How important is it to consider image quality and aspect ratio when resizing images in PHP?

When resizing images in PHP, it is crucial to consider image quality to ensure that the resized image maintains its clarity and sharpness. Additionally, aspect ratio must be maintained to prevent distortion or stretching of the image. These factors play a significant role in the overall visual appeal and professionalism of the resized image. 

// Load the original image
$originalImage = imagecreatefromjpeg('original.jpg');

// Define the desired width and height for the resized image
$width = 400;
$height = 300;

// Create a new image with the desired dimensions
$resizedImage = imagecreatetruecolor($width, $height);

// Resize the original image to fit the new dimensions
imagecopyresampled($resizedImage, $originalImage, 0, 0, 0, 0, $width, $height, imagesx($originalImage), imagesy($originalImage));

// Output the resized image with specified quality
imagejpeg($resizedImage, 'resized.jpg', 90);

// Free up memory
imagedestroy($originalImage);
imagedestroy($resizedImage);
