Slow php function (i need Async func)

Question

Hello my sololearn.
I have an php website and when the user submitted the form the data move to tge database. And it's okay.

But when i setup an SMTP so i can get copy of the entered data to my email too. But it's so slow. It takes about 4 seconds and that's a very BIG TIME NUMBER.
I want just to run php function without reloading the page.

So is there anyway to run functions on the server ? I mean hosting server not user server side.

Or any way to just run php function from another page without making it run on my main page, because i tried the include func.

Thanks !

Answer 1

sending email from php SMTP! without reloading!
You have to use Ajax in JS or axios for (React /Vue)
this will save your time without reloading the entire page
