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.

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 am trying to get a variable from my javascript function while I'm coding in PHP.
my javascript which is included in the page:
function subAmt(empid, subid){
return 4;
}
my attempt to call that function:
$amt = echo "subAmt(3,5);" ;
You need the script tags I think?
echo '<script type="text/javascript">'
, 'subAmt(3,5);'
, '</script>'
;

I am using Yii::app()->user->setState to set some user's session variables.
Is there a way to get the values of them from within JavaScript?
Something like this perhaps? You have to echo it to the JavaScript.
<script>
var myVariable = "<?= Yii::app()->user->getState('myVariable', '') ?>";
alert(myVariable);
</script>
