How to use PHP to implement online photo album and picture management functions

The photo album function is very common in modern social networks and personal websites. Through online photo albums, users can easily upload, manage and share their photos. This article will teach you how to use PHP to implement a simple online photo album and picture management function.

1. Create database and table
First, we need to create a database and create a table in it to store photo-related information. You can use the following SQL statement to create a table named "photos":

CREATE TABLE `photos` ( `id` int(11) NOT NULL AUTO_INCREMENT, `title` varchar(255) NOT NULL, `description` text NOT NULL, `filename` varchar(255) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2. Create a file upload form
Next, we need to create an HTML form to allow users to upload photos. In the form, we add a file input field and other related fields such as title and description. The following is a sample code:

 标题：  
 描述：  
 照片：  
  

3. Write upload file processing code
In the PHP script for uploading photos, we need to process the files uploaded by the user and save them to the server. The following is a sample code to implement the upload file processing function:

prepare('INSERT INTO photos (title, description, filename) VALUES (?, ?, ?)'); $stmt->bind_param('sss', $title, $description, $filename); $stmt->execute(); echo '文件上传成功！'; } else { echo '文件上传失败！'; } } ?>

4. Display the photos in the album
Finally, we need to write a PHP script to display the photos in the album. The following is a simple code example:

query('SELECT * FROM photos'); while ($row = $result->fetch_assoc()) { echo ''; echo '
' . $row['title'] . '
'; echo '
' . $row['description'] . '
'; } ?>

With the above code, we can create a simple online photo album and picture management function. Users can upload photos and the system saves them to the server and stores related information in a database. At the same time, users can also browse photos in the album.

It should be noted that in order to ensure security, we should perform some verification on files uploaded by users, such as checking file type, size, image size, etc.
