Here's a list of every function beginning with the letter "A" in the PHP function index:
I remember my first experience with PHP way back in 2001. Despite my questionable pedigree in ASP and Visual Basic, browsing an alphabetical PHP function list was enough to scare me away for years. Somehow, perusing the above list, I don't think things have improved a whole lot since then.
I'm no language elitist, but language design is hard. There's a reason that some of the most famous computer scientists in the world are also language designers. And it's a crying shame none of them ever had the opportunity to work on PHP. From what I've seen of it, PHP isn't so much a language as a random collection of arbitrary stuff, a virtual explosion at the keyword and function factory. Bear in mind this is coming from a guy who was weaned on BASIC, a language that gets about as much respect as Rodney Dangerfield. So I am not unfamiliar with the genre.
Of course, this is old news. How old? Ancient. Internet Explorer 4 old. The internet is overrun with PHP sucks articles – I practically ran out of browser tabs opening them all. Tim Bray bravely bucked this trend and went with the title On PHP for his entry in the long-running series:
So here's my problem, based on my limited experience with PHP (deploying a couple of free apps to do this and that, and debugging a site for a non-technical friend here and there): all the PHP code I've seen in that experience has been messy, unmaintainable crap. Spaghetti SQL wrapped in spaghetti PHP wrapped in spaghetti HTML, replicated in slightly-varying form in dozens of places.
Tim's article is as good a place to start as any; he captured a flock of related links in the ensuing discussion. As you read, you'll find there's an obvious parallel between the amateurish state of PHP development and Visual Basic 6, a comparison that many developers have independently arrived at.
Every solution I've ever seen or developed in PHP feels clunky and bulky, there is no elegance or grace. Working with PHP is a bit like throwing a 10 pound concrete cube from a ten story building: You'll get where you're going fast, but it's not very elegant. ... I love PHP, and it's the right tool for some jobs. It's just an ugly, cumbersome tool that makes me cry and have nightmares. It's the new VB6 in a C dress.
From my own experience, and the countless of online tutorials and blogs, many PHP developers are guilty of the same crap code VB developers were once renowned for. OO, N-Tier, exception handling, domain modeling, refactoring and unit testing are all foreign concepts in the PHP world.
Understand that as a long time VB developer, I am completely sympathetic to the derision you'll suffer when programming in a wildly popular programming language that isn't considered "professional".
I've written both VB and PHP code, and in my opinion the comparison is grossly unfair to Visual Basic. Does PHP suck? Of course it sucks. Did you read any of the links in Tim's blog entry? It's a galactic supernova of incomprehensibly colossal, mind-bendingly awful suck. If you sit down to program in PHP and have even an ounce of programming talent in your entire body, there's no possible way to draw any other conclusion. It's inescapable.
But I'm also here to tell you that doesn't matter.
The TIOBE community index I linked above? It's written in PHP. Wikipedia, which is likely to be on the first page of anything you search for these days? Written in PHP. Digg, the social bookmarking service so wildly popular that a front page link can crush the beefiest of webservers? Written in PHP. WordPress, arguably the most popular blogging solution available at the moment? Written in PHP. YouTube, the most widely known video sharing site on the internet? Written in PHP. Facebook, the current billion-dollar zombie-poking social networking darling of venture capitalists everywhere? Written in PHP. (Update: While YouTube was originally written in PHP, it migrated to Python fairly early on, per Matt Cutts and Guido van Rossum.)
Notice a pattern here?
Some of the largest sites on the internet – sites you probably interact with on a daily basis – are written in PHP. If PHP sucks so profoundly, why is it powering so much of the internet?
The only conclusion I can draw is that building a compelling application is far more important than choice of language. While PHP wouldn't be my choice, and if pressed, I might argue that it should never be the choice for any rational human being sitting in front of a computer, I can't argue with the results.
You've probably heard that sufficiently incompetent coders can write FORTRAN in any language. It's true. But the converse is also true: sufficiently talented coders can write great applications in terrible languages, too. It's a painful lesson, but an important one.
Why fight it? I say learn to embrace it. Join with me, won't you, in celebrating the next fifty years of glorious PHP code driving the internet. Just don't forget to call the
maintain_my_will_to_live() PHP function every so often!
