PHP: Split a string in to an array foreach char


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 < 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.

you can convert a string to array with str_split and use foreach

$chars = str_split($str);
foreach($chars as $char){
    // your code
