试图在同一个html页面上收集和显示访问者的评论

I need your help: I'm trying to gather visitors' comments through a form on an html page and then display them at the bottom of the same html page. I can gather the comments and write them onto a database using a php script, but the comments are displayed on the php page, and not on my original html page. I haven't found any relevant answer in the forums I have visited so far. Your help would be much appreciated.I need your help: I'm trying to gather visitors
