MononcQc posted:Well, if it's anything that can be confusing to someone else looking over your code, I'd say it's not a good idea. In this case, it's 99% sure to spark some confusion, so I'd go against it just because of that. I disagree. One of the benefits of using classes is the ability to use simple, descriptive member names that won't collide with the same name in other contexts. If $obj->delete() is an appropriate name for what the function does, I'd use it. The fact that it's obviously an object member instead of a global function should eliminate any confusion.

I agree that sanitizing should be the last step before output or very close to it, but that doesn't necessarily have anything to do with string concatenation syntax. In most of my applications, the process that outputs data retrieves all of its input from a store that sanitizes everything it receives.

I'm more of a designer and Flash/Actionscript programmer, so I don't really have much knowledge about PHP other than obvious coding conventions. You're probably opening a file handler for writing instead of appending, e.g.: $f = fopen('file.txt', 'w'); The 'w' should be 'a' to append instead of overwrite. $f = fopen('file.txt', 'a'); http://www.php.net/fopen

Lankiveil posted:I'm looking at implementing my own RSS feed generator, which will work off of a series of existing tables in my database. I had planned to simply write a PHP script that output the required XML straight to the client, but most of the tutorials that I've seen on the web do it by generating a flat text file at a regular interval and having that serve as the feed. You should be fine. The most obvious reason off the top of my head is performance, but I wouldn't worry about it unless you anticipate enterprise-level traffic right off the bat.

Little Brittle posted:The problem is, the site redirects urlencoded requests and curl can't follow the redirect. If I pass an urldecoded string to curl, it automatically tries to grab the urlencoded page. Unless there is some little-known parameter that makes curl ignore urldecoded URLs, I don't see a solution to grab a page with spaces in the URI when the host site requires it. That doesn't make much sense. Like Zorilla said, it violates the standards. What happens when you put the URL with spaces in a browser's address bar? How about when you replace the spaces with + instead of %20? Edit: By the way, you can tell cURL to follow redirects by setting the CURLOPT_FOLLOWLOCATION option to true.

Little Brittle posted:It's the actual path where the content is located. Properly encoded URLs are redirected to the standard-violating path. That's what doesn't make sense to me. The browser should encode the URL before it gets sent. If the browser requests a URL with illegal characters, the server should respond with a bad request error. If it requests a URL with encoding, the server should unencode it before it tries to resolve it to a local file path, so you shouldn't need the redirect in the first place.

If you wanted to put foreach loops out of your templates, you'd probably have to generate all the HTML that requires looping in the controllers and then pass that off to the views ... the first and worst sin of home-grown template engines is usually that they suck at iteration, which usually means they suck loving period. either you're using a foreach() in your templates, or you have some equivalent to a foreach() method in your template engine, or your template engine loving sucks. even trivial web sites usually need some way to loop through a collection, for chrissake

If you're looking for the full path for the uploaded file on the remote machine, e.g. c:\My Documents\image.gif, that information doesn't get submitted. If you want the local path of the uploaded file on your server, check $_FILES['filename']['tmp_name'] instead.

I'm using a framework that handles database queries with prepared statements. Lately I've been struggling with huge dynamic queries that need to swap joins and other clauses based on various conditions. It's a major headache to do it by manipulating strings. I've looked at ORM frameworks like Propel, but they seem like more trouble than they're worth for this project. All I really need is a library that helps me generate dynamic SQL without forcing me to append strings and fight over misplaced clauses and commas. My current solution is a class that works something like this: php:<?
$select = new Select();
$select->table('customer');
$select->field('customer.name', 'customer.email');
$select->order('customer.name');
$select->where('customer.country = ?', 'US');
if ($user == $not_an_administrator) {
// Add a join and a where clause to filter for customers that belong to
// this user
$select->innerJoin('representative', 'representative.id = customer.repid');
$select->where('representative.id = ?', $userid);
}

fletcher posted:I've been a big fan of EditPlus for awhile now for all my PHP needs. I really find myself wanting an object outline and some basic auto-completion sometimes. Are there any lightweight editors that do that for PHP on windows? I like Eclipse for Java but didn't really like it for PHP. I'm in the middle of evaluating NuSphere PhpEd. It's not as lightweight as EditPlus, but I imagine that would be true of any IDE that can outline objects and complete code. It's nowhere near as heavyweight as Eclipse or Visual Studio, either. So far I'm really impressed. I downloaded a massive project (around 10MB of source code) for local development. Frankly, I expected PhpEd to get a little confused about the class hierarchy. I opened a script and instantiated a derived class that depends on an autoload function for inclusion. The editor gave me all of its public members without a hiccup. It includes doc comments in the code completion if they exist (method and argument descriptions, etc.). And this is on an antiquated Thinkpad running XP Pro with 512MB of RAM. Unfortunately, it's also not as cheap as EditPlus, but a free trial is available. DaTroof fucked around with this message at 00:56 on Jan 5, 2009 |

That sounds pretty confusing after reading it, so here's an example: You're trying to get the element's key, not its value.

$header = array("Home","Info"=>array("E-Mail","Other"));
$keys = array_keys($header);

Store the nonce (in your example, the action value is a nonce) in a MySQL table with a timestamp and delete records older than you want to allow. Delete the nonce when it's requested. Storing them in MySQL is the exact opposite of eating up all your RAM. Edit: Sorry, "exact opposite" is an exaggeration. My point was that an RDBMS is supposed to be a scalable datastore, and you might as well take advantage of it for as much as you can, which is a long-rear end way.

You can use, for example, mysqli with nothing but procedural functions, but it still uses objects in the background. I strongly recommend that you familiarize yourself with OO concepts unless you intend to never work on projects that are non-trivial or involve other people.
