encrypt $_GET

[dreamwest]

I want to pass a title through $_GET, but i need to encrypt it so no one can alter the title as they are stored in a database

 

Encrypt the link:

$encrypt = "mary had a little lamb"; //encrypt this
$link = "http://site.com/index.php?title={$encrypt}";

 

Link (what the viewer sees) : 

http://site.com/index.php?title=656gyifhkbu+_tr6$fhjgfjhgjkg

 

play.php:

$title = $_GET['title']; //decrypt this so it is the original string "mary had a little lamb"

I don't see how it will have affect encrypting it as the user can still modify the get value, what is your requirement as to why are you passing the value through get ?

[dreamwest]

Already thought of that - ill just amend a secret code to it

 

eg:

 

$encrypt = "mary had a little lamb *check valid*";

 

Then str_replace the *check valid* on the decrypted side

you can check the following, never tried it out but it seems to fit your need
