How did you get that result? What is your configuration? I just ran the same exact code and got 0.1.

Apparently it’s been fixed since, but that’s still the version that comes with Hardy Heron.

That’s an old version, I’m surprised any updating version of linux would not update PHP as well.
On another note, I’m assuming from this post you don’t like PHP that much do you? Is it in a similar fashion to why you don’t like Apple/Mac stuff, because of the fanboys and the pretty sloppy coding and the many other problems that plague PHP’s community?

I dislike PHP because it’s too obviously designed by blithering incompetents who haven’t had a day of formal education in computer science or programming in their life. It’s a horrible language in ways that makes C++ look like an elegant masterwork. I would dislike it even if it had no users at all.
With Apple, on the other hand, I mostly just hate hipsters. Their products are shit in very real ways, but if I never had to use them I wouldn’t particularly care about that aspect.

Why do you want a list if you’re not going to know what it means?
Consider the existence of the following three functions symptomatic: array_map, array_walk, and iterator_apply.
If you don’t consider horrific standard libraries to be language problems per se, there’s, for example, the fact that PHP has exactly three scopes: global, function, and superglobal.
And then there’s this and this and a whole host of other bullshit.
Obviously any language that thinks Perl was a good enough idea to do it again (except without the convenient regex syntax, which is literally the only thing Perl has going for it) is going to be broken from the outset, but even taking that in account, PHP is exceptionally bad.
The only way anyone could think PHP was an okay language is if they’ve never used anything else in their life, and also haven’t used PHP itself a whole lot.
There’s really no two ways about it: PHP is a bad language, and anyone who disagrees is a moron.
You could spend years documenting all the pig ignorant design decisions that went into PHP, and that’s without even touching the quality of the interpreter.
The fact that it’s usually paired with the worst SQL “implementation” in the history of relational databases in the LAMP stack is just the icing on the cake.

Because it’s behind other languages…? Can you elaborate on what you said?

Are you seriously asking for a list of things that are wrong with PHP as a language?

I personally haven’t taken compsci, so I can’t just understand you saying ‘they don’t know what they’re doing.’ Without showing examples or proof and just saying ‘PHP is horrible’ it makes you seem elitist and is subjective.

At least you actually know your stuff and don’t just say ‘Oh hurr durr PHP sucks it’s not got good OOP and shit’ and actually backed up what you said.
