Ascii to Binary

Hi all,

How can you convert an ascii string (such as "Hello World") to binary 0 and 1s in PHP?

Thanks in advance.

in php you would have to make a function yourself and convert all letters to hex then go to binary. that would be pretty hard to come up with.

This seems to work but I am sure there is an easier method:

PHP Code:

---

<?
$DecString = "Hello World";
for ($i = 0; $i <= strlen($DecString); $i++) {
    $char = substr($DecString,$i,1);
    $dec = ord($char);
    $bin = base_convert($dec, 10, 2);
    $bin = str_pad($bin, 8, "0", STR_PAD_LEFT);
    print $bin;
}
?>

ty!
