What are some best practices for handling empty entries in a PHP array when generating charts?

When generating charts with PHP, empty entries in an array can cause issues such as gaps in the chart or incorrect data representation. To handle empty entries, a best practice is to filter out these entries before generating the chart to ensure accurate data visualization. 

// Sample PHP code snippet to handle empty entries in an array before generating a chart

$data = [10, 20, null, 30, '', 40]; // Sample data array with empty entries

// Filter out empty entries from the data array
$data = array_filter($data, function($value) {
    return $value !== '' && $value !== null;
});

// Use the filtered data array to generate the chart
// Code to generate chart using $data
