What are some common pitfalls to avoid when resizing images in PHP?

One common pitfall to avoid when resizing images in PHP is not maintaining the aspect ratio of the image. This can result in distorted images that do not look visually appealing. To solve this issue, you can calculate the aspect ratio of the original image and then use it to resize the image proportionally. 

// Calculate aspect ratio
$originalWidth = imagesx($originalImage);
$originalHeight = imagesy($originalImage);
$aspectRatio = $originalWidth / $originalHeight;

// Resize image proportionally
$newWidth = 200; // New width you want
$newHeight = $newWidth / $aspectRatio;

$newImage = imagecreatetruecolor($newWidth, $newHeight);
imagecopyresampled($newImage, $originalImage, 0, 0, 0, 0, $newWidth, $newHeight, $originalWidth, $originalHeight);
