One of the things that has kept me with PHP, out of all the other languages I have to deal with, is its simplicity and an almost obsessive adherence to not breaking existing code. I know I have said it many, many times, but I think these are two of the main drivers behind why PHP has continued to dominate the web. In a way, the “if it’s not broken, don’t fix it” mentality has led to many software programs continuing to run and be updated as needed. by Chris Tankersley
