I should have asked about =& specifically since I saw it here. I still can't quite figure out what it's supposed to do differently than = does.

It makes a reference (which you can read about a few posts up..well the link in a few posts up).

Objects by default are referenced just using =, but when a =& is done, they perform a clone (a shallow copy essentially...sometimes called a hard link).

Think of it this way.

$a = 1;
$b =& $a;

$b++;

// $a will be 2 here.
var_dump($a);

if you did $b = $a, $a would still be 1. Instead of holding a value, it basically just links to another variable...a reference. It gets a bit more complicated when you start using references inside objects and passing in to functions, but it's pretty easy.

$a = 3;
$b =& $a; //$b is a reference of $a;
$b++; //changing $b DOES change $a

What type of situation would it be useful to use the =&? I understand what it does, I just don't understand why you would want that.

If you wanted a function that could return two values, you couldn't in php, because each function can only return one value to its caller. The way to get around this would be to send in a pointer to the function as a parameter and allow changes to be done on that. I use pointer here as something that is assigned using the =&.

Ohhhhh that makes sense. Whenever I needed to do that I just returned an array with everything I need in it.

It also helps when you don't want your data being copied all over the place. Say you're operating on a huge array, and instead of passing it in to a function, you could reference it in. It also comes in very handy when you're using recursive functions.

Also consider if its simpler / clearer to test for the cases where you shouldn't be setting curr_sector to -1, and test for that negated:

php:

<?
if(!(SIMPLER_CLAUSE))
{
  $curr_sector = -1;

Lastly, if you're using -1 as an 'not valid' value in a variable that normally stores numbers, get into the habit of using FALSE for that - then test for it explicitly:

php:

<?
$val = myfunc();
if($val !== FALSE && YOUR_OTHER_TESTS_ARE_PASSED)
{
  // use $val knowing its valid
}
?>

So; working on the assumption that this is a test for the current sector being valid to use and then setting it to a value that (maybe) causes a loop to terminate... (also took a stab at what might be most likely to be the "normal" fail condition)

php:

<?

using mysql 4.1

I've sent data to the page via a form POST, and converted the POST results into variables

I'm trying to run an UPDATE query with the data from the form using the following

$sql = "UPDATE `projects` SET 'ProjName' = $name WHERE `Key` = $key123";
$result = mysql_query($sql)
or die("Couldn't execute result query."); <---this is where I die

I've verified that my variables are correct by running an echo on just them. Any ideas?

Shouldn't you be escaping your php variables from the sql string?

$sql = "UPDATE `projects` SET 'ProjName' = {$name} WHERE `Key` = {$key123}";

or alternatively

$sql = "UPDATE `projects` SET 'ProjName' = ".$name." WHERE `Key` = ".$key123;

If it's inside double quotes, "simple" variables will be replaced. Complex ones (array values, object properties) would need to be escaped, but not here.

Use PDO so you can just write nice clean SQL statements, and you never have to worry about escaping a variable again. (this needs to be in the OP, this comes up time and time again)

Khorne: May 1, 2002

Are there any extremely light-weight CMS systems that are easy to modify to fit in to an existing framework?

Things I am looking for:

Very simple user table (accountId, Username, Password, Email, Access) so it can just use the existing one
News posts/static pages (updates / information pages)
Article types with varying access requirements and an easy way for admins to revert edits (wiki-like system for documentation)
Loads a php file and passes it an array or object with page information (no smarty, no intricate templating systems)

All requirements don't have to be met. I know I am going to have to modify whatever I do choose to use. I cringe at the sight of most CMS systems I've checked out. TikiWiki and MediaWiki are bloated and geared more toward lame wiki sites than practical applications. Most of the smaller CMS projects seem poorly implemented or downright bad.

I'm fairly close to coding it myself, but it's a bad idea for me to take on another project. I have far too many left unfinished and an ever decreasing amount of free time.

Roctor: Aug 23, 2005; The doctor of rock.

So I'm working with a guy to make a site for the use of people in the musician's lounge subforum. The guy I'm working with got a SA authentication script from the gbsfm guys. At first glance it looks pretty solid, but I can't get it to correctly set the cookies necessary so that the script can check a user's profile for the auth key.

So here's the relevant portion of the script (I hope this isn't crossing any lines with the gbsfm crew):

php:

<?
# The user we want to check, and they key to check
$user = stripslashes('roctor');
$key = '36188438ac1d50cfb5eb7ae34882b988';

# SA parameters. Use your SA user ID and the md5 hash of your password
# This is the user ID of my gimmick account,
$sauserid = '83280';
$sapasswordhash = '(my password hash)';

# Setup values to use in the CURL operation
$url = "http://forums.somethingawful.com/member.php?s=&action=getinfo&username=".urlencode(stripslashes($user));
$cookie = "bbuserid=$sauserid;bbpassword=$sapasswordhash";

# These aren't necessary, but it helps to prevent setting off any alarms
$useragent = 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0';
$referer = 'http://forums.somethingawful.com/usercp.php?s=';

# Initialize CURL and start collecting the output buffer
$ch = curl_init();
ob_start();

# Setup CURL options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_COOKIE, $cookie);
curl_setopt($ch, CURLOPT_USERAGENT, $useragent);
curl_setopt($ch, CURLOPT_REFERER, $referer);

# Execute and close CURL
curl_exec($ch);

# Get the returned HTTP text and release the output buffer
$response = ob_get_contents();
ob_end_clean();
?>

So the curl works correctly and the page is stored in the $response variable, however, the page that is stored is a "you must be logged in" page, rather than the user profile. I kind of suspect the password has I'm using, but I got the value for the password hash directly from the cookie that SA sets with the 'view cookie' firefox addon.

I'm kind of at a loss about how to get the verification working correctly since there's not really a whole lot of easy to find documentation out there. Anybody know what I'm doing wrong here? Could it be some sort of server configuration?

If it's any help, the script is currently up at https://www.musicianslounge.org/test

Here's an example of another site that uses this. You must have an Alluvion account, which only requires that you put something in your SA profile to verify. No entering of your SA password anywhere.

So yeah, two separate accounts.

Nah, I haven't really used CI. I read up on a few frameworks and decided on Kohana cause it was strictly written for PHP5, which is fine since that's what we're running on our server (and it seemed like the easiest to get my project off the ground with.) For the most part, Kohana is really easy to work with, and while the documentation isn't as stellar as I'd like it to be it does the job (as does their forum.) What I like about it so far, and I'm not sure if CI has this functionality too, is that I can override core functionality easily with my own libraries. I have my own default controller class that handles session stuff and authorization with users in a vBulletin database in the CMS I talked about.

The big problem with it right now is that it's still in a wild state of development -- they changed a bunch of the core functionality between 2.1 and 2.2, and nothing really feels concrete in it still since there seems to be even more core changes in the 2.3 svn version. My site uses some on-the-fly routing with the _default() class function, which is one of those major changes they made in 2.2. That's partially why I've stuck with 2.1 so far (the other reasons being I've been busy with my other, real job and extreme laziness/procrastination in my spare time.) Plus, if it ain't broke...

I don't think you have to worry about it being abandoned, but if you did want to switch over I'd follow their update trac/changelogs for awhile to make sure they aren't drastically changing how core functionality works.

What I actually meant was its stability. I may just wait a while before using it as my primary framework for PHP. CI does have the ability to overwrite almost all functionality such as controllers/helpers/libraries although it seems like Kohana have a lot more versatility using an events system.

I'm not sure why imagepng would function that way. As a short-term hack for a library of hacks, you could use output buffering around the function and just dump the contents.

php:

ob_start();
imagepng($thumb, "blocks/".$numOfFiles.".png");

Storage, especially if/when you get to the point where you're using shark/netapp/isilon/whatever, is going to plotz if it has to stat() across a directory of 10000+ files. Try to keep it around 1-2k, you're golden, and really, it can scale forever.

(Ex: 3823423482340238423.png translates to 003/823/423/482/340/238/423.png), and you're looking at, max, around 2k entries per directory, which about any OS or storage system should be able to handle

File size versus FS sector size being left as a discussion for later, as is the extended cost of walking up that whole directory tree.

Thanks. Yes, it will eventually go to different directories. I never thought of the way you suggested, so thank you.

edit:

Isn't that scaling way further into the trillions of possible files?

Acer Pilot: Feb 17, 2007; put the 'the' in therapist

With an array like this:

php:

<?
Array
(
    [0] => Array
        (
            [0] => -3
            [1] => -2
            [2] => -1
            [3] => 0
            [4] => -1
        )

    [1] => Array
        (
            [0] => -3
            [1] => -2
            [2] => -1
            [3] => 0
            [4] => -1
        )

    [2] => Array
        (
            [0] => -1
            [1] => -1
            [2] => 1
            [3] => 2
            [4] => 3
        )

    [3] => Array
        (
            [0] => -1
            [1] => -1
            [2] => 26
            [3] => 27
            [4] => 28
        )

    [4] => Array
        (
            [0] => -1
            [1] => -1
            [2] => 51
            [3] => 52
            [4] => 53
        )

)?>

Would it be very memory/cpu intesive if I looped through this and checked for conditions?
