I have to validate 3 input file, any idea or guidance to improve my code ?

I was thinking to validate it using jquery

if (empty($_FILES['docmuent_1']) && !isset($_FILES('document_2']) && !isset($_FILES('document_3']) {

   echo json_encode(array(

       'error' => true,

       'message' => 'The document is incorrect, Please select .excel, .word, .jpg, .png'

    ));

} else {

   move_uploaded_file($_FILES['document_1']['tmp_name'], $_SERVER["DOCUMENT_ROOT"] . 'mdh/files/ . $_FILES['document_1'] ['name]);

        }



if (empty($_FILES['document2']) && !isset($_FILES['document_3])  ) {

    echo json_encode(array(

        'error' => true,

        'message' => 'The document is incorrect, Please select .excel, .word, .jpg, .png'

    ));

} else {

  move_uploaded_file($_FILES['document_2']['tmp_name'], $_SERVER["DOCUMENT_ROOT"] . 'mdh/files/ . $_FILES['document_2'] ['name]);



        }

My Answer:
{
if (empty($_FILES['document_1']) || empty($_FILES['document_2']) || empty($_FILES['document_3'])) {
echo "Please upload all 3 documents.";
} else {
// Validate file types and sizes
$allowedTypes = ['pdf', 'doc', 'docx'];
$maxSize = 5 * 1024 * 1024; // 5MB

foreach ($_FILES as $file) {
$fileType = pathinfo($file['name'], PATHINFO_EXTENSION);
$fileSize = $file['size'];

if (!in_array($fileType, $allowedTypes)) {
echo "Invalid file type for " . $file['name'];
} elseif ($fileSize > $maxSize) {
echo "File size exceeds limit for " . $file['name'];
} else {
// File is valid, do something with it
}
}
}
}
