Regex with META characters PHP

Question

I have a string: http:\/\/example\.com

I try to regex this to be: http://example.com

I've used preg_replace('//', '', $string) but it is not working.

Could you help me, please?

You need to escape special characters inside regex. It should be `/(\\)/` — vrintle, Oct 16 '18 at 07:43

You should escape a backslash with another backslash to denote one literal backslash, but for the two backslashes to be passed to the regex parser after the interpretation of the compiler, you need to escape each backslash with another backslash:

preg_replace('/\\\\/', '', $string)

Had an extra space due to your pre-edit post. It should work with your edited post now. – blhsing Oct 16 '18 at 07:48
