I am an amateur php coder at best, yet I muddle through and make stuff work mostly, So this is not crashing, but all I am getting as an answer is the header and my this is not working, what am I doing wrong here? The fact that it is not throwing up an error is already a win, I have checked, $content exists.

 

<?php
function validateURL($url) {
    return filter_var($url, FILTER_VALIDATE_URL);
}

function fetchURLContent($url) {
    $content = @file_get_contents($url);
    return $content !== false ? $content : false;
}
function analyzePage($url) {
    $analysis = [];

    $url = validateURL($url);
    if ($url) {
        $content = fetchURLContent($url);

        if ($content !== false) {
            $analysis['page_size'] = getPageSize($content);
            //$analysis['page_speed'] = getPageSpeed($url);
        }
    }
}

function getPageSize($content) {
    // Example: Calculate and return the page size
    return number_format(strlen($content) / 1024, 2) . ' KB';
}

/*function getPageSpeed($url) {
    // Example: Calculate and return the page load time
    $start_time = microtime(true);
    $content = fetchURLContent($url);
    $end_time = microtime(true);

    $load_time = ($end_time - $start_time) * 1000;
    return number_format($load_time, 2) . ' ms';
}

function getPageRequests($content) {
    // Example: Count and return the number of page requests
    preg_match_all('/<img [^>]*src=["\']([^"\']+)["\']/i', $content, $images);
    return count($images[1]);
}
*/

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $url = $_POST['url'];
    $analysis = analyzePage($url);

    if (isset($analysis['error'])) {
        echo "<p>Error: {$analysis['error']}</p>";
    } else {
        // Output analysis results here...
        echo "<h1>Test</h1>";
        foreach ($analysis as $key => $value) {
            echo "<p>$key: $value</p>";
        }
    }



echo "This shit is working but not";
    }
    else
    {
?>

<h1>Test</h1>
    <form method="post">
        <label for="url">Enter URL: </label>
        <input type="text" name="url" id="url" required>
        <input type="submit" value="Analyze">
    </form>

    <?php
    }
    ?>

Your analyzePage function is not returning a value, so your $analysis variable will be null.  If you have PHP's error reporting turned up all the way, and are on a modern version of PHP, you should be seeing a warning about not being able to use foreach on a null value.

On an unrelated note:

This could simply be return $content; There is no need for the check against false there since if it is false, you will just return false.
