$argv

$argv — 传递给脚本的参数数组

说明

包含当运行于命令行下时传递给当前脚本的参数的数组。

注意: 第一个参数总是当前脚本的文件名，因此 $argv[0] 就是脚本文件名。

注意: 这个变量仅在 register_argc_argv 打开时可用。

警告

要测试脚本是否从命令行运行，应使用 php_sapi_name()，而不是检查是否设置了 $argv 或 $_SERVER['argv']。

示例

示例 #1 $argv 示例

<?php
var_dump($argv);
?>

当使用这个命令执行：php script.php arg1 arg2 arg3

以上示例的输出类似于：

array(4) {
  [0]=>
  string(10) "script.php"
  [1]=>
  string(4) "arg1"
  [2]=>
  string(4) "arg2"
  [3]=>
  string(4) "arg3"
}

注释

注意:
也可以在 $_SERVER['argv'] 中获取。

Please note that, $argv and $argc need to be declared global, while trying to access within a class method. 

<?php
class A
{
    public static function b()
    {
var_dump($argv);
var_dump(isset($argv));
    }
}

A::b();
?>

will output NULL bool(false)  with a notice of "Undefined variable ..."

whereas global $argv fixes that.

To use $_GET so you dont need to support both if it could be used from command line and from web browser.

foreach ($argv as $arg) {
    $e=explode("=",$arg);
    if(count($e)==2)
        $_GET[$e[0]]=$e[1];
    else    
        $_GET[$e[0]]=0;
}

You can reinitialize the argument variables for web applications. 
So if you created a command line, with some additional tweaks you can make it work on the web.

If you come from a shell scripting background, you might expect to find this topic under the heading "positional parameters".

Sometimes $argv can be null, such as when "register-argc-argv" is set to false.  In some cases I've found the variable is populated correctly when running "php-cli" instead of just "php" from the command line (or cron).

I discovered that `register_argc_argv` is alway OFF if you use php internal webserver, even if it is set to `On` in the php.ini.

What means there seems to be no way to access argv / argc in php internal commandline server.
