Re: [PHP] echo text - anti-spam-spider measure

You could also use %XX in HEX on the mailto:

I'm not sure with both of your questions. I'm too lazy to try.

Untested: But to encode it, you would use

preg_replace_callback('~([\d\w])~', create_function('$a', 'return
"&#".ord($a[0]).";";'), $theEmail);

Hopefully that works?

Try using Javascript? Or use all entities? For example:
mailto:php-general@xxxxxxxxxxxxx would turn into

I need an anti-spam-spider measure for my site. Too many
addresses are
getting raked. In once instance, I created a flash page:
http://erasethis.glquebec.org/English/contact.htm
But I just don't have the time to create a flash image for
every
single
instance, most of which come from dynamically printed PHP
pages from a
MySQL database.

Could I dynamically create a flash image, input the email and
tell the
flash image to mailto:the@xxxxxxxxxxx?

Do anyone have a solution? Does one already exist?

My idea was to create a PHP script and output to a png. But I
see many
problems, including:

1) How do I avoid echoing the email address in the <a
href=""> tag?
2) How would I write a png that would be long and high
enough?
3) How would the same script display the png?

In short, I can't see far enough how to do this and avoid
spider-raking
in the HTML or header the content of the image.

Any advice, code or input would be appreciated,
John

<a href="<?php

#what do I put here?
$mydata->email = "me@xxxxxxxxxxxxx";
echo $??????????;

?>"><img src="<?php
|header('Content-type: image/png');|
#How do I display the image?

$mydata->email = "me@xxxxxxxxxxxxx";
echo $??????????;

?>" width="???" height="???">
