Returns the PHP source code in <parameter>filename</parameter> with
|
|
PHP comments and whitespace removed. This may be useful for determining the
|
|
amount of actual code in your scripts compared with the amount of comments.
|
|
This is similar to using <command>php -w</command> from the

|
<link linkend="features.commandline">commandline</link>.

This function works as described as of PHP 5.0.1. Before this it would
|
|
