PHP string to be used in javascript

orangeperson

I've been doing javascript for about a month and gotten fairly good if i do say so myself but I decided I wanted to convert the page I made that does physics projectile problems into php
basically i have this

<html>
<head>
<script type="text/javascript">
function inone(it) { 'use strict'; document.getElementById(it).style.display = 'none'; }
//note that I have many more functions like the one above im just using one as an example
function showY() { 'use strict'; inone('hidCa'); }
</script>
</head>
<body>
<input type="button" onclick="showY()">
</body>
</html>

I would like to know how to put do convert these to php but also for the inone function I would like a generic way to put the php variable created into a javascript command since I have so many similar functions e.g. document.getElementById(it).innerHTML=these;
I was think since the other code for the calculations are so big I would put the php tag write after the script tag and end it right before it closes

It's not really clear what you're trying to do here. PHP is a server-side language while Javascript is a client-side language, so there is no "converting" between the two - they do two very different things.

The site is currently client side, wheni say convert it i mean make it server side. I understand that to modify elements on the page i need to use javascript. I have the showY function called through a onclick event so i need that function to be in javascript. The inone functio will be called mostly in the serverside funtions so i want to make it server side that way i modify the function itself rather than each occurence in the remainder of the file.
Basically it would be somethin like this but correct

<html>
<head>
<script type="text/javascript">
<?php
function inone($it) { 'use strict'; echo"document.getElementById($it).style.display = 'none';"; }
echo"function showY() { 'use strict';"; inone('hidCa'); echo"}";
</script>
</head>
<body>
<input type="button" onclick="showY()">
</body>
</html>
