_php Example of $this->load->library () usage analysis in CI framework

This paper analyzes the usage of $this->load->library () in CI framework. Share to everyone for your reference, specific as follows:

The first time I failed to load, originally is the file name and class name for different reasons, first summed up about CI loading your own class file considerations:

1. Third party loaded items should be placed under Application/libraries documents

2. FileName and class name should be the same, and the first letter uppercase, such as FileName excel.php class name should be Excel

3. Adoption:$this->load->library (' class '); The way to load where you need it

4. Can also be loaded in the application/config/autoload.php, add in the file

$autoload [' libraries '] = Array (' Excel ');

5. When loading, if libraries has more than one folder, such as myfile can be loaded in the following way:

$this->load->library (' myfile/class ');

6. The second parameter can be placed in the following way:

$config = Array (
 ' mailtype ' => ' html ', '
 charset ' => ' utf-8,
 ' priority ' => ' 1 '
);

$this->load->library (' email ', $config);

7. The third parameter can use your custom name in the following way:

$this->load->library (' Session ', ', ' my_session ');
The session class can now be accessed in the following way:
$this->my_session->set_userdata ("Session name", "Session value");
