Hello,

 Thanks for all help in advance.

I'm coding with PHP and i need to recognize 2 words and one letter in a middle from input. I mean i have a variable with string and i know what that string must be formated like 2 words and one letter in a middle. "hello8 g mike213" this is correct string. no "hello~8 8 asud+2"

can someone give any help on this. thanks.

This matches on:

[one or more alphanumeric characters][one or more whitespace characters][one letter][one or more whitespace characters][one or more alphanumeric characters]
