PHP: Split a string in to an array foreach char.

Question

Hi

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

Answer 1

You can access a string using [], as you do for arrays:

for ($i = 0; $i < strlen($str); $i))
    $char = $str[$i];

Answer 2

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.
