Send a php variable to a different js page

I am facing a little js/php issue. I have 2 different files (a .php one and a .js one containing some scripts the .php page will execute). I would like to send a php variable to the .js page. I looked over the internet but did not find anything that could help me... Thanks for your help !

You can't send php variable directly to js file. For this purpose you have to write php value in a hidden or text field then get that value in js.

You can try to embed the php variable in an hidden input field and try to access that input field in javascript.

 <input type = "hidden" id = "phpvar" value <?php echo $hiddenVar; ?> />
  in javascript 
 var hiddenPhpVar = document.getElementById('phpvar').value;

One solution is to define a JS variable in the HTML (produced by your PHP script):

<script type="text/javascript">
    var SOME_VAR = <?= json_encode($myvariable) ?>;
</script>

I'm using json_encode(), since it will add quotes around strings, and write arrays etc so that it's valid JavaScript.

After that, link the external JS file, in which you can use SOME_VAR with the value that came from PHP.
