I need to add JavaScript variable to PHP array, my code is below and var date1 is JavaScript variable.
Code
$date1="2018-08-02";
$date=explode("-",$date1);
My JavaSript section is here
var date1=new Date(<?=$date[0].",".$date[1].",".$date[2]?>);
date1 place to index of array x
$incoming[$i] = array("x" =>+date1 , "y" => $total_inc);
$outgoing[$i] = array("x" => +date1, "y" => $total_out);
In this situation the value is return 0.
You can't. JS code is executed after PHP finished executing own code. You can pass data from js to php by ajax or by setting a cookie.

I'm trying to select a specific audio element based on the key that's pressed. The issue is the compiler is reading the variable as a string. How can I get it to read it as a variable?
var hail = e.keyCode
var afile = document.querySelector("audio[data-id='hail']")
You can use Javascript template strings :
var hail = e.keyCode
var afile = document.querySelector(`audio[data-id=${hail}]`)

Is that possible to pass a JS variable to PHP ?
My code is :
document.getElementById('designation_' + i).value = '<?php echo $list[HERE]; ?>';
where I is in a for loop.
I want to echo the $list array in PHP with the index I of my JS (instead of HERE).
First, is that possible? If yes, how?
You can not pass the JavaScript variable up to PHP to index the $list array. What you can do is to pass the whole array down to JavaScript as JSON encoded and then index into that.
