php在CLI模式下传入值的几种方法小结
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

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
