PHP Bid is written in clean, modern PHP 8 with MySQL and no heavy framework. You get every file in readable, unencrypted source code, and you host it on any standard web hosting or server.
With a hosted platform, your marketplace exists only as long as you keep paying. With PHP Bid the code, the data and the customers are yours, on your own server.
Readable code means any PHP developer can customize your site: new payment gateways, new auction formats, integrations with your other systems.
Security is built in: prepared statements against SQL injection, CSRF tokens on every form, escaped output, hardened session cookies and secure password hashing.
