PHP Split a string in to an array foreach char

Question

I am making a method so your password needs at least one captial and one symbol or number  I was thinking of splitting the string in to lose chars and then use preggmatch to count if it contains one capital and symbol number   however i did something like this in action script but can t figure out how this is called in php  i cant find a way to put every char of a word in a array   AS3 example      for var i uint   0  i  lt  thisWordCode length -1   i          thisWordCodeVerdeeld i    thisWordCode charAt i         trace  thisWordCodeVerdeeld i        Thanks  Matthy

You can access characters in strings in the same way as you would access an array index, e.g.

$length = strlen($string);
$thisWordCodeVerdeeld = array();
for ($i=0; $i<$length; $i++) {
    $thisWordCodeVerdeeld[$i] = $string[$i];
}

You could also do:

$thisWordCodeVerdeeld = str_split($string);

However you might find it is easier to validate the string as a whole string, e.g. using regular expressions.
