在CodeIgniter的模型文件中加载库文件

Question

I want to load library file from model in codeigniter. Can anyone please help me.

Answer 1

You should always load the libraries in controller,as models are always called from controllers.

Anyways you can try like this:

$this->load->library('library_name');
$lib= new library_name();
$lib->somemethod();

Answer 2

Put your file in the library folder and use the following code to load it in the controller:

$this->load->library('your_library');

Remember, do NOT put your code in the system folder's library folder. Put it in the appilcation's library folder.

Once loaded, you can use the classes defined in your library. Remember, libraries work different than models. For Example:

Your library: <? class Foo{ Foo() {} function Bar() {} } ?> <? class Foo{ Foo() {} function Bar() {} } ?> saved as myFoo.php in application/library/

Load it like $this->load->library('myFoo'); then use it like $foo = new Foo(); $bar = $foo->Bar(); $foo = new Foo(); $bar = $foo->Bar();
