Agrikk posted:...  The thing with PHP is that there is no such thing as "an array of fixed size", but let's say you are artificially setting a fixed size to an array - say of size 10. This means your key are 0, 1, 2, ..., 9. You can represent the set of keys with the following array: $keys = array(0, 1, 2, 3, 4, 5, 6, 7, 8, 9); Of course, you can generate this array using array_keys or range. Next you have your list of you want to insert into your array, let's call it $items. As long as you can make the assumption that the size of $items is always equal to or smaller than the array you are inserting into, you can do something like this: php:<?
shuffle($keys);
foreach($items as $item)
{
$array[current($keys)] = $item;
next($keys);
}
?>

Once it found an empty slot, it would break out of the loop. This code snippit was going to be a function that would be called many times for placing stars, gas giants, belts and worlds, and I figured that many rerolls might be necessary in more crowded systems, which is okay with me.

I'm not sure if this belongs here but does anyone have any recommended reading on APIs? It seems like it's common knowledge yet I have no idea on how to use them (for example, something like logging in thru digg using their API). I'm pretty familiar with PHP but everytime I read something on how to use X API, it goes over my head.

It seems like it's common knowledge yet I have no idea on how to use them (for example, something like logging in thru digg using their API). API translates to "the way to interface with our poo poo." Most websites (Digg) have a web services API. You make requests to their site using certain URLs and certain query string or POST parameters, and you get data back, usually in JSON, sometimes in XML, or whatever they want. There are a handful of web service API types. The most modern and trendy is "REST", which is another way of saying "use the HTTP verbs (GET, POST, PUT, DELETE, etc) to access resources." For example, sending "DELETE /post/1234" would delete that object. Often, REST-ful web services return data in JSON. There are other, older ways to do web services. SOAP is one of the more convoluted and evil ways. It's a pain in the rear end wrapped in XML, and should be avoided if you don't want to lose your mind. Sometimes the API is only exposed through code. They'll give you a set of files that usually contain a class or fifteen, and then the documentation on using the classes to do their thing. You'll usually find these monstrosities are in Java, and even though they use SOAP or something similar, they'll force you to use their code instead of giving you the API documentation because they are fucktarded. This unfortunate method has also been seen in .Net land, and is often used by "Enterprise" systems, because they take themselves too seriously and don't know how to version a web service / their toolset prevents them from implementing a versionable web service. Does this help in the least? McGlockenshire fucked around with this message at 04:12 on Jul 26, 2009 |

Most interestingly and/or horrifyingly, it's possible to get zero, null, and -1 error states depending on how bad the input is.

I'm frustrated man. Alright, so I'm the owner of a site called Happyfood, and have decided to update it from it's archaic pure html structure. I decided to use PixelPost (http://pixelpost.org). They have a shitload of templates, and I've been really busy completely customizing AliPixel (http://www.pixelpost.org/extend/templates/alipixel/). Here's my site for reference: http://wherefoodishappy.com/index.php There are two things that I need help with. First off, I have written several comments, and they down show on the drop down menu. They DO show on the site (like where it says "Comments: 2). AliPixel's comments and javascript is based of http://treeswing.net/, as well as http://theworldin35mm.org/ if that helps at all. The second problem I have is that I'm trying to center that header on the top, while keeping all of the buttons under it like that. If needed I can send you the .html file, or if really necessary, the entire customized theme as a .zip. Please help me out!

A couple of best practices questions: 1) I have some functions (like "get a list of countries from the database") that are used on multiple parts of the site. Rather than split them out into a file and include that file, I've put them into a class which, combined with an autoload in my standard header include, means I don't have to worry about including anything. I just do InternalFunctions::getCountries() and it's done, since it's in InternalFunctions.php. Is this a good thing, or should these things not be in a class? 1a) I've also started including some HTML blocks in that thing, rather than use include files. i.e. InternalFunctions::displayTableStart to echo (without any PHP variable processing or anything) the particular start code for a table start that uses our classes and javascript. Should that simply be replaced with an include, and keep the table code all alone in an include file? 2) I've read that objects shouldn't try to do too much, that they should only really do one thing each. ("one reason to change", I've seen it put) But where is the line? I have a user data object that handles reading and writing to the database (via a mysqli object), sanitizing of the object data, generation of internal ID, etc. I can't really imagine how I'd split some of these things out.

If you want you can use __toString to do this:php:<?
class Password
{
public function __toString()
{
return "54321";
}
}
$pwd = new Password;
echo $pwd
?>

That would work but I'd highly question the need of creating an object if all you really want is a string (unless you're leaving out the other stuff done with a PasswordGenerator for clarity).

So this is what happens after my projects are feature complete but before they get tested, I go hog wild on experimenting with code and new features. My current expedition into the code mines: Singletons. Specifically, a mysqli singleton. Is this a good idea, and is it worth it? Right now, I have subclasses for all of the different databases we connect to, all of which are children of a central child class of mysqli. So I can just pass "new DatabaseConnection" to functions and it works. Using a singleton sadly adds another line (since you can't pass "DatabaseConnection::getInstance()" to a function expecting an object of DatabaseConnection) but it might be useful if it actually helps. I've been googling around and find many mixed opinions on singletons, but generally that they can be useful for database connections. However, we don't have *heavy* database work; maybe on the scale of dozens of queries a minute, rather than hundreds a second. So far as I can tell, we haven't had any performance issues so far, but then again, the production site is still using mostly code based on mysql, not mysqli, so I don't know if my conversion work will cause problems. Edit: Factory pattern. That's what I need. Not a singleton. Factory is working quite fine. Golbez fucked around with this message at 16:38 on Aug 4, 2009 |

Not sure if that's how I should be handling errors though. Is it an exception you want to show the user? Or do you want them to see a generic "there is a problem with this page" type of thing? I use set_exception_handler and don't have a single try/catch in my whole app. The exception handler function logs the exception so I can take a look at it later (as well as information used to help recreate it). Using the get_class function I look at the type of exception to determine what I display to the user. If it's a PublicException, I dislay the error message to the user. If it's anything else (PDOException, etc) I just display a generic error message or error page, depending on if it was a GET or POST that caused the exception.

I'm having a friendly arguement with a co-worker but neither of us can find compelling evidence. He says PHP was capable of prepared statements as early as PHP 4, while I say it was PHP 5. We're both shooting at MySQL here because PHP 4 automatically compiled with it, but he found something that looks like there was a DB2 library IBM put out. Can anyone settle this for us?

http://us3.php.net/manual/en/function.db2-prepare.php PHP 5 came out on 2004-07-13, ibm-db2's first beta release was 2005-05-06. However, ibm-db2 works with PHP 4 (and 3, for that matter). Whether or not this counts is fairly irrelevant though, as ODBC is not an extension and has supported prepared statements since PHP 4. Ibase, ifx, dbplus, and ovrimos also all had prepared statements in PHP 4.
