php在CLI模式下传入值的几种方法

php本身是一种脚本语言,在命令行环境中可以高效的进行一些操作,但是在CLI(命令行界面 Command Line Interface)如何传入值呢?

下面介绍本人知道的3种方法。

一 .   getopt (注意:PHP 4 >= 4.3.0, PHP 5)  

我们建立如下文件:test.php

$opt= getopt('m:n:');
// $value_m= $opt['m'];
// $value_n= $opt['n'];
print_r($opt);

然后运行命令

php test.php -mvaluem -n value n

结果如下:

详情请看手册 :http://www.php.net/manual/zh/function.getopt.php

二.  $argv

我们修改一下刚才的test.php文件,内容改成如下:

 

if($argc> 1){
var_dump($argv);
}

运行

php test.php 1 2 c

结果如下:

 

详情参见手册:http://www.php.net/manual/zh/reserved.variables.argv.php

三. linux的STDIN

在linux中

stdout标准输出,默认是终端
stdin 标准输入,默认是键盘
stderr 标准错误输出,默认是终端

所以,我们修改刚才的test.php文件

fwrite(STDOUT, "Enter your name: ");
$name = trim(fgets(STDIN));
fwrite(STDOUT, "Hello, $name!");

我们运行

php test.php

此时屏幕输出:Enter your name:

我们在后面输入:tiyee然后回车

此时屏幕会出现Hhellow,tiyee

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

PHP sessions have a significant impact on application performance. Optimization methods include: 1. Use a database to store session data to improve response speed; 2. Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.
