Question

I’m trying to remove currency symbols from a string, but getting an ‘undefined variable’ error. Sorry if this is totally dumb, I’m a newbie!

<? if ($event->ticket_cost) : ?>
   <? $cost = $event->ticket_cost ?>
   <? $cost = preg_replace("€£$","", $cost) ?>
   <?=$cost ?>
   <? else : ?>
   <? echo '' ?>
<? endif ?>

Thanks!

You need to use delimitters:

preg_replace("#€£\$#","", $cost) ?>

Also since $ is special character in regex, you need to escape it with backslash like above.

Also you are using <?, it should be <?= or better <?php unless you are not using any other specialized setting or stuff.
