How can PHP be utilized to create a user-friendly interface for members to upload and display images on a website, while ensuring data integrity and security measures are in place?

To create a user-friendly interface for members to upload and display images on a website while ensuring data integrity and security measures, we can use PHP to handle the image upload process, validate the file type and size, store the image securely on the server, and display the images on the website using appropriate HTML markup. 

<?php
if($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_FILES['image'])){
    $errors= array();
    $file_name = $_FILES['image']['name'];
    $file_size = $_FILES['image']['size'];
    $file_tmp = $_FILES['image']['tmp_name'];
    $file_type = $_FILES['image']['type'];
    $file_ext=strtolower(end(explode('.',$_FILES['image']['name']));
    
    $extensions= array("jpeg","jpg","png");
    
    if(in_array($file_ext,$extensions)=== false){
        $errors[]="extension not allowed, please choose a JPEG or PNG file.";
    }
    
    if($file_size > 2097152){
        $errors[]='File size must be less than 2 MB';
    }
    
    if(empty($errors)==true){
        move_uploaded_file($file_tmp,"images/".$file_name);
        echo "Success";
    }else{
        print_r($errors);
    }
}
?>
