Replace/remove if starts with

[newbtophp]

Hi,

 

Im trying to modify the following expression:

 

$str = preg_replace('~^\s*\?>~', '', $str);

 

Currently it replaces ?> if its proceeded by whitespace, however I also want it to replace the ?> if its not proceed by <?(php)? before the ?>, I've tried the following:

 

$str = preg_replace( '~^(?<!<\?)\s*\?>~', '', $str);

 

But that did'nt seem to work.

however I also want it to replace the ?> if its not proceed by <?(php)? before the ?>

 

.. on the same line or throughout the string?

Throughout so if theirs no <?php opening tag before it remove it.
