$argv

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.

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).

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

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.
