<para>
|
|
Performs a syntax (lint) check on the specified
|
|
<parameter>filename</parameter> testing for scripting errors.
|
|
</para>
|
|
<para>
|
|
This is similar to using <command>php -l</command> from the <link
|
|
linkend="features.commandline">commandline</link> except that this
|
|
function will execute (but not output) the checked
|
|
<parameter>filename</parameter>.
|
|
</para>
|
|
<para>
|
|
For example, if a function is defined in <parameter>filename</parameter>,
|
|
this defined function will be available to the file that executed
|
|
<function>php_check_syntax</function>, but output from
|
|
<parameter>filename</parameter> will be suppressed.
|
|
</para>
|
|
<note>
|
|
<!-- See PHP bug #27406 for details on this suppression -->
|
|
<para>
|
|
For technical reasons, this function is deprecated and removed from PHP.
|
|
Instead, use <literal>php -l somefile.php</literal> from the
|
|
<link linkend="features.commandline">commandline</link>.
