Question

我尝试实现文件上传器+ mysqli数据插入。

该脚本使用PHP函数move_uploaded_file和mysqli_connect，并在move_uploaded_file返回成功时完美运行。

但是当move_uploaded_file因连接问题或用户取消而失败时，处理mysqli请求大约需要12分钟。

问题是：

如果很多用户取消他们的上传，我的服务器将会加载待处理的请求吗？

我正在尝试立即处理第一个Mysqli请求，它有效，但是只要我添加move_uploaded_file函数并导致客户端失败，它的行为就像描述的那样。

到目前为止，这是PHP代码：

if (isset($_POST['captcha']) AND ($_POST['captcha'] == '*')){
        $id_link = mysqli_connect($db_host,$db_user,$db_pass,$db_name) or die("Error " . mysqli_error($id_link));
        $currenttime = time();
        $uniqueId = rand(1000, 9999);
        $time = $currenttime . 'pr' . $uniqueId ;
        $name = addslashes($_POST['name']);
        $surname = addslashes($_POST['surname']);
        $email = addslashes($_POST['email']);
        $fileName = addslashes($_FILES["file"]["name"]);
        $query = "INSERT INTO `mydb`.`mytable` (`date`, `name`, `surname`, `email`, `file`, `uploaddone`) VALUES ('". $time ."', '" . $name . "', '" . $surname . "', '" .$email . "', '" . $fileName . "', '0');";
        $result = $id_link->query($query) or die("Error in the consult.." . mysqli_error($id_link));
        if (isset($_FILES['file']) AND $_FILES['file']['error'] == 0){
            $fileTmpLoc = $_FILES["file"]["tmp_name"]; // File in the PHP tmp folder 
            $fileType = $_FILES["file"]["type"]; // The type of file it is 
            $fileSize = $_FILES["file"]["size"]; // File size in bytes 
            $fileErrorMsg = $_FILES["file"]["error"]; // 0 for false... and 1 for true
            if ($fileSize <= 200000000){
                $infosfile = pathinfo($fileName);
                $extension_upload = $infosfile['extension'];
                $extensions_allowed = array('jpg', 'jpeg', 'gif', 'png' , 'mov' , 'avi' , 'mp4' , 'mpeg4' , 'MPEGPS' , 'MPEG4' , 'FLV' , 'flv' , 'WMV' , 'wmv' , '3GPP' , '3gpp' , 'WebM' , 'mp2' , 'mpeg2' , 'MPG' , 'm4v' , 'pdf' , 'MOV' , 'AVI' , 'MP4' , 'M4V' , 'PNG' , 'PDF' , 'JPEG' , 'JPG' , 'GIF', 'tif' , 'tiff' , 'TIF' , 'TIFF','mkv' , 'dv' , 'mts' , 'qt' , 'ogv' , 'ts' , 'vob' , 'mpeg' , 'mpe' , 'f4v' , 'dat' , 'divx' , 'asf' , '3g2' , '3gp', 'MKV' , 'DV' , 'MTS' , 'QT' , 'OGV' , 'TS' , 'VOB' , 'MPEG' , 'MPE' , 'F4V' , 'DAT' , 'DIVX' , 'ASF' , '3G2' , '3GP');
                if (in_array($extension_upload, $extensions_allowed)){
                    if (!$fileTmpLoc) { // if file not chosen 
                        echo "ERROR: Please browse for a file before clicking the upload button."; 
                        exit(); 
                    }
                //check if file exist and rename it
                $newname = $fileName;
                $filenamecheck = 'upload/' . $newname;
                    if ($pos = strrpos($fileName, '.')) {
                        $name = substr($fileName, 0, $pos);
                        $ext = substr($fileName, $pos);
                    } else {
                       $name = $fileName;
                    }
                    $counter = 2;
                    while (file_exists($filenamecheck)) {       
                        $fileName = $name .'-'. $counter . $ext;
                        $filenamecheck = 'upload/' . $fileName;
                        $counter++;
                    }
                    if(move_uploaded_file($fileTmpLoc, "upload/$fileName")){
                        $query= "UPDATE `mydb`.`mytable` SET `file` = '" . $fileName . "',`uploaddone` = '1' WHERE `mytable`.`date` =" . $time;
                        $result = $id_link->query($query) or die("Error in the consult.." . mysqli_error($id_link));
                        die('{"error" : false, "message" : "Congratulations your upload is complete<br>you can now<br>"}');
                    } else {
                        die('{"error" : true, "message" : "Sorry Network Issue"}');
                    }
                }else{
                    die('{"error" : true, "message" : "Sorry wrong file format"}');
                }       
            }else{
                die('{"error" : true, "message" : "File too big"}');
            }
        }
    }else{
        die('{"error" : true, "message" : "Please answer the security question before uploading"}'); 
    }

我尝试了很多不同的解决方案（php标头删除缓存，关闭并重新打开msqli请求）但到目前为止没有任何工作，

如果你们有任何想法，那么信条会非常好，

非常感谢！
