Question

我使用下面的代码来上传和调整多个图像的大小。

如果我选择大约10-20个图像，一切正常，但如果我选择50个或更多图像，没有任何反应，页面只会在几秒钟后重新加载。

代码有问题，或者ini文件或服务器配置中的最大文件大小是否有限？

if(isset($_POST['submit']))
{
    if(isset($_FILES['gallery']))
    {
        foreach($_FILES['gallery']["name"] AS $key=>$file)
        {
            if($_FILES['gallery']['size'][$key]  != 0 )
            {
                $ThumbSquareSize        = $gallery_thumb_size;
                $BigImageMaxSize        = $gallery_big_size;
                $ThumbPrefix            = "th-";
                $DestinationDirectory   = '../images/gallery/';
                $Quality                = $imgQuality;
                if(!is_uploaded_file($_FILES['gallery']['tmp_name'][$key]))
                {
                    $error[] = "Elképzelhető, hogy nem választott ki fényképet.";
                }

                $RandomNumber   = $id.'-'.rand(0, 99999999);

    }
}

Answer 1

在php.ini中更新此设置

memory_limit = 256M
upload_max_size = 64M
post_max_size = 64M
upload_max_filesize = 64M
max_execution_time = 300
max_input_time = 1000

然后重新启动服务器，通过浏览器检查php.ini中的更新更改，然后上传图像，如果再次出现问题，则将此值增加到更大。

Answer 2

最大文件大小限制为128兆字节（或可根据要求进行更改）。在变量

下检查php.ini

upload_max_filesize = **
post_max_size = **

当我选择许多图像时，Php多图像上传失败
