php_strip_whitespace
(PHP 5, PHP 7)
php_strip_whitespace — Return source with stripped comments and whitespace
Description
$filename
) : string
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.
Return Values
The stripped source code will be returned on success, or an empty string on failure.
Note:
This function respects the value of the short_open_tag ini directive.
Note:
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.
Examples
Example #1 php_strip_whitespace() example
<?php
// PHP comment here
/*
* Another PHP comment
*/
echo php_strip_whitespace(__FILE__);
// Newlines are considered whitespace, and are removed too:
do_nothing();
?>
The above example will output:
<?php echo php_strip_whitespace(__FILE__); do_nothing(); ?>
Notice the PHP comments are gone, as are the whitespace and newline after the first echo statement.
