How Can I Pass PHP Arrays to JavaScript Functions?

Passing PHP Arrays to JavaScript Functions

When attempting to transfer data from a PHP array to a JavaScript variable, you might encounter difficulties as with your mentioned code. The issue arises because you're trying to pass raw PHP arrays directly to JavaScript, which is not possible.

To address this, the solution is to use JSON (JavaScript Object Notation). JSON allows you to convert PHP data structures into a format that JavaScript can understand and work with.

Modify your code to utilize JSON as follows:

// Encode PHP arrays into JSON
$dayJSON = json_encode($day);
$weekJSON = json_encode($week);
$monthJSON = json_encode($month);

// Pass JSON-encoded data to JavaScript function
drawChart(600/50, <?php echo $dayJSON; ?>, <?php echo $weekJSON; ?>, <?php echo $monthJSON; ?>, /*...*/);

This way, your PHP arrays are converted into JSON strings that JavaScript can deserialize and interpret as objects.

Note: When receiving JSON data from AJAX requests, use JSON.parse() to safely create JavaScript objects from the received JSON string.
