Can I pop up alert in javascript using php

Question

I want to trigger javascript alert using PHP. Is it possible

I want to use it in head section, for displaying it at load time.

Answer 1

Of course this is possible.

All you are doing is outputting JavaScript, it's all the same thing.

The only issue is that you are nesting

By the way, as i'm sure you already know, this specific code will ALWAYS echo the "alert('Hi');"
