The process of installing OPcache varies depending on which version of PHP
|
|
you're running. Please refer to the appropriate section below.

If you want to use OPcache with
|
|
<link xlink:href="&url.xdebug;">Xdebug</link>, you must load OPcache before
|
|
Xdebug.

OPcache can only be compiled as a shared extension. If you have
|
|
disabled the building of default extensions with
|
|
<option role="configure">--disable-all</option>, you must compile PHP with
|
|
the <option role="configure">--enable-opcache</option> option for OPcache
|
|
to be available.
|
|
</para>
|
|
|
|
<para>
|
|
Once compiled, you can use the
|
|
<link linkend="ini.zend-extension">zend_extension</link> configuration
|
|
directive to load the OPcache extension into PHP. This can be done with
|
|
<literal>zend_extension=/full/path/to/opcache.so</literal> on non-Windows
|
|
platforms, and <literal>zend_extension=C:\path\to\php_opcache.dll</literal>
|
|
on Windows.

You may also want to consider disabling

<link linkend="ini.opcache.save-comments">opcache.save_comments</link>
|
|
and enabling
|
|
<link linkend="ini.opcache.enable-file-override">opcache.enable_file_override</link>,
|
|
however note that you will have to test your code before using these in
|
|
production as they are known to break some frameworks and applications,
|
|
particularly in cases where documentation comment annotations are used.
