Php 5.3 mcrypt not working on CentOS 6.3 32-bit

Question

My CodeIgniter application works fine on Amazon EC2 64-bit AMI micro instance thanks to @stormdrain who recommended I install mcrypt to resolve a non-functioning $this->encrypt->decode(...); which was not decrypting my key. Its working now. However, when I copied the same application (using scp) to my local 32-bit machine running CentOS 6.3, I'm getting the same problem ($this->encrypt->decode(...); is not decrypting my key).

So I installed mcrypt sudo yum install php-mcrypt. However, which php-mcrypt and which mcrypt was not found. whereis php-mcrypt and whereis mcrypt turned up nothing. sudo yum php-mcrypt resulted in Package php-mcrypt-5.3.3-1.el6.rf.i686 already installed and latest version. Nothing to do. sudo yum libmcrypt revealed Package libmcrypt-2.5.7-1.2.el6.rf.i686 already installed and latest version. Nothing to do. php --version showed PHP 5.3.3. I searched for mcrypt in the php.ini file but found nothing. echo phpinfo only found one entry besides Additional .ini files parsed: /mcrypt.ini. However, I can't locate this file. The same Encryption Key is already set in CodeIgniter's config.php.

I'm not sure what I'm doing wrong here. Any assistance will be appreciated. Thanks in advance.

This seem to be a issue in the 32bit version of mcrypt when using yum install php-mcrypt to install. Take a look @ Installing php-mcrypt on centos 6.4 (32 bytes) causes problem, the mcrypt.ini file has the wrong entry

You need to edit /etc/php.d/mcrypt.ini and change

extension=module.so

To

extension=mcrypt.so

Then save and restart apache.
