Open Source PHP for Inventory Management

[hoopplaya4]

Hi All,

 

Does anyone know of any online applications (preferably PHP and open source) that will help with inventory management of technical equipment?  I am looking for something with the following:

 

1) Track current inventory of equipment that can be rented out to end users.

2) Front end where users can make requests to rent/check-out equipment for an extended period of time, e.g.-- a user can reserve a camcorder for June 15, from 10am - 12pm.

 

Thanks!
