What's needed for PHP's mcrypt_decrypt()?

Question

I have a script that uses mcrypt_decrypt() function, but I get the following error

Fatal error: Call to undefined function mcrypt_decrypt()

What modules/libraries do I need to include to use this function? Or is there another reason I'm getting the error?

Thanks

Answer 1

And be carefull about the folder in the phpinfo page : "Scan this dir for additional .ini files" and the next : "Additional .ini files parsed ".

Please see:

• Mcrypt Requirements

You need to compile your PHP with --with-mcrypt[=DIR] and have libmcrypt Version 2.5.6 or greater on your machine.
