You just have to write it. There's no magic bullet. Although you could google for a php to javascript converter but I doubt it would even work well, if at all.

This is not a code conversion service: we are not here to translate code for you.
Even if we did, what you would end up with would not be "good code" in the target language – they are based on very different frameworks, and what makes something work in one language does not always "translate" directly into another.
So what you end up with is very poor code, that is difficult if not impossible to maintain, that can’t be upgraded nicely, and that will cause you immense headaches if the original is changed. And it’ll be a nightmare to debug if it doesn’t work "straight out of the box".
Instead, use the source code as a specification for a new app written in and for the target language / framework and write it from scratch using the original as a "template". You will get a much, much better result that will save you a lot of time in the long run.

And converting Server side code to Client side? That isn't going to work at all, even if the two languages were identical!

Bite the bullet: sit down, think, design, and then write the code to do the task in JS. It really is the only way.

You can't. You need to rewrite code. Because PHP is server-side language & Js is client-side language.

But you can use it together. Learn both JavaScript[^] & PHP[^]. Then start doing rewrite.

Here a sample simple website using both Js & PHP
