How can the process of resizing images locally before uploading them be achieved using PHP?

Resizing images locally before uploading them can be achieved using PHP by utilizing the GD library, which provides functions for image manipulation. By using functions like imagecreatefromjpeg(), imagecopyresampled(), and imagejpeg(), you can resize an image to the desired dimensions before uploading it. 

// 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);

// Set the desired width and height for the resized image
$desired_width = 500;
$desired_height = 300;

// Create a new image with the desired dimensions
$resized_image = imagecreatetruecolor($desired_width, $desired_height);

// Resize the original image to fit the new dimensions
imagecopyresampled($resized_image, $original_image, 0, 0, 0, 0, $desired_width, $desired_height, $original_width, $original_height);

// Save the resized image to a file
imagejpeg($resized_image, 'resized.jpg');

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