What is the best approach to display temperature information on an image using PHP?

To display temperature information on an image using PHP, you can use the GD library to overlay text on the image. You can retrieve the temperature information from an API or database and then use the `imagestring()` function to add the text to the image. 

<?php
// Load the image
$image = imagecreatefromjpeg('image.jpg');

// Retrieve temperature information
$temperature = '25°C';

// Set the font size and color
$font_size = 20;
$font_color = imagecolorallocate($image, 255, 255, 255);

// Add temperature information to the image
imagestring($image, 5, 10, 10, $temperature, $font_color);

// Output the image
header('Content-Type: image/jpeg');
imagejpeg($image);

// Free up memory
imagedestroy($image);
?>
