* This helper contains some functions based on the PEAR PHP_Compat library
* http://pear.php.net/package/PHP_Compat
- *
+ *
* The PEAR compat library is a little bloated and the code doesn't harmonize
* well with CodeIgniter, so those functions have been refactored.
* We cheat a little and use CI's _exception_handler() to output our own PHP errors
* so that the behavior fully mimicks the PHP 5 counterparts. -- Derek Jones
