There are many reasons why you might not want to have Chef Server in your deployment path. Or, as this example shows, you don’t want to host your own Chef Server. We instead use Hosted Chef, but purely as a…

I’m a big user of Chef, but was bummed when I couldn’t find any resolver information in Ohai data. I needed to make some changes to an nginx config to use resolver, but wanted to use the resolver that’s already…

Use X-Forwarded-For in Apache when behind a proxy

Posted on December 18, 2013 by

Ameir Abdeldayem Posted in Tech Corner — No Comments ↓

I love Apache. I love nginx. I love them when they’re alone, and I love them when they’re together. But when they’re together, sometimes they don’t play nice. When behind a proxy, Apache will use the proxy’s IP address in…

Specify multiple redundant Vagrant box URLs

Posted on December 7, 2013 by

Ameir Abdeldayem Posted in Tech Corner — No Comments ↓

Vagrant is awesome, but there are times where you might need to specify redundant/alternative URLs in a Vagrantfile. This could be a failover type scenario, although in my case, I needed it to give external developers access to our Vagrantbox,…

Ameir Abdeldayem Posted in Tech Corner — 2 Comments ↓

When working on a WordPress project recently where speed was a huge concern, I relied on everyone’s favorite reverse proxy, Nginx, to offload the work required by Apache to serve pages. This worked great, but an issue I encountered was…

Bing Site Search in PHP with Pagination

This is a simple yet powerful way to get Bing’s Site Search API working on your site in PHP. Simply update the $config variables below and you’ll be good to go.

<?php
define('TITLE', 'Search Results');
include('header.php');

$config['appid'] = "01234567890"; // change this
$config['search_domains'] = array("domain1.com", "domain2.com");
$config['results_per_page'] = 20;

$url = "http://$_SERVER[HTTP_HOST]$_SERVER[PHP_SELF]";
?>

<?php echo (isset($_REQUEST['q']) ? "<h1>Search Results</h1>" : "<h1>Search</h1>"); ?>
<form method="get">
    <div style="text-align:right">
        <input type="text" id="q" name="q" value="<?php echo (isset($_REQUEST['q']) ? $_REQUEST['q'] : 'Search...'); ?>"/>
        <input type="submit" value="Search" name="submit" id="searchButton" />
    </div>
</form>

<?php
if (isset($_REQUEST ['q'])) {
    $query = htmlentities($_REQUEST ['q']);
    if (strlen($query) < 1)
        echo "You didn't type anything!";
    else {
        if (isset($_REQUEST ['page'])) {
            $page = htmlentities($_REQUEST ['page']);
            $offset = (($page - 1) * $config['results_per_page']);
        } else
            $offset = 0;

        $result = "http://api.search.live.net/json.aspx?Appid={$config['appid']}&sources=web";
        $result .= "&query=" . urlencode("site:" . implode(" OR site:", $config['search_domains']) . " " . $query);

PHP Function to Return Lowest MX Record

Posted on October 1, 2010 by

Ameir Abdeldayem Posted in Tech Corner — No Comments ↓

This is a quick and simple one, but I admittedly started off with a for loop before coming across array_multisort. This turned out to be very useful for an application I’m working on.

// example
echo "Google's lowest MX is: " . lowestmx("google.com");

function lowestmx($server) {
getmxrr($server, &amp;$mxhosts, &amp;$weight);
array_multisort($weight, $mxhosts);
return $mxhosts[0];
}

// example

echo "Google's lowest MX is: " . lowestmx("google.com");

function lowestmx($server) {

getmxrr($server, &$mxhosts, &$weight);

array_multisort($weight, $mxhosts);

return $mxhosts[0];

}
