Guilt by association: We Run The Game is running on some gallery software I wrote. The goal (and I guess there’s a pattern forming here) was extreme simplicity and speed.

Formatting date & time for RSS 0

find more posts in: php, rss

According to the RSS spec, all of the dates in your RSS content should be in RFC 822 format. That means they should look like this:

Sat, 07 Sep 2002 09:42:31 GMT

Here’s a PHP function that will take a timestamp and give you that string:

function rss_time($time){
	return strftime("%a, %d %b %Y %H:%M:%S %z", $time);
}

I’m not proud of this 1

…but I didn’t have much of a choice:

function parse_date_from_string($string=""){
	$month_names = array("", "January","February","March","April","May","June","July","August","September","October","November","December");
	$regex = "/(\d{1,2})[-|\/|\.](\d{1,2})[-|\/|\.](\d{2}|\d{4})/";
	$date = array();
	if(preg_match($regex, $string, $matches)){
		$month = preg_replace("/^0/", "", $matches[1]);
		$date['month'] = $month_names[$month];
		$date['day'] = $matches[2];
		if(strlen($matches[3]) == 2) $matches[3] = "20" . $matches[3];
		$date['year'] = $matches[3];
		$date['string'] = trim(preg_replace($regex, "", $string));
	}
	return $date;
}

Super simple PHP gallery 3

Just save this as index.php and put it in a directory with a bunch of images. Images are displayed one per page (newest images first), and clicking on an image takes you to the next one.

<?
exec("ls -r|egrep -i \"\.(gif|jpg|jpeg|png)$\"", $files);
$files = array_reverse($files);
$request = $_SERVER["QUERY_STRING"];
if(!(is_numeric($request) && $request > 0 && $files[$request - 1])){
	$request = count($files);
}
$r_index = $request - 1;
$next = $r_index;
if($next==0 || !$files[$next-1]){
	$next = count($files);
}
?>
<html>
<head>
	<meta http-equiv="Content-type" content="text/html; charset=utf-8">
	<title>my image gallery</title>
 
	<style type="text/css" media="screen">
		a img{ border:0; }
	</style>
 
</head>
<body>
	<table border="0" cellspacing="0" cellpadding="0" width="100%" height="100%">
		<tr><td align="center" valign="middle"><a href="?<?=$next?>"><img src="<?=$files[$r_index]?>" /></a></td></tr>
	</table>

Bookflipper 0

find more posts in: internet, php

Bookflipper is a tiny web app that serves up pricing information for used books from the Amazon API. My friend Brian has been picking up cheap books and selling them on Amazon for a profit. Now when he’s wondering if a purchase is going to pay off, he can just pull out his cell phone and enter the book’s ISBN into Bookflipper to see what the market is like.

Example 1
Example 2
Example 3

The page size is usually between 0.5-0.6k, thanks in part to some output buffer trickery. Of course, the preview image is much bigger but it seemed too useful to get rid of.

My name is Joey Nelson. I'm a web developer living in Portland, OR. I'm married to an awesome lady and we have two weird little pugs. I do a weekly comedy podcast and make dumb songs with this guy Ben. I don't post to this blog very often, and very few people actually read it.
