Note that if string is empty, the function will return TRUE
$some_string = "12345";
//This will output 1 (TRUE)
echo(ctype_digit($some_string));
$some_string = "ab12";
//This will output 0 (FALSE)
echo(ctype_digit($some_string));
$some_string = "";
//This will output 1 (TRUE)
echo(ctype_digit($some_string));
