Question

I have a string that has php code in it, I need to remove the php code from the string, for example:

<?php $db1 = new ps_DB() ?><p>Dummy</p>

Should return <p>Dummy</p>

And a string with no php for example <p>Dummy</p> should return the same string.

I know this can be done with a regular expression, but after 4h I haven’t found a solution.

Answer 1

 <?php
 function filter_html_tokens($a){
    return is_array($a) && $a[0] == T_INLINE_HTML ?
      $a[1]:
      '';
 }
 $htmlphpstring = '<a>foo</a> something <?php $db1 = new ps_DB() ?><p>Dummy</p>';
 echo implode('',array_map('filter_html_tokens',token_get_all($htmlphpstring)));
 ?>

As ircmaxell pointed out: this would require valid PHP!

A regex route would be (allowing for no ‘php’ with short tags. no ending ?> in the string / file (for some reason Zend recommends this?) and of course an UNgreedy & DOTALL pattern:

preg_replace('/<\\?.*(\\?>|$)/Us', '',$htmlphpstring);
