You need to cast your string as an array..

<?php

$b = "abcdefgh" ;
$b = (array)$b;

foreach( $b as $y ) {
	echo $y ;
};

?>

Works.

This is a thing to think about:
Since strings are NOT accepted as foreach input we could
add that by delivering eash single character.

>php -r '$a="abc";foreach($a as $i => $c) echo "$i:$c\n";'
0:a
1:b
2:c
