How can PHP differentiate between multiple parameters passed in a URL string to avoid confusion or misinterpretation?

PHP can differentiate between multiple parameters passed in a URL string by using the `$_GET` superglobal array. This array contains key-value pairs of parameters passed in the URL. To avoid confusion or misinterpretation, each parameter should have a unique key, and values should be properly sanitized to prevent security vulnerabilities. 

// Example URL: http://example.com/page.php?param1=value1&param2=value2

$param1 = $_GET['param1']; // Accessing the value of param1
$param2 = $_GET['param2']; // Accessing the value of param2

echo "Param1: " . $param1 . "<br>";
echo "Param2: " . $param2;
