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

\] is correct, but note that PHP itself ALSO has \ as an escape character, so you might have to use \\[ (or a different kind of string literal).
