What are some common methods for automatically resizing images in PHP and saving them with a specific name?

When working with images in PHP, it is common to need to resize them automatically and save them with a specific name. One way to achieve this is by using the GD library, which provides functions for image manipulation. By using functions like imagecreatefromjpeg, imagecopyresampled, and imagejpeg, you can resize an image and save it with a specific name. 

<?php
// Load the original image
$original_image = imagecreatefromjpeg('original.jpg');

// Get the dimensions of the original image
$original_width = imagesx($original_image);
$original_height = imagesy($original_image);

// Calculate the new dimensions for the resized image
$new_width = 200;
$new_height = ($original_height / $original_width) * $new_width;

// Create a new image with the new dimensions
$resized_image = imagecreatetruecolor($new_width, $new_height);

// Resize the original image to the new dimensions
imagecopyresampled($resized_image, $original_image, 0, 0, 0, 0, $new_width, $new_height, $original_width, $original_height);

// Save the resized image with a specific name
$new_image_name = 'resized_image.jpg';
imagejpeg($resized_image, $new_image_name);

// Free up memory
imagedestroy($original_image);
imagedestroy($resized_image);
?>
