LEARN ABOUT PHP
php_strip_whitespace
PHP_STRIP_WHITESPACE(3) 1 PHP_STRIP_WHITESPACE(3)php_strip_whitespace - Return source with stripped comments and whitespaceSYNOPSIS
string php_strip_whitespace (string $filename)
DESCRIPTION
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.
PARAMETERS
o $filename
- Path to the PHP file.
RETURN VALUES
The stripped source code will be returned on success, or an empty string on failure.
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(3) 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.
