PHP页面显示空白页面和本地相同的脚本下载页面

Question

I have a website on php, a Month Before it was working fine but Now i am facing an My Website is Not Loading, I hadn't Change Any thing. After This issue Reported I applied error reporting Lines in PHP File But its Not showing the Errors. so I downloaded the Whole Project and Runs That in Local. but in Local , WHen i Run PHP Script For only this Website it Downloads the Page every time. on Local I tried other script from any other page its working But Not on the web which is giving Issue.

Similarly The Web which is not Working right now. i have an Old Backup so i tried that too to run on local that backup is also doing the same issue.

Answer 1

i got the Solution, The Problem was obsoleted Mysql Connection, as the Website was Created in 2014 on mysql Connection. For finding the Solution. I Removed All PHP Code First and Tried to Place The Code Lines One by One. and Then i got to the Solution that All Functions of PHP to SQL were on mysql which was the Issue, i converted All Functions in PDO and its working fine.
