sorry
maybe you should try this out
checkout the link below
http://php.bieffe.org/manu
$str = '01010101';
$str{0} .. $str{1} .. and so on to get each character
hope this really help
cheers
This little function will convert any string into an array of characters:
function stringtochars($string) {
$chars = array();
for ($i = $j = strlen($string); $i-->0;) $chars[--$j] = $string[$i];
return $chars;
}
It looks a little weird, but it is probably one of the fastest non-native method ways of achieving a string split. Regular expressions work fine, but can be slow if they are called a lot.

...you can, of course, just access the string directly using brackets or braces. Strings behave rather like arrays of characters under PHP.
If you want to create completely separate variables (rather than an array) from the original string, then just use the function like this...
list($bit1, $bit2, $bit3, $bit4, $bit5, $bit6, $bit7, $bit8) = stringtochars($binary);
