json_encode Does Not Exist

It’s broken because the JSON module for php isn’t installed and/or loaded! So, install it!

1. Install the PHP Developer Package
   yum install php-devel
2. Compile the JSON PHP Module with PEAR or PECL (PEAR Recommended)
   PEAR » pear install pecl/json
   PECL » pecl install json
3. Configure PHP to Load JSON PHP Module
   Create a file json.ini in the directory /etc/php.d/ with this line:
   extension=json.so

See, that wasn’t that hard, was it?
