Class instantiation in codeigniter - Santi - 03-13-2018 How inbuilt classes like libraries,views are instantiated in codeigniter ? eg:using new operator RE: Class instantiation in codeigniter - dave friend - 03-13-2018 With $this->load->library('lib_name'); RE: Class instantiation in codeigniter - ciadmin - 03-13-2018 ... and then, once you have loaded the class, you can Code: $x = new Lib_name(); Works for models too, but not for views, since they are parsed by the Output or Parser classes. RE: Class instantiation in codeigniter - dave friend - 03-16-2018 And also understand that a call to PHP Code: $this->load->library('lib_name'); // or load->model('lib_name'); The instance created is added to the controller and is accessed using PHP Code: $this->lib_name->some_method(); In a case where the controller is not in scope a reference to can be obtained using get_instance() eg. PHP Code: $CI =& get_instance(); The Utilizing CodeIgniter Resources within Your Library section of the documentation explains this very well. It may be useful to know that classes instantiated using the loader ($this->load->...) are singletons. |
