Transferring an Array from PHP to Javascript

I'm attempting to pass a PHP array so that I can use it in JavaScript.

The PHP code I have written is shown below:

<?php

$link = mysqli_connect("localhost", "root", "password", "database");

    /* check connection */
    if (mysqli_connect_errno()) {
        printf("Connect failed: %s\n", mysqli_connect_error());
        exit();
    }

    $query = "SELECT * FROM Employees";

    if ($result = mysqli_query($link, $query)) {

        /* fetch associative array */
        while ($row = mysqli_fetch_assoc($result)) {

            $data[] = $row;
        }
        print_r($row);
        /* free result set */
        mysqli_free_result($result);
    }
    /* close connection */
    mysqli_close($link);

//convert the PHP array into JSON format, so it works with javascript
$json_array = json_encode($data);
?>

JavaScript:

<script> 
    var array = <?php echo $data; ?>; 
    console.log(array); 
</script>

Unfortunately, it seems like the data array from PHP is not being successfully transferred to the Javascript variable array. The Firebug console displays the following error messages:

Notice - Array to string conversion.

If anyone has any insights on why this problem is happening, your help would be greatly appreciated.

Answer №1

It's possible that the issue is arising because you are outputting the array directly instead of encoding it into a JSON string.

Try this alternative solution:

<script> var data = <?php echo $json_data; ?>;
console.log(data); </script>

Answer №2

Here is a possible solution:

<script>
var data = <?php echo $json_array; ?>;
console.log(data);
</script>

It seems like you are encoding the data as JSON in the variable $data but not using it in your code. Perhaps that is causing the issue?
