be cast to a string.
