Sometimes when developing a project, we have some requirements that we need to SESSION is saved to the specified directory, and we can directly use PHP to implement it.

Method/Step

The PHP code is as follows:

<?php
// php自定义session保存目录
//判断CM_cession文件夹是否存在，不存在则创建CM_session文件夹
if(is_dir("CM_session")) {
session_save_path(dirname(__FILE__).&#39;/CM_session/&#39;);
}else {
mkdir("CM_session");
}
// 在php代码中加入如下代码，要加在 session_start() 的前面，并且你的目录下要有CM_session这个文件目录。
// ini_set(&#39;session.save_path&#39;, dirname(__FILE__).&#39;/CM_session/&#39;);
// 或者：session_save_path(dirname(__FILE__).&#39;/CM_session/&#39;);
session_save_path(dirname(__FILE__).&#39;/CM_session/&#39;);
// 以上即将网站生成的session文件保存到了网站当前根目录的CM_session目录下面。
session_start();
?>
