How do I match a square bracket literal using RegEx?

Question

What\'s the regex to match a square bracket? I\'m using \\\\] in a pattern in eregi_replace, but it doesn\'t seem to be able to find a ]..

Answer 1

You don't need to escape it: if isolated, a ] is treated as a regular character.
Tested with eregi_replace and preg_replace.

[ is another beast, you have to escape it. Looks like single and double quotes, single or double escape are all treated the same by PHP, for both regex families.

Perhaps your problem is elsewhere in your expression, you should give it in full.
