Runs PHP interactively. If you compile PHP with the <link
|
||||
linkend="ref.readline">Readline</link> extension (which is not
|
||||
available on Windows), you'll have a nice shell, including a
|
||||
completion feature (e.g. you can start typing a variable name, hit the
|
||||
TAB key and PHP completes its name) and a typing history that can be
|
||||
accessed using the arrow keys. The history is saved in the
|
||||
<filename>~/.php_history</filename> file.

As of PHP 5.1.0, the &cli.sapi; provides an interactive shell using the
|
||||
<option>-a</option> option if PHP is compiled with the <option
|
||||
role="configure">--with-readline</option> option.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
Using the interactive shell you are able to type PHP code and have it
|
||||
executed directly.

||||
</para>
|
||||
|
||||
<example>
|
||||
<title>Executing code using the interactive shell</title>

|

]]>
|
||||
</programlisting>
|
||||
</example>
|
||||
|
||||
<para>
|
||||
The interactive shell also features tab completion for functions,
|
||||
constants, class names, variables, static method calls and class
|
||||
constants.
|
||||
</para>
|
||||
|
||||
<example>
|
||||
<title>Tab completion</title>
|
||||
<simpara>
|
||||
Pressing the tab key twice when there are multiple possible completions
|
||||
will result in a list of these completions:
|
||||
</simpara>
|
||||
<programlisting role="shell">
|
||||
<![CDATA[
|
||||
php > strp[TAB][TAB]
|
||||
strpbrk strpos strptime
|
||||
php > strp
|
||||
]]>
|
||||
</programlisting>
|
||||
<simpara>
|
||||
When there is only one possible completion, pressing tab once will
|
||||
complete the rest on the same line:
|
||||
</simpara>
|
||||
<programlisting role="shell">
|
||||
<![CDATA[
|
||||
php > strpt[TAB]ime(
|
||||
]]>
|
||||
</programlisting>
|
||||
<simpara>
|
||||
It is also possible doing completion on things that have been defined
|
||||
during the interactive shell session:
|
||||
</simpara>
|
||||
<programlisting role="shell">
|
||||
<![CDATA[
|
||||
php > $fooThisIsAReallyLongVariableName = 42;
|
||||
php > $foo[TAB]ThisIsAReallyLongVariableName
|
||||
]]>
|
||||
</programlisting>
|
||||
</example>
|
||||
|
||||
<para>
|
||||
The interactive shell stores your history and can be accessed using the up
|
||||
and down keys. The history is saved in the
|
||||
<filename>~/.php_history</filename> file.

||||

As of [whatever becomes the next version], the &cli.sapi; provides
|
||||
two new &php.ini; settings: <parameter>cli.pager</parameter> and
|
||||
<parameter>cli.prompt</parameter>. The <parameter>cli.pager</parameter>
|
||||
setting allows an external program (such as <filename>less</filename>) to
|
||||
act as a pager for the output instead of being displayed directly on the
|
||||
screen. The <parameter>cli.prompt</parameter> setting makes it possible to
|
||||
change the <literal>php ></literal> prompt.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
In [whatever becoems the next version] it was also made possible setting
|
||||
&php.ini; settings in the interactive shell using a shorthand notation.
|
||||
</para>

||||
|
||||
<example>
|
||||
<title>Setting &php.ini; settings in the interactive shell</title>

<programlisting role="shell">

</programlisting>
|

<simpara>
|

Using backticks it is possible to have PHP code executed in the prompt:
|
||||
</simpara>
|

<programlisting role="shell">

<![CDATA[

<programlisting role="shell">
