In simple way you can go with explode($delimiter, $string);

But in a broad way, with Manual Programming :

        $string = "ab,cdefg,xyx,ht623";
        $resultArr = [];
        $strLength = strlen($string);
        $delimiter = ',';
        $j = 0;
        $tmp = '';
        for ($i = 0; $i < $strLength; $i++) {
            if($delimiter === $string[$i]) {
                $j++;
                $tmp = '';
                continue;
            }
            $tmp .= $string[$i];
            $resultArr[$j] = $tmp;
        }

Outpou : print_r($resultArr);

Array
(
    [0] => ab
    [1] => cdefg
    [2] => xyx
    [3] => ht623
)
