IF statement help

[mufka]

I need to create an if statement that checks to see if a variable is a letter from a-z. If the variable is a-z it exits. If the variable is anything else it will do something else. I can't seem to find the correct comparison operator.

Thanks

Something like this should work:

$haystack="abcdefghijklmnopqrstuvwxyz";
if(strpos($haystack,$myvar)){
[green]//do something[/green]
}

It checks wether the contents of $myvar exists in the given string.
