the secret of PHP
Posted by Stas on May 21, 2008
So, another “PHP sucks” post, this time from Jeff Atwood. He actually ends up even kind of praising PHP, surprised by its success. I have a couple of thoughts on that topic too.
First, people really need to stop reading something on PHP written somewhere in 2005 (probably about experiences that happened in 2001) and apply it to PHP as it is now, without even checking around for current trends. It’s as if people would dig up books from middle ages saying that there are only seven metals in existence or debating about phlogiston, and would use it speaking about the modern chemistry. Come on!
Then the next thing apparently wrong with PHP is too many functions. Right. Since when? Since when having a lot of functions is a problem? Does it hurt anybody? Does it make writing PHP code harder? Does it make programmer less successful in achieving his goals?
About keywords I could kind of understand – OK, a lot to remember (though I didn’t see anybody really having trouble to remember such complicated keywords as “while”, “if”, “class” or “public”) and it takes out some good English words that could be used as function/method names to confuse the enemy (who wouldn’t want to have function named endforeach() or static(), not to mention function()? too bad those are not available!). But complaining there’s too many actual functions that allow you to do real useful stuff? That is the thing that is bothering people? That is what scares people away from using the language “for years”?
The next beef with PHP is that people write sucky code on it. No, really, they do? Must be something really wrong with this language. It’s not like people write mind-bogglingly sucky code on every other “good” language on the planet. But I get it. The intent was – PHP makes easy to write sucky code. Yes, this is true. As true as “Porsche 997 makes it easy to drive at 100mph into a brick wall”. PHP makes it easy to write various kinds of code – and if 90% of code written is sucky, then 90% of PHP code would be sucky. But my experience says quality of the production code almost never has much to do with the language, but only with the culture – organizational and personal, and with choosing right ways to do the job. The rest is just bad statistics in play. Like “I know 7-year-old writing websites, and his PHP code sucks”. I bet his Haskell code rules though ;)
That’s not to say PHP couldn’t use improvement. It could. And it does, actually – and there’s enough room for improvement still, in many areas. But it probably would never satisfy purists. It’s practical. Maybe it doesn’t allow you to write whole programs in one line of uncomprehensible character soup or play with high-level math theory concepts, but it allows people to write web applications. So they do – so where’s the surprise when one morning somebody wakes up and discovers there’s a ton of web applications around and they are written in PHP? :)
P.S. I wish for every 50 “PHP sucks” blogs people would write one good RFC.
