PHP At 20: From Pet Project To Powerhouse 281

snydeq writes: Ben Ramsey provides a look at the rise of PHP, the one-time 'silly little project' that has transformed into a Web powerhouse, thanks to flexibility, pragmatism, and a vibrant community of Web devs. "Those early days speak volumes about PHP's impact on Web development. Back then, our options were limited when it came to server-side processing for Web apps. PHP stepped in to fill our need for a tool that would enable us to do dynamic things on the Web. That practical flexibility captured our imaginations, and PHP has since grown up with the Web. Now powering more than 80 percent of the Web, PHP has matured into a scripting language that is especially suited to solve the Web problem. Its unique pedigree tells a story of pragmatism over theory and problem solving over purity."

    The great thing about PHP is that it's the one language that native, Java, .NET, python and ruby guys can all make fun of together.

      I'm a Java dev of nearly twenty years, and I used to make fun of PHP. That was until my company added a team of PHP developers to work on prototypes. Over the past eight years, they have constantly exceeded the productivity of my Java devs by more than tenfold. Yes, the PHP code is harder to maintain long term, but it's amazing how fast you can build things that work. It is the best glue language I've ever seen. Basically it's just a thin shim between C libraries, and no one can argue with the quality and expansiveness of the C libraries available for Linux. PHP lets us use them very, very quickly in web, command line, and GUI apps. The only real weakness I've seen is that PHP-GTK is not very well maintained.

        exceeded the productivity of my Java devs by more than tenfold

        On my team of twenty-one devs, we have eleven Java guys and three PHP guys. We do fortnightly sprint planning meetings and score backend tasks as a group. The Java guys do about 50 points per sprint of work. They're very consistent and dependable, which is nice from a management point of view. For the PHP tasks, we schedule 75 points per week. The PHP guys, over the past three years we've been doing this, are doing 5.5 times as much per developer. PHP is amazing.

        The problem is that on a per-Sprint basis, the PHP guys are very inconsistent. Sometimes they'll do two to three times as many points as we planned on, and in a few sprints, they got no points. So even though they're five times more productive on average, our management wants to move everything to Java because it is easier to manage. Also, since we recently released v1, we know PHP maintenance tasks are going to be even more inconsistent wrt time to fix.

          Points cannot be compared between teams, you know. That's like agile 101. Even if you try to standardize the scale through teams, you cannot prove that these points are the same thing.
          If you start measuring productivity with points, your developpers are going to game the system and change their scale to achieve your said productivy. Sometimes, it happens unconsciously.
          If you say "it's too expensive" then, they are going to game the system to reduce points. In either case, you lose.

        thin shim between C libraries
        That is a great point. Since the Microsoft fanbois hate Linux, they hate PHP. PHP is basically a way to call C libraries. That is why the library naming conventions in PHP are so inconsistent. It's because PHP is exposing those libraries, with all of their individual quirks, to an easy to use scripting language.

        Where I work, we converted a C-based CGI program that was developed from 1994 until 2009. At peak, I think we had nine C developers working on it. It took us only six months with three PHP developers to write a good PHP replacement that called our C libraries. Now I have two new college grads that are very productive adding features to the web site whereas before, I had expensive C programmers each with more than ten years of experience that took dozens of times longer to complete tasks. PHP has cut our development overhead by probably 80%. Now the three remaining C programmers can work on interesting projects rather than on web pages. PHP has, and this is not an exaggeration, saved my company.

      PHP is a truly terrible language, with a truly terrible API. Just look at functions like implode [php.net], which can accept parameters in either order. Also (according to one commenter), imploding an array of booleans results in the "true" values being converted to 1, and the "false" values being converted to empty string. That's just a single function. Don't even get me started on mysql_escape_string [php.net] vs. mysql_real_escape_string [php.net]

      The only reason it's so popular is that for such a long time it was the only choice for server side languages on a shared hosting environment. Even now there aren't really any good alternatives. Shared hosts still don't allow things like Java,.Net, or Node.JS on the server side unless you are prepared to pay a premium. Many hosts don't even offer Ruby, or Python, even though they don't require a constantly running process.

      PHP started off as a toy project, and although a lot of work has been done to add functionality to make it useful, it still shows that it was lacking a lot of design considerations. Object Oriented capabilities and namespaces were tacked on later, and it really does feel tacked on, because only a very small part of the available libraries use object oriented features.

      • Same way you do for just about any other language - don't trust any input given. Check it for type, check it for how it was delivered (POST vs GET vs reading from file/stdin/whatever), check it for a (sane) value, deal with unexpected or missing values in a sane way, etc. When using SQL stuff use PDO or mysqli class/functions to use prepared statements.

PHP does nothing to help programmers write sane, maintainable code. It's almost impossible to develop without having a browser tab open to php.net ("The online docs are great!" "Well, they'd have to be."). There is zero consistency with things like argument order. Dangerous legacy concepts like "mysql_real_escape_string" are only recently deprecated and don't have a set removal schedule.

    I used the original, or close to it.

    In 1995, I worked for a company in San Diego (MediaShare) that did Tesco's first online store.

    MediaShare had a publishing tool called ProductBase, that put product details in a database, and you could publish to print or CD-ROM (remember those?). I proposed to my boss that we could also easily publish to HTML, and he let me explore it.

    This turned ProductBase into basically a static-site generator, and Mediashare built some sites for some of their existing clients ("the threes" - 3COM and 3M - we put the 3M Adhesives catalog and 3Com's catalog of network products online for the first time) and some new ones.

    One of the new ones was Tesco, and I built a little shopping cart with a very-close-to-1.0 PHP script running under Netscape Server CGI.

    I would have never thought that PHP would still be kicking around this many years later. That was the last time I ever used PHP.
