How can PHP be utilized to convert email addresses into ASCII characters for spam protection?

To convert email addresses into ASCII characters for spam protection, you can use PHP to obfuscate the email address in the HTML source code. This can help prevent email harvesting bots from easily collecting email addresses for spamming purposes. 

<?php
function convertEmailToAscii($email) {
  $asciiEmail = '';
  for ($i = 0; $i < strlen($email); $i++) {
    $asciiEmail .= "&#" . ord($email[$i]) . ";";
  }
  return $asciiEmail;
}

$email = "example@example.com";
$obfuscatedEmail = convertEmailToAscii($email);

echo $obfuscatedEmail;
?>
