There's no is_char function

[chuck]

I'm scanning email files and I've got a script that checks
to see if column 1 is a char (a-z) and the word ends with
a ":" - UgggggggggggggL E. Sure would be nice if I could
$x = explode (" ", $line)
if (is_chr($x[0])
if (strstr($x, ":")
--still in header--


anyone have a better way?

Try Regular Expressions

Happy Coding :)

The function you're looking for is ctype_alpha(). Naturally, regular
Expression is a better solution.

Not sure what "the word ends with a ':'" means.

To see if a string ($str) starts with a-z, you can do:

if (preg_match("/^[a-z]/", $str)) {
// column 1 is a character
}

To see if a string ends with a ":" you can do:

if (substr($str, -1) == ':') {
// ends with a ":"
}

For the char thing, you could, in general, use this:

function is_char($c) {
if (strlen($c) == 1 && preg_match("/[a-z]/", $c)) {
// to allow capitals, use "/[a-zA-Z]/"
return TRUE;
}
return FALSE;
}
