在PHP中上载多个文件时无法检查文件大小

我正在尝试检查多个文件上载的文件大小限制。每次我收到抱歉，您的文件上载过大，最大文件大小为10 MB。 无法找出错误

没有提供文件限制，文件上传工作正常。我还在PHP.ini文件中做了必要的更改，如POST_MAX_SIZE和MAX_file_SIZE，但响应是相同的

foreach($_FILES['upload_slider']['tmp_name'] as $key => $tmp_name){
                #file upload size - file size 10MB
                $fileSize = $_FILES['upload_slider']['size'][$key];
                if ($fileSize <= 10485760) #10 MB 
                {

                    $_SESSION['upload_warning'] = "Sorry, your file is too large upload, maximum file size is 10 MB.";
                    header("location:../slider.php");
                    die;            
                }


            else{
                $file_name = strtolower($_FILES['upload_slider']['name'][$key]);
                $file_tmp = $_FILES['upload_slider']['tmp_name'][$key];
                $ext = pathinfo($file_name, PATHINFO_EXTENSION);
                $new_filename = rand().".".$ext;
                if(in_array($ext,$extension))
                {
                    move_uploaded_file($file_tmp= $_FILES['upload_slider']['tmp_name'][$key],"$album_dir$new_filename");
                    # insert record in database

                    $values = [
                    'slider_id' =>$slider_id,
                    'image_name' => $new_filename,
                    //'album_name' => $album_title,
                    'image_path' => $db_album_dir.$new_filename,
                    'uploaded_date' => date("Y/m/d h:i:s ")
                    ];
                    $res = $abc->insert($tablename,$values);                
                    header("location:../slider.php");
                }
                else
                {
                    $_SESSION['upload_warning'] = "Please upload appropriate file type extension i.e. <b> jpg, jpeg, png , gif. </b> ";
                    header("location:../slider.php");
                    die;
                }
            }

        }//EOF FROEACH

您是否试图将每个文件限制为10Mb？因为现在你的if声明正好相反：

if ($fileSize <= 10485760){ //if the file is less or equal to 10mb
//return error
}
else{ //else if the file is larger than 10mb
//proceed with uploading
}

这是什么类型的运算符=>？对不起，我犯了一个错误，我的意思是写>=大于或等于，但写了=>这是关联数组的分隔符。现在已在邮件中修复。关联数组如下所示：$user_list=数组'name'=>john'、'姓氏'=>white'；在本例中，它不是索引号0-n，而是“键”，即分配给值john，white的名称和姓氏。

if($fileSize >= 10485760){ //return error
}
else { //upload file
}
