Splitting a string

[ForgotMyPass]

How can I split a string int an array for letters? For example:

$cat = "food";

and make $catarray = array("f","o","o","d")

Anything for php 4?

Same page. User comments.

function str_split($str,$num = '1') {
    if($num < 1) return FALSE;
    $arr = array();
    for ($j = 0; $j < strlen($str); $j= $j+$num) {
        $arr[] = substr($str,$j,$num);
    }
    return $arr;
}

In your case, you dont need the split_length functionality, so you can use:

function strSplit($str) {
	$ret = array();
	$len = strlen($str);
	for ($i = 0; $i < $len; $i++) {
		$ret[$i] = $str{$i};
	}
	return $ret;
}
