I'm pretty new to PHP, and I noticed there are many different ways of handling regular expressions.
This is what I'm currently using:
$replace = array(" ",".",",","'","@"); $newString = str_replace($replace,"_",$join); $join = "the original string i'm parsing through";
I want to remove everything which isn't a-z, A-Z, or 0-9. I'm looking for a reverse function of the above. A pseudocode way to write it would be
If characters in $join are not equal to a-z,A-Z,0-9 then change characters in
$newString = preg_replace('/[^a-z0-9]/i', '_', $join);
This should do the trick.
