When uploading files using PHP, we will use a program to monitor the file information sent by the browser. First, we will judge whether the status of the file to be uploaded is normal through the different values of $_FILES[fieldName]['error']. $_FILES[fieldName] ['error']==0 means everything is normal. For the specific meaning of other values, please refer to the comment section of the program below!
switch($_FILES[$field]['error']) {
case 1:
// 文件大小超出了服务器的空间大小
break;
case 2:
// 要上传的文件大小超出浏览器限制
$this->setError("The file is too large (form).");
break;
case 3:
// 文件仅部分被上传
$this->setError("The file was only partially uploaded.");
break;
case 4:
// 没有找到要上传的文件
break;
case 5:
// 服务器临时文件夹丢失
break;
case 6:
// 文件写入到临时文件夹出错
break;
}
