Malko za Stringove

imam edin string koito e sas 21 elementa
kak moga da go razdelja na po 7 elementa?

<?
function a_split($str,$chunklen=7)
{
$str = chunk_split($str,$chunklen,"\#");
return explode("\#",$str);
}

$str = "aaaaaaaaaaaaaaaaaaaaa";
var_dump(a_split($str));
?>

има и други начини разбира се.

<?
function a_split($str,$chunklen=7)
{
$i=0;$val=0;$arr[0]='';
while($i<strlen($str)) {
$arr[$val] .= $str[$i++];
$val = ($i%$chunklen)?$val:$val+1;
}
return $arr;
}

$str = "aaaaaaaaaaaaaaaaaaaaa";
var_dump(a_split($str));
?>
