I'm using the following regex to match some text..
/<td class="a">(.*?)<br/'
In some instances, I need to match <td class="a bc"
So is there a way to have an optional match for the (space)bc ?
Thanks!

Thank you

What you tried should work...
Code: Select all
[feyd@home]>php -r "echo preg_match('#<td class=\"a( bc)?\">(.*?)<br#is','<td class=\"a bc\">blahblah<br/>');"

Your right it worked! It was a different array key when it gets the optional.. didnt see that. Thanks!
