RE: retrieving and showing data - InsiteFX - 07-14-2016

You place the functions in a CI helper say utility_helper

Then load the helper

RE: retrieving and showing data - arma7x - 07-14-2016

OP please learn how to code and debugging properly, it's basic thing. You only post same errors in diferrent scenarios. Have a nice day buddy.

You guys are really patient... I would say that davy_yg is some sort of troll or something spamming all the forum but whatever...

Because an if statement is not valid in the body of a class. You can only define methods, properties, and constants in a class. An if statement would have to be either inside a method or outside of the class. One option would be to do something like this:

PHP Code:
protected function array_to_object($data)
{
    if (function_exists('array_to_object')) {
         return array_to_object($data);
    }
    // ... your existing array_to_object method here
} 

Note that I've declared the method as protected, because leaving the visibility off of the method declaration is the same as declaring a public method, and public methods in controllers can be routed or accessed via the URL.
