Checking for all capitals

[emrys404]

Okay i have tried using ctype_upper() and regex expression preg_match('/^[A-Z]+$/', $text)) to check and see if a string is in all caps. These two work great if there is no spaces but not so great with spaces. Are there any solutions to this world stopping dilemma?

Thanks in advance

Humm...two options I can think of at the moment. First, make the string all upper case if that's the way you need it, strtoupper(). Or, take out the spaces before checking the string. Ex:

$string_no_spaces = str_replace(' ', '', $string);
if (ctype_upper($string_no_spaces)) {
    // Is all upper case.
} else {
    // NOT all upper case.
}

The goal is to not allow them to type in all caps.
One thing i was thinking of was making a copy of the string and converting it all to upper case then using strcasecomp() to compare (ie if they match then the string was in call caps). then i would convert the whole string to lowercase and then use ucwords() . However that seems kinda clunky to me. I cant necessarily just convert each string to lower then ucword() it because that messes up things like B/O Organization (ie. that would make B/o Organization). What do you think?

Thanks in advance,
