How can PHP developers efficiently handle datetime conversion and JSON formatting for optimal data visualization using Highcharts in PHP applications?

To efficiently handle datetime conversion and JSON formatting for optimal data visualization using Highcharts in PHP applications, PHP developers can use the DateTime class to manipulate dates and times, and then encode the data into JSON format using the json_encode function. 

// Sample data array with datetime values
$data = [
    ['2022-01-01', 10],
    ['2022-01-02', 20],
    ['2022-01-03', 15],
];

// Convert datetime strings to Unix timestamps
foreach ($data as &$row) {
    $row[0] = strtotime($row[0]) * 1000; // Convert to milliseconds for Highcharts
}

// Encode data array into JSON format
$jsonData = json_encode($data);

// Output JSON data for Highcharts
echo $jsonData;
