How can additional variables be passed along with a PHP multi-array to a JavaScript function in PHP applications?

To pass additional variables along with a PHP multi-array to a JavaScript function in PHP applications, you can encode the additional variables as JSON and include them as part of the multi-array. Then, you can access these variables in your JavaScript function by parsing the JSON data. 

<?php
// Define the multi-array with additional variables
$multiArray = array(
    'data' => array(1, 2, 3),
    'additionalData' => json_encode(array('var1' => 'value1', 'var2' => 'value2'))
);

// Encode the multi-array as JSON
$multiArrayJSON = json_encode($multiArray);
?>

<script>
    // Pass the multi-array with additional variables to a JavaScript function
    var multiArray = <?php echo $multiArrayJSON; ?>;
    
    // Access the additional variables in JavaScript
    var additionalData = JSON.parse(multiArray.additionalData);
    console.log(additionalData.var1);
    console.log(additionalData.var2);
</script>
