This article analyzes $this->load- in CI framework >Usage of library(). Share it with everyone for your reference, the details are as follows:

My first loading failed. It turned out to be because the file name and class name were different. Let me first summarize the precautions for loading your own class files in CI:

1. Third-party loading files should be placed under the application/libraries file

2. The file name and class name should be the same, and the first letter should be capitalized. For example, the file name Excel.php and the class name should be Excel

3. Load where you need by: $this->load->library('class');

4. You can also load it in application/config/autoload.php and add

to the file.

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

5. When loading, if libraries have multiple folders, such as myfile, it can be loaded in the following way:

$this->load->library('myfile/类');

6. The second parameter can be placed as follows:

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

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

7. The third parameter can use your customized name as follows:

$this->load->library('session', '', 'my_session');
// Session 类现在可以通过下面的方式访问:
$this->my_session ->set_userdata("session名","session值");
