[RESOLVED] Regex expression for this. Please help.

[The-Master]

I really am rubbish at writing regular expressions, it is the one bit of programming that I don't understand.

How would I go about finding an expression in a string which has 40alphanumeric characters then a dot then another 40alphanumeric characters like the string below. Thanks in advance. 🙂

For preg_* functions:

'/[a-z0-9]{40}\.[a-z0-9]{40}/i'
