Note Just tell me a solution,When I test the above code on window xp, it will run correctly and i upload up to 103kb file, but it will not work on window 8, and create problem like I mention above... is the Xammp latest version have bugs, or what is the problem?注意只是告诉我一个解决方案，当我在 windows xp 上测试上述代码时，它会正确运行并且我上传了最多 103kb 的文件，但它在 windows 8 上不起作用，并且会产生我上面提到的问题......是Xammp 最新版本有bug，还是什么问题？
Note The error is not the code, the error is logical, so please be specific and to the point.注意错误不是代码，错误是合乎逻辑的，所以请具体点。 Please add the explanatory answer....请添加解释性答案....

As @Shikata wrote, be careful with:正如@Shikata 所写，请注意：
$TARGET_PATH = "images/";
$image['name'] =$image['name'];
$TARGET_PATH .= $image['name'];
Instead just use:而只是使用：
$TARGET_PATH = "images/".$image['name'];
And like the other answers, you must check the validation!和其他答案一样，您必须检查验证！ Also erase the strar_session();同时擦除 strar_session(); from connection.php来自 connection.php
Also as sugestion try to check PDO prepared-statements http://php.net//manual/en/pdo.prepared-statements.php (I really suggest reading this, please give it a try, it can give you a more secure way to implement queries by binding parameters and by that way avoiding some SQL injections problems)另外作为建议尝试检查 PDO 准备好的语句http://php.net//manual/en/pdo.prepared-statements.php （我真的建议阅读这个，请试一试，它可以给你一个更安全的通过绑定参数来实现查询的方法，从而避免一些 SQL 注入问题）
(Sorry for not going to the point with the previous answer) That's about the code, as much as I try it (few time), about the upload problem maybe checking the upload_max_filesize and post_max_size . （抱歉，我没有在前面的答案中指出这一点）这是关于代码，尽管我尝试过（很少），关于上传问题，可能会检查upload_max_filesize和post_max_size 。 If the problem is still there try checking max_input_time and max_execution_time .如果问题仍然存在，请尝试检查max_input_time和max_execution_time 。 I hope you get a solution.我希望你得到一个解决方案。

may be its file permission error可能是它的文件权限错误
in linux open terminal and enable file permission在linux中打开终端并启用文件权限
chmod -R 777 /var/www/html/folder_name (or your path)
to disable :-禁用：-
chmod -R 775 /var/www/html/folder_name
or go to your file>right click >change permission from read only to read and write或转到您的文件>右键单击>将权限从只读更改为读写

尝试在您的 wamp 或 xamp 文件夹中搜索 my.ini 并将 max_allowed_packets 编辑为更大的尺寸。谢谢
