[SOLVED] Remove text between two HTML comments.

[JasonLewis]

I'm not sure why this isn't working, but it isn't. I just can't seem to get it.

 

This is my expression:

$tmp_tpl = preg_replace("#<!--COMMENTBOX-->(.*?)<!--ENDCOMMENTBOX-->#", "", $tmp_tpl);

 

I just want to replace ANYTHING between the two tags with nothing.

 

Cheers everyone.

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.

 

Cheers,

Use the /s modifier: #<!--COMMENTBOX-->(.*?)<!--ENDCOMMENTBOX-->#s.

Thanks for the replies guys. Adding the modifier worked though, cheers.
