Check if a String is ALL CAPS in PHP

Question

What\'s the best way to see if a string contains all capital letters? I still want the function to return true if the string also contains symbols or numbers.

Answer 1

I think you are looking for this function

$myString = "ABCDE";
if (ctype_upper($myString)) // returns true if is fully uppercase
{
    echo "the string $myString is fully uppercase";
}

Hope it helps
