[RESOLVED] Test string for CAPS

[ts10]

I'm amazed that I can't figure this out or find a function...but I need to find out how to test a string for caps letters. I have to display different output based on a character being caps or not.

For instance
$test = cAps
if ($test[0] IS CAPS) { }
if ($test[1] IS CAPS) { }
if ($test[2] IS CAPS) { }

etc.

Any ideas? What am I missing?

Thanks so much!

A couple ways:

if(preg_match('/[A-Z]/', $string))
{
   // caps found
}

if(strtolower($string) != $string)
{
   // caps found
}

Sounds like a job for the ctype functions, e.g. [man]ctype_upper/man (since you appear to want to check each character individually).

Also note that you could use a [man]for/man loop on a string to examine it character-by-character.

ctype_upper worked great. Thanks!
