php preg_replace remove
with style attr

Question

<br style="clear: both">

The following regex doesn't work for me, what am I doing wrong?

return preg_replace('#<br[^>]+style="clear:both"[^/>]#is', '',  $output);

thank you.

doesn't work because you don't match space between "clear:" and "both" — soju, Feb 25 '11 at 16:55

If your string is always:

<br style="clear: both">

You can use str_replace instead:

return str_replace('<br style="clear: both">', '',  $output);

Use some parser HTML instead.

You may escape chars like =, :, <, >, etc. Something like this:

<?php    
return preg_replace('#\<br[^>]+style\=\"clear\:both\"[^/>]#is', '',  $output);
?>

More better example:

<?php
return preg_replace('#\<br*.?\>#is', '',  $output);
?>

No, those characters have no special meaning, so escaping them is pointless. Also, the `*.?` in your second suggestion should be `.*?`. – Alan Moore Feb 25 '11 at 20:55

Try this :

#<br *style="clear: *both"/?>#is
