No serious PHP developer actually go to php.net to read the documentation, literally all of the big PHP editors/IDEs come with an embedded manual so when you write strpos( it automatically tells you the order of variables.
If I really had to go to php.net to look up order of variables or even a function name then I wouldn't be programming in PHP at all, would take too long. Thankfully, since I'm not restricted to notepad I don't have to worry about this aspect.
Yeah, this is me too. I haven't done much PHP in the past year, but when I did, PHP.net was ALWAYS open in a tab or two. There was NO WAY you were gonna get me to use some bloated nasty Java based editor just to have code completion. Honestly though, Stackoverflow is my goto point if I want the better parts of php documentation comments. An answer with 7 or more votes is worth taking a look at.
