PHP - How can I determine the numeric sequential value of a character in the english alphabet?

Question

Without using a loop, is there a way (function) to convert, for example, the letter "c" to its numeric sequence in the alphabet (3)?

I'm trying to take a literal string - $var = "c" and apply a function to it that returns 3.

Are there any built-in PHP functions that do this? I can't find any online and would rather avoid writing the function if necessary.

Anyone know of such a conversion function?

Pretty much common to all programming languages - `$var = ord(strtoupper('C')) - 64;` — Mark Baker, Mar 08 '13 at 14:55

$alphabet_position = ord(strtoupper($character)) - ord('A');

Note that this offsets from 0 (ie A = 0); so C = 2 – Mark Baker Mar 08 '13 at 15:09
