The PHP equivalent is chop(). Then loop through the string, xoring (presumably that's it - can't find it in VB4 refs) each character with hex FF and appending the result to string var sU You can access each character in a string as an array element; so if the string $s contains hello then: $s[0] = h $s[1] = e and so forth. The PHP xor operator is the caret ^ That should give you enough information to be able to dod what you want.
