'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



Solution 1:[1]

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

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

Solution 2:[2]

Since str_split() function is not multibyte safe, an easy solution to split UTF-8 encoded string is to use preg_split() with u (PCRE_UTF8) modifier.

preg_split( '//u', $str, null, PREG_SPLIT_NO_EMPTY )

Solution 3:[3]

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

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

Solution 4:[4]

Try this, It works beter for UTF8 characters (Kurdish, Persian and Arabic):

<?php
$searchTerm = "?????";
$chars = preg_split("//u", $searchTerm, -1, PREG_SPLIT_DELIM_CAPTURE);
foreach($chars as $char){echo $char."<br>";}
?>
