David Lantz: "Thank you, this is by far the simplest, and most friendly utility for building db record system I have ever used. I wish I could get my systems guys at the office to purchase this for our company would be so very helpful and speed up a lot of work. I for one have used it for everything from a simple inventory record of my house, to a members record for my church just little pet projects and a test bed to test my own db builds and theories before having to hand code at the office..... it is a lot of fun to work with".
Grey: "We're a two-person company, it's just me an my wife. I'm the technical guru, and she handles the business operations. I have to know a lot about MySQL, but that's much too technical for her. I have frequently had to setup CGI scripts (I code in Perl) so she can manage some of our tables (suppliers, manufacturers, etc).

I discovered PHP Generator a couple of days ago, tried the free version,and within a few hours I had purchased the Pro version (as well as SQL Maestro for MySQL).

Today I am completing the conversion of the last of my custom table managers to PHP Generator. This is eliminating several thousand lines of code that I don't have to support any more!

Thanks for this fantastic product".
