Dividing a string into 2 letter pieces

[Gero_Master]

Hello!

Google was no help when I tried to search for a function that would seperate a html color into 2 letter pieces. My code allready erases the # -sign in front of the color.

like: #a3f4f4
into: a3 f4 f4

which i could then use like
$c['0']
$c['1']
$c['2']

It needs to be divided for GD's color functions.

Thank you

$var = "FFCCDD";
$code1 = substr($var,0,-4); // FF
$code2 = substr($var,2,2); // CC
$code3 = substr($var,4,2); // DD

Another possibility:

$string = 'AABBCC';
preg_match_all('(\w\w)', $string, $matches);

$matches becomes an array with $matches[0] containing "AA", etc.
