php_strip_whitespace --
Return source with stripped comments and whitespace
Описание
string php_strip_whitespace ( string filename )
Returns the PHP source code in filename 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 php -w from the
commandline.
Замечание:
This function works as described as of PHP 5.0.1. Before this it would
only return an empty string. For more information on this bug and its
prior behavior, see bug report
#29606.
Возвращаемые значения

on failure.
