A deque<char> or a char* ? Pass -- this looks like a question for PHP's developers, not the denizens of php-general who are mostly just humble users.

Or does it jump to the n-th char directly? Given the nature of PHP, I'd be astonished if it did 1. But again, this looks more like a question for the PHP developers, not php-general. Cheers!
