else $fileImg=$_FILES[&#39;upfile&#39;];
switch($fileImg[&#39;Error&#39;]){
case 1:

break;
case 3:

break;
case 4:
$err_msg=&#39;没有选择文件&#39;.$err_msg_behind;
break;
case 2:
$err_msg=&#39;文件超过页面最大上传限制&#39;.$err_msg_behind;
break;
case 7:
$err_msg=&#39;文件写入失败&#39;.$err_msg_behind;
break;
case 6:
$err_msg=&#39;没有临时文件夹&#39;.$err_msg_behind;
break;
case 0:
break;
default:
$err_msg=&#39;未知错误&#39;.$err_msg_behind;
}
if (!in_array($fileImg[&#39;type&#39;],array(&#39;image/jpeg&#39;,&#39;image/pjpeg&#39;,&#39;image/png&#39;))) $msg="只允许上传png或jpg图片".$err_msg_behind;
if (!$err_msg){
if (!move_uploaded_file($fileImg[&#39;temp_name&#39;],$dir.$fileImg[&#39;name&#39;])){
$err_msg=&#39;移动文件失败&#39;.$err_msg_behind;
}
}
if ($err_msg) error ($err_msg);
else{
echo &#39;完成&#39;;
}
include("../Include/Close.php");
?>

Solution:

if (!move_uploaded_file($fileImg['temp_name'],$dir.$fileImg['name'])){
$err_msg='移动文件失败'.$err_msg_behind;
}

move_upload_file cannot move the file

1. Please confirm whether the file path of $dir.$fileImg['name'] is correct.

$dir=$file_upload_root.'HeadImages' Whether you need to add "/" at the end

2. Please Make sure $dir has writable permission
