<?php

$str = " ";
for ( $pos=0; $pos < strlen($str); $pos ++ ) {
$byte = substr($str, $pos);
echo 'Byte ' . $pos . ' of $str has value ' . ord($byte) . PHP_EOL;
}
?>

<?php
$str = " ";
for ( $pos=0; $pos < strlen($str); $pos ++ ) {
$byte = substr($str, $pos);
echo 'Byte ' . $pos . ' of $str has value ' . ord($byte) . PHP_EOL;
}
?>
