Question

Im try replace

http://site.com/13/new new (2011).html

to

http://site.com/13/new_new_2011.html

Here is my code,

<a href="<?php echo $row->id;?>/<?=preg_replace('#[^\w\-]+#','_', strtolower($row->showTitle()))?>.html">

$row->showTitle() is a title like New New (2011)

but problem is because my links now looks like this

http://site.com/13/new_new_2011_.html

I need to remove last “_” from url _.html

Answer 1

Try this :

 <a href="<?php echo $row->id;?>/
 <?=trim(preg_replace('#[^\w\-]+#','_', strtolower($row->showTitle())), '_')?>.html"> 

It will remove any trailing underscore.
