The Right Tool for the Job
Okay, just a couple of points.
First of all, all of the discussion concerning PHP vs Ruby is rediculous. I think that you are pretty limited in your ability if you only know one programming language - regardless of your skill level in that language. Every task - programming or otherwise - has a tool that is best suited to it's solution. Just as there are specific patterns that can help solve problems, your choice of platform/language/font size in your favourite editor are all variable. I wonder how many sites are using Bash Scripts as CGI programs? How many use PHP as their shell utility language? Have you ever tried to hammer in a nail with a screwdriver? Stop the "discussion" about PHP vs *, it's pointless. Learn as much as you can and make informed decisions.
Secondly, I think the main problem is that a lot more people are using PHP for Enterprise level applications and that is why there is more concern over it breaking now because of a mere point upgrade. Take a look at the growth of this community (the Advanced PHP forum) since it was first started back in January of 2002. PHP at the time was in version... 4.1 or something? I dunno about you all, but I thought 4.x was a Godsend after the 3.x series and was a real jump towards making it a serious language. Remember the "script" vs "real" language debates? The problem may be that the community using PHP has changed, grown up from simple scripts embedded in HTML. Even though Zend has taken over the engine, the core developers perhaps have not changed their practices and mindsets to reflect the newer, more Enterprise minded developers that are doing some amazing things with PHP.
Just my thoughts,
