How can PHP developers optimize their code for extracting and storing image URLs from a specific domain like Zalando?

To optimize code for extracting and storing image URLs from a specific domain like Zalando, PHP developers can use regular expressions to search for image URLs within the HTML content of the website. By using a combination of functions like file_get_contents() to fetch the website content and preg_match_all() to extract image URLs, developers can efficiently collect and store the desired URLs. 

<?php

// URL of the website to extract image URLs from
$url = 'https://www.zalando.com';

// Fetch the HTML content of the website
$html = file_get_contents($url);

// Regular expression to match image URLs
preg_match_all('/<img[^>]+src="([^">]+)"/', $html, $matches);

// Store the extracted image URLs in an array
$imageUrls = $matches[1];

// Output the extracted image URLs
print_r($imageUrls);

?>
