How can PHP scripts be optimized to efficiently extract and display information from multiple sources, such as in the case of retrieving data for 33 different parking lots?

To efficiently extract and display information from multiple sources, such as retrieving data for 33 different parking lots, you can use multi-threading or asynchronous processing to fetch data simultaneously from all sources. This can significantly reduce the overall processing time and improve the performance of your PHP script. 

<?php

// List of URLs for the 33 parking lots
$parking_lot_urls = [
    'url1',
    'url2',
    // Add more URLs here
];

// Function to fetch data from a single URL
function fetchData($url) {
    // Code to fetch data from the URL
    // Return the extracted data
}

// Initialize an array to store the fetched data
$fetched_data = [];

// Initialize an array to store the threads
$threads = [];

// Create threads to fetch data from each URL
foreach ($parking_lot_urls as $url) {
    $threads[] = new Thread('fetchData', $url);
}

// Start all threads
foreach ($threads as $thread) {
    $thread->start();
}

// Wait for all threads to finish
foreach ($threads as $thread) {
    $thread->join();
    $fetched_data[] = $thread->getResult();
}

// Display the fetched data
foreach ($fetched_data as $data) {
    // Display the data for each parking lot
}

?>
