Hi Ron,
Also in PHP a string is actually an array of characters. Maybe you can pick
out each character and compared it to the character in the same position of
the known string!
Example:
// Get the first character of a string
$str = 'This is a test.';
$first = $str{0};
// Get the third character of a string
$third = $str{2};
Cheers, RICO
