Usually PHP makes HTTP requests, and you can use GET or POST to receive parameters. Sometimes you need to execute PHP as a script under a shell command, such as a scheduled task. This involves the issue of how to pass parameters to php under the shell command. There are usually three ways to pass parameters.

1. Use $argv or $argc parameter to receive

<?php
/**
 * 使用 $argc $argv 接受参数
 */
 echo "接收到{$argc}个参数";
print_r($argv);

Copy after login

Execute

[root@DELL113 lee]# /usr/local/php/bin/php test.php
接收到1个参数
Array
(
    [0] => test.php
)
[root@DELL113 lee]# /usr/local/php/bin/php test.php a b c d
接收到5个参数Array
(
    [0] => test.php
    [1] => a
    [2] => b
    [3] => c
