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;
}

When you pass an option to the file that intercept the request, it will be transformed into an array item, and the option name will be lost. Only its content is captured.

<?php
    var_dump
($argv);
?>

call  :  "php file.php --test=foo baz"

will print

array(3) {
  [0] =>
  string(16) "file.php"
  [1] =>
  string(3) "foo"
  [2] =>
  string(3) "baz"
}

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".

Improves on hamboy75's note by providing better support for positional arguments:

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

    var_dump($_GET);

Using this modification, arguments without an = are treated as positional (this is not web standard but generally works).

If your script is read from standard input or with the -r option, $argv[0] will be "-".

If you use the "--" option to separate PHP's arguments from your script's arguments, $argv[1] will be "--" if your script is read from a file. But if your script is read from standard input or with the -r option, the "--" will be removed.
