Learning PHP is easy anyone can do it over a few hours on a Sunday afternoon. That was one of the primary goal of creating PHP and has been very successfully achieved. Today everyone and their cousin twice removed can write PHP. Combine that with sites like sourceforge and freshmeat and you have got phenomenal amount of code which is very poorly written.
Now set these coders in a poor job scenario and you have a crowded fish market with PHP projects being bid at less than $1 an hour without any understanding of what they are in for!
Contrary to what most readers will expect the client is the last person to understand the difference. Another disturbing factor which came to light was a popular notion among neo DotCommers that if you get your technology cheap your success is assured!
However as expected this situation could not last forever, the dynamics of market forces had to take over. Cracks are showing up in software designed 6 month ago as the site becomes popular. Increasing numbers of projects are never being delivered and then there is a category of programmers and clients who are sensible and re-outsourcing to more experienced PHP programmers before too late.
My condolences to the gurus who could not survive this shake out, planning your cash flow would have helped. As for the stupid a** h**** who perished – good riddance
