php文件在本地服务器上工作，但在联机服务器上失败

Question

I did complete a website for online Entrance form for students as my demo project to learn. 我确实完成了一个用于学生在线入学申请表的网站，作为我要学习的演示项目。 When I run from my local server it works fine but when I uploaded on webserver and tasted index.php and other files run fine except when user enter his/her symbol no to check if he/she already been registered or not..I have coded a logic 当我从本地服务器运行时，它可以正常工作，但是当我在网络服务器上上传并品尝到index.php和其他文件时，除了用户输入他/她的符号no来检查他/她是否已经注册外，其他文件都运行正常。编码逻辑

if (exists)>Show admit card if(don't exist)>show alert box 如果（存在）>显示入场卡，如果（不存在）>显示警报框

It works fine in local server but in webserver when I enter value in search box and enter then it shows empty page with no any error. 当我在搜索框中输入值并输入然后显示空白页时，它在本地服务器上运行良好，但在Web服务器中运行，没有任何错误。

I have one row in my database. 我的数据库中有一行。 So in case you wanna check here is the symbol no in column =15369-2017-02 . 因此，如果您想在此处检查= 15369-2017-02列中的符号no。 On Entering submit it should show admit card and you can enter any random value other then this .which should show alert box. 在输入提交时，它应该显示准入卡，您可以输入除此以外的任何随机值，它应该显示警报框。

Here is my website 这是我的网站

It seems that your php is not executed correctly. 看来您的php执行不正确。 Maybe try to enable error reporting to get a hint of what's wrong. 也许尝试启用错误报告以获取错误提示。

Include the following at the beginning of your destination file (my.php) 在目标文件（my.php）的开头包含以下内容

<?php
error_reporting(E_ALL);
ini_set("display_errors", 1);
