Are there any specific PHP functions or libraries recommended for creating temperature graphs with date and time information?

To create temperature graphs with date and time information in PHP, you can utilize libraries such as Chart.js or Google Charts. These libraries provide easy-to-use functions for generating interactive and visually appealing graphs. Additionally, you can use PHP functions like strtotime() to convert date and time strings into Unix timestamps for plotting on the graph. 

<?php
// Sample data for temperature and date/time
$data = [
    ['2022-01-01 08:00:00', 20],
    ['2022-01-01 09:00:00', 22],
    ['2022-01-01 10:00:00', 25],
    // Add more data here
];

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

// Encode data as JSON for use in Chart.js or Google Charts
$data_json = json_encode($data);

// Output JSON data for use in JavaScript
echo "var temperatureData = $data_json;";
?>
