How can PHP code be embedded into JPEG files and executed?

To embed PHP code into JPEG files and execute it, you can use a technique called "steganography." This involves hiding the PHP code within the image file without corrupting the image itself. Once the image is uploaded to a server, the PHP code can be extracted and executed. 

// Embedding PHP code into a JPEG file
$phpCode = "<?php echo 'Hello, World!'; ?>";
$imageFile = 'image.jpg';

// Write the PHP code into the JPEG file using steganography
file_put_contents($imageFile, $phpCode, FILE_APPEND);

// Extract and execute the PHP code from the JPEG file
include $imageFile;
