How can PHP scripts handle command line arguments effectively?

PHP scripts can handle command line arguments effectively by using the built-in $argv variable which contains an array of all the arguments passed to the script. The $argc variable can be used to determine the number of arguments passed. By parsing and validating these arguments, scripts can perform different actions based on the input provided. 

<?php
// Check for the number of arguments passed
if ($argc < 2) {
    echo "Usage: php script.php <argument>\n";
    exit(1);
}

// Retrieve the argument from $argv array
$argument = $argv[1];

// Perform actions based on the argument
if ($argument === 'option1') {
    echo "Option 1 selected\n";
} elseif ($argument === 'option2') {
    echo "Option 2 selected\n";
} else {
    echo "Invalid argument\n";
}
