在PHP / HTML文本输入中，如何删除我不想提交到数据库的某些部分？

Question

When people edit their account on my site, they get confused and think they have to type out all of their steam profile link, e.g. http://steamcommunity.com/id/###### When all they have to type in the text field is, #######, so if they mess up, how do I remove everything from their input, except the ##### part?

Answer 1

How about:

$lastPart = array_pop(explode('/', $_SERVER['REQUEST_URI']));

This will retrieve the last element of the REQUEST_URI.
