find and remove text from string

[harmor19]

I have a textarea where the admin can enter a string.
If the admin types "[7]" into the text area I'd like to use a code to remove the brackets so the result would be "7".
I could do a simple str_replace if I knew the value was going to be "[7]" but there's no guarantee it will be.

Try preg_replace() instead.

$str = preg_replace('/\[(.*?)\]/', '$1', $str);

I have to leave soon so I'll try it later today.

Thanks, it works.
