This function returns the string $str in htmlentity hex format (&#xnumber;).
It is useful to prevent spam bots indexing your email adress.
<?php
function hexentities($str) {
$return = '';
for($i = 0; $i < strlen($str); $i++) {
$return .= '&#x'.bin2hex(substr($str, $i, 1)).';';
}
return $return;
}
?>
example:
<?php echo 'email:
<address>'.hexentities('foo@bar').'</address>'; ?>
will return:
email:
<address>foo@bar</address>
the browser will show foo@bar.
