PHP_STRIP_WHITESPACE(3) 						 1						   PHP_STRIP_WHITESPACE(3)

php_strip_whitespace - Return source with stripped comments and whitespace

SYNOPSIS

       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.
