What are the potential challenges in generating a GIF87a image with LZW compression using PHP?

One potential challenge in generating a GIF87a image with LZW compression using PHP is the complexity of implementing the LZW compression algorithm. To solve this, you can use a library or package that already has LZW compression functionality built-in, such as the "GifCreator" library in PHP. 

```php
// Example code using GifCreator library to generate a GIF87a image with LZW compression
require_once('GifCreator.php');

// Create a new instance of GifCreator
$gif = new GifCreator();

// Add frames to the GIF
$gif->addFrame($imageData1, 100, true); // Add frame with image data, duration, and transparency
$gif->addFrame($imageData2, 100, true);

// Set the loop count
$gif->setLoop(0); // 0 for infinite loop

// Save the GIF to a file
$gifBinary = $gif->getGif();
file_put_contents('output.gif', $gifBinary);
``` 

Make sure to include the "GifCreator.php" file in the same directory as your PHP script or adjust the path accordingly. This code snippet demonstrates how to use the GifCreator library to generate a GIF87a image with LZW compression in PHP.
