- Remove text between two HTML comments.
Well, one way is to make use of assertions. By using look behind and look ahead assertions (they are not included in any matches), you can grab what is not part of them:
$tmp_tpl = preg_replace(‘#(?<=<!–COMMENTBOX–>).+(?=<!–ENDCOMMENTBOX–>)#’, ”, $tmp_tpl);
Of course, to test this out, when you say echo $tmp_tpl, you won’t see anything, as these are comment tags (and thus do not display). So you would have to right-click and view source to see the ‘<!–COMMENTBOX–><!–ENDCOMMENTBOX–>’ effect.
