这篇文章主要为大家详细介绍了CI框架源码阅读,系统常量文件constants.php的配置用法,具有一定的参考价值,可以用来参考一下。
感兴趣的小伙伴,下面一起跟随四海网的小玲来看看吧!
配置系统常量代码如下:
[php]
<?php
/* 四海网 www.q1010.com */
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
/*
|--------------------------------------------------------------------------
| File and Directory Modes
|--------------------------------------------------------------------------
| These prefs 控制台、首选项 are used when checking and setting modes when working
| with the file system. The defaults are fine 罚款 on servers with proper
| security, but you may wish (or even need) to change the values in
| certain environments (Apache running a separate process for each
| user, PHP under CGI with Apache suEXEC, etc.). Octal values should
| always be used to set the mode correctly.
*/
define('FILE_READ_MODE', 0644);
define('FILE_WRITE_MODE', 0666);
define('DIR_READ_MODE', 0755);
define('DIR_WRITE_MODE', 0777);
/*
|--------------------------------------------------------------------------
| File Stream Modes 文件流模式
|--------------------------------------------------------------------------
| These modes are used when working with fopen()/popen()
*/
define('FOPEN_READ', 'rb');
define('FOPEN_READ_WRITE', 'r+b');
define('FOPEN_WRITE_CREATE_DESTRUCTIVE', 'wb'); // truncates existing file data, use with care
define('FOPEN_READ_WRITE_CREATE_DESTRUCTIVE', 'w+b'); // truncates existing file data, use with care
define('FOPEN_WRITE_CREATE', 'ab');
define('FOPEN_READ_WRITE_CREATE', 'a+b');
define('FOPEN_WRITE_CREATE_STRICT', 'xb');
define('FOPEN_READ_WRITE_CREATE_STRICT', 'x+b');
/* End of file constants.php */
