First, log in to your hosting control panel and obtain the hosting address. Then create an FTP account in the file management section and record the account and password.
Compress all PHP files and related resources (such as images and configuration files) into a ZIP or TAR file for easier upload and management.
Use an FTP client (such as FileZilla) to connect to your hosting, and upload the packaged source code to the designated directory.
Make sure PHP files have permissions set to 644 or 755, and directories set to 755 or 775, to ensure the application runs correctly.
If your PHP application requires a database, create one in your hosting control panel and record the database name, username, and password.
Edit configuration files (such as config.php) according to your application's needs, filling in database connection information or other necessary parameters.
Enter the hosting address in a web browser to access your uploaded PHP application. If the page displays correctly, the source code has been deployed successfully.
