    if (
ctype_upper($testcase)) {
        echo 
"The string $testcase consists of all uppercase letters.\n";

Notes

Note:

If an integer between -128 and 255 inclusive is provided, it is interpreted as the ASCII value of a single character (negative values have 256 added in order to allow characters in the Extended ASCII range). Any other integer is interpreted as a string containing the decimal digits of the integer.
