You did the VERY hard way ... here is a MUCH easier and less code way:
$string = 'Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been around five centuries. It has survived not only five centuries, remaining essentially unchanged.';
$output = ['a'=>0, 'e'=>0, 'i'=>0, 'o'=>0, 'u'=>0];
$string_split = str_split($string);
$values =
foreach($output as $key=>$val) {
if(array_key_exists($key, $values)) {
$output[$key] = $values[$key];
}
}
echo'<pre>';
print_r($output);
echo'</pre>';
-- Result:
Array
(
[a] => 7
[e] => 19
[i] => 14
[o] => 6
[u] => 9
)

Maybe you can solve it easier in 5 lines of code:

$loremIpsum = "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged";
$vowelArray = ["a" => 0, "e" => 0, "i" => 0, "o" => 0, "u" => 0];
foreach ($vowelArray as $key => &$value) {
$value = substr_count($loremIpsum, $key);
}
print_r($vowelArray);die();
