In terms of performance and efficiency, would it be better to use regular expressions, sscanf, or explode functions to extract and process data from URLs in PHP scripts?

When extracting and processing data from URLs in PHP scripts, using regular expressions can provide the most flexibility and power, but it may come at the cost of performance. sscanf is a simpler alternative that can be more efficient for basic pattern matching. Explode functions are the easiest to use but may not be as robust as regular expressions or sscanf.

// Example using regular expressions to extract data from a URL
$url = "https://www.example.com/products/123";
preg_match('/\/products\/(\d+)/', $url, $matches);
$product_id = $matches[1];
echo $product_id;
