What is the recommended approach for embedding PHP code for image generation within an HTML file?

When embedding PHP code for image generation within an HTML file, it is recommended to use the PHP opening and closing tags within the HTML file. This allows the PHP code to be executed on the server-side before the HTML is rendered, ensuring that the image is generated correctly.

<?php
// PHP code for image generation
$image = imagecreate(200, 200);
$bg_color = imagecolorallocate($image, 255, 255, 255);
$text_color = imagecolorallocate($image, 0, 0, 0);
imagestring($image, 5, 50, 80, 'Generated Image', $text_color);
header('Content-type: image/png');
imagepng($image);
imagedestroy($image);
?>
