[SOLVED] silly hex thingy

[AV1611]

I have been trying to figure out how to do this, but can't seem to get the right functions from the manual:

 

I want to convert the follow string to hex and back

 

$string="mary had a little lamb";

$string2=somefunction($string); //now it's in HEX

$string3=someotherfunction($string2); // now it's back to normal

echo $string3; //produces

mary had a little lamb

 

Thanks...

you should check the ord() function and the dechex()

 

check them in the manual...

What do you want to convert - is it the numbers used to represent the characters? If so try looking at this function

$string="mary had a little lamb";
$string2= bin2hex($string); //now it's in HEX
$string3= pack('H*', $string2); // now it's back to normal
echo $string3; //produces

 

Result"

mary had a little lamb

Thank you all for the help.  I haven't figure out what to do with this, but I'm trying to come up with a "email-havester" proof way of using email addresses on a website, etc.  Maybe this is dead end, but I've never seen this approach before.

 

The idea is to do this instead of posting an email addy:

 

<a href="whatever.php?data=6f7370726579407472757468736f6c64696572732e636f6d" target="_blank">[click to see my email addy]</a>

 

You could actually display addy and an <img> as part of the href...

 

you get the idea... Maybe make a function for a CMS? it's still just an idea...

 

At least the actual email addy is nowhere on the website, so can't be havested...

I haven't worked it all out yet and it may just be a silly dead end, but hey, it's the weekend

Use a contact form and php so that the e-mail address is never seen on the page.

That's what I do now, I had posting on a forum / cms/ blog in mind.  The idea *might* be to create a PNG with the posters email addy, and use that in the href somehow.  It's just an idea.  That's all.
