if ($_FILES['upload']['error'] === UPLOAD_ERR_INI_SIZE) {
    // Error: File exceeds upload_max_filesize directive in php.ini
}

; ✅ Increase upload limits in php.ini
upload_max_filesize = 64M

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    if ($_FILES['upload']['error'] === UPLOAD_ERR_INI_SIZE) {
        die('File too large. Maximum size: ' . ini_get('upload_max_filesize'));
    }
    
    // ✅ Process upload
    $file = $_FILES['upload'];
    move_uploaded_file($file['tmp_name'], 'uploads/' . $file['name']);
