Hide email

In an attempt to automatically hide my email from spam bots, I have been working on a script that turns all email on a page into ASCII, however I am having trouble with one little bit of code.

Douse anyone have a script that can return all emails within a string as an array?

Cheers.

If they are separated by an item explode would split them into an array.

EDIT:

Not sure if you wanted the "email" to be returned as an array (like a single email) if so I believe str_split is what you would be after.

I like to give each user that can receive e-mail a unique id that pertains to the user e-mail address, then on the back end I run the mail algorythim.

The problem is that the code is coming out of the CMS as plain text with the emails within the text

Example:

$content = " Some test text with email1@domain.com two email address email2@domain2.com, there could be many many email addresses. ";

$content = new SpiderTrap($content);

class SpiderTrap{

public function __construct($content){
	return $this->emailFilter($content);
}

public function emailFilter($content){

	$search = "~[\s]+([^\s]+@[^\s]+)[\s]+~iUs";
		// Find the tags
		preg_match_all($search, $content, $matches);

		// Loop through each tag
		for ($i=0; $i < count($matches['0']); $i++) {
			$value =  $matches['1'][$i];
			$email = $this->email2ascii($value);
			$content = str_replace($value, $email, $content);
		}

	return $content;

}

function email2ascii($email){
	$asciiEmail = '';

	$lenght = strlen($email);

	for($i = 0; $i < $lenght; $i++){
		$asciiEmail .= '&#' . ord($email[$i]) . ';';
	}

	return $asciiEmail;
}

}

The problem is with the regular expression, it only ever finds the first email. Is there anyone who has some skill with regular expression who can help me out?

There is a built in option for mail to be sent as html, not other things.

You could load the users email into flash, I don't know of any bots that can read flash.

Are you talking about having a captcha that is required before sending the e-mail to someone, otherwise it runs a loop?
