如何讓 PHP 取得 Command Line 的參數

<?php
function arguments($argv) {
    $ARG = array();
    $n = count($argv);
    for ($i = 0; $i < $n ; $i++) {
        $val = $argv[$i];
        if (preg_match('/^[-]{1,2}([^=]+)=[s]*([^s]+)/', $val, $match)) {
            $ARG[$match[1]] = $match[2];
        } else if (preg_match('/^[-]{1,2}([^=s]+)$/', $val, $match)) {
            $i++;
            $ARG[$match[1]] = $argv[$i];
        }
    }
    return $ARG;
}
 
$argv = arguments($_SERVER['argv']);
print_r($argv);
/*
array(
  "source" => "./src",
  "destination" => "../result"
)
*/
