There are actually several approaches to do this:

 

    Use AJAX to get the data you need from the server.

    Consider get-data.php:

 

echo json_encode(42);

 

Consider index.html:

 

<script>

    function reqListener () {

      console.log(this.responseText);

    }

 

    var oReq = new XMLHttpRequest(); // New request object

    oReq.onload = function() {

        // This is where you handle what to do with the response.

        // The actual data is found on this.responseText

        alert(this.responseText); // Will alert: 42

    };

    oReq.open("get", "get-data.php", true);

    //                               ^ Don't block the rest of the execution.

    //                                 Don't wait until the request finishes to

    //                                 continue.

    oReq.send();

</script>

 

    Echo the data into the page somewhere, and use JavaScript to get the information from the DOM.

 

<div id="dom-target" style="display: none;">

    <?php

        $output = "42"; // Again, do some operation, get the output.

        echo htmlspecialchars($output); /* You have to escape because the result

                                           will not be valid HTML otherwise. */

    ?>

</div>

<script>

    var div = document.getElementById("dom-target");

    var myData = div.textContent;

</script>

 

    Echo the data directly to JavaScript.

 

<script>

    var data = <?php echo json_encode("42", JSON_HEX_TAG); ?>; // Don't forget the extra semicolon!

</script>
