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.

token_get_all - Split given source into PHP tokens

SYNOPSIS

       array token_get_all (string  $source)

DESCRIPTION

       token_get_all(3) parses the given $source string into PHP language tokens using the Zend engine's lexical scanner.

	For a list of parser tokens, see "List of Parser Tokens", or use token_name(3) to translate a token value into its string representation.

PARAMETERS

	      o $source
		- The PHP source to parse.

RETURN VALUES

	An  array  of token identifiers. Each individual token identifier is either a single character (i.e.: ;, ., >, !, etc...), or a three ele-
       ment array containing the token index in element 0, the string content of the original token in element 1 and the line number in element 2.

EXAMPLES

       Example #1

	      token_get_all(3) examples

	      <?php
	      $tokens = token_get_all('<?php echo; ?>'); /* => array(
								array(T_OPEN_TAG, '<?php'),
								array(T_ECHO, 'echo'),
								';',
								array(T_CLOSE_TAG, '?>') ); */

	      /* Note in the following example that the string is parsed as T_INLINE_HTML
		 rather than the otherwise expected T_COMMENT (T_ML_COMMENT in PHP <5).
		 This is because no open/close tags were used in the "code" provided.
		 This would be equivalent to putting a comment outside of <?php ?> tags in a normal file. */
	      $tokens = token_get_all('/* comment */'); // => array(array(T_INLINE_HTML, '/* comment */'));
	      ?>
