configuration - codeigniter correct way to check if libraries/helper/core files is loaded -


i'm using codeigniter 2.

appreciate if show correct way check if following files :
- library file loaded?
- helper file loaded?
- config file loaded?
- model file loaded?
- third_party file loaded?

regards

you can use native php function class_exists() determine if class has been defined, before calling it. in same regard, using method_exists() check if class method exists.

since helpers collection of function, not methods, checking can done using function_exists().

if (class_exists('library'))  {     $this->library->mymethod(); }

for further info please refer
