How can PHP scripts be structured to efficiently process and save uploaded images on the server?

To efficiently process and save uploaded images on the server in PHP, you can use the following approach: 1. Use the move_uploaded_file function to move the uploaded image file to a specified directory on the server. 2. Use image processing functions like imagecreatefromjpeg, imagecreatefrompng, etc., to manipulate the image if needed. 3. Save the processed image using functions like imagejpeg, imagepng, etc., to store it in the desired format and quality. 

<?php
if(isset($_FILES['image'])){
    $file_name = $_FILES['image']['name'];
    $file_tmp = $_FILES['image']['tmp_name'];
    
    $upload_path = 'uploads/' . $file_name;
    
    if(move_uploaded_file($file_tmp, $upload_path)){
        // Image processing code here if needed
        
        // Save the processed image
        // For example, saving as JPEG
        $image = imagecreatefromjpeg($upload_path);
        imagejpeg($image, 'processed/' . $file_name, 80); // Save with 80% quality
        
        // Free up memory
        imagedestroy($image);
        
        echo 'Image uploaded and processed successfully.';
    } else {
        echo 'Failed to upload image.';
    }
}
?>
