Regular Expression to collect everything after the last /

Question

I\'m new at regular expressions and wonder how to phrase one that collects everything after the last /.

I\'m extracting an ID used by Google\'s GData.

Answer 1

Generally:

/([^/]*)$

The data you want would then be the match of the first group.

Edit   Since you’re using PHP, you could also use strrchr that’s returning everything from the last occurence of a character in a string up to the end. Or you could use a combination of strrpos and substr, first find the position of the last occurence and then get the substring from that position up to the end. Or explode and array_pop, split the string at the / and get just the last part.
