Extension:StockQuote

This extension allows you to have (delayed) stock quotes on your site by using the tags (SYMBOL).

Although it will perform a number of other functions as well, which you can perform by appending what you want after the part of the tag (such as GOOG ).

Code
Add this line to LocalSettings.php.;

require_once('extensions/StockQuote.php');

The following code should be added to the extensions folder as StockQuote.php

 'StockQuote', 'url' => 'http://www.mediawiki.org/wiki/Extension:StockQuote', 'author' => 'Olipro' ); function wfStockQuote { global $wgParser; $wgParser->setHook('stock', 'StockQuote'); }

function StockQuote($input, $argv, $parser) { global $wgParser; $wgParser->disableCache; //ATTENTION; DISABLE THIS LINE IF YOU ARE ON HIGH LOAD! $info = file_get_contents("http://finance.yahoo.com/d/quotes.csv?s=$input&f=sl1d1t1c1ohgv&e=csv"); $info = str_ireplace('"', '', $info);	$info = explode(',', $info);	if($info[1] == '0.00') { return 'ERROR'; }	if($argv['quote']) {		return $info[1];	} elseif($argv['change']) {		return $info[4];	} elseif($argv['high']) {		return $info[6];	} elseif($argv['low']) {		return $info[7];	} elseif($argv['open']) {		return $info[5];	} elseif($argv['volume']) {		return number_format($info[8]);	} else {		return $info[1];	} } ?>
