Ok gotta react, since I'm a fan of PHP
1: PHP is a disaster when it comes to security. (following @comex and @i0n1c on twitter had made me hate it)
The big problem with PHP and security is that many people, by virtue of it being easy, with no clue of security, throw together some half-understood scripts and call it a day (or a website, actually). Since PHP is widely used this means many leaky PHP sites exist. On the other hand, if you know what you are doing, PHP is just as safe as any other language.
Gonna follow those two Twitters, who'll know.
2: No one seems to like.
3: from what I can tell the only reason it's the dominate language used on the web is because it's the main language used on the web.
4: I don't want learn it.
Yeah, not real problems right
? I think many people like PHP (although that's no reason to use it), but that's like always just a matter of taste. It is one of the most-used languages, doesn't that make it dominate by def? In any case it ensures lots of tutorials to exist, sadly most of which are bad. Maybe it's best just to choose something you're already familiar with and for which you can find enough resources to learn it properly.
