Someone posted a str2bin fonction, this is a simpler version, using more PHP internal functions.
<?php
/**
* Returns an ASCII string containing
* the binary representation of the input data .
**/
function str2bin($str, $mode=0) {
$out = false;
for($a=0; $a < strlen($str); $a++) {
$dec = ord(substr($str,$a,1));
$bin = decbin($dec);
$bin = str_pad($bin, 8, "0", STR_PAD_LEFT);
/* Default-mode */
if ( $mode == 0 ) $out .= $bin;
/* Human-mode (easy to read) */
if ( $mode == 1 ) $out .= $bin . " ";
/* Array-mode (easy to use) */
if ( $mode == 2 ) $out[$a] = $bin;
}
return $out;
}
?>
