php - 如何为按名称上传文件制作区分大小写的代码

Question

所以我有不止一张图片要上传，每一张都是我的 mysql 表中的一个新行:

我将此代码用于 name="profile"的文件输入

if (isset($_FILES['profile']) === true) {
if (empty($_FILES['profile']['name']) === true) {
    echo 'Please choose a file!';
}else {
    $allowed= array('jpg', 'jpeg', 'png')       
    $file_name = $_FILES['profile']['name'];
    $file_exts = explode('.', $file_name);
    $file_extn = strtolower(end($file_exts));
    $file_temp = $_FILES['profile']['tmp_name'];
    if (in_array($file_extn, $allowed) === true) {
        change_image($session_user_id, 1, $file_temp, $file_extn);
        header('Location: galery.php');
        exit();
    }else {
        echo 'Incorrect file type . allowed files are : ';
        echo implode(", ", $allowed);

(change_image) 函数生成这个 MySql 查询

$sql = "UPDATE `art_$id` SET `path` = \"" . $file_path . "\" WHERE `row` = " . (int)$row;

但我想为 profil1、profil2...重复此代码并相应地更改行(例如:profil4 将更改第 4 行)，而不必为每个 file='name' 重复此代码。

我该怎么做？

无论您的表单有多少个字段以及它们的名称？？ .下面的代码会一一上传..检查一下

 $rowid=1;
    foreach($_FILES as $key=>$image_uploaded)
    {
    if (isset($image_uploaded[$key]) === true) {
    if (empty($image_uploaded[$key]['name']) === true) {
        echo 'Please choose a file!';
    }else {
        $allowed= array('jpg', 'jpeg', 'png')       
        $file_name = $image_uploaded[$key]['name'];
        $file_exts = explode('.', $file_name);
        $file_extn = strtolower(end($file_exts));
        $file_temp = $image_uploaded[$key]['tmp_name'];
        if (in_array($file_extn, $allowed) === true) {
            change_image($session_user_id, $rowid++, $file_temp, $file_extn);
            //change as you need
            header('Location: galery.php');
            exit();
        }else {
            echo 'Incorrect file type . allowed files are : ';
            echo implode(", ", $allowed);
    }
