我想在我的网站上发布一些图片。
当我只使用一张图片时，它适用于单个帖子。因为我试图使用多个图像它不再工作，我不明白为什么这不起作用。显示我的代码：

还有办法缩短这段代码吗？非常感谢。

你这么做错了。为您的代码提供更多冗余
$allowed_extension = array('jpg', 'jpeg', 'png', 'bmp', 'tiff', 'gif');
foreach($_FILES as $file) {
// Carry on like this
$file_name = $file['name'];
$size = $file['size'];
//However, you might want to extract the extension like this
$ext = pathinfo($file_name, PATHINFO_EXTENSION);
//...
}
