Here is fast and easy way to install Git on Centos 5.7.

1. Get the EPEL release for Centos 5.

2. Install git, git-daemon using yum

sudo /usr/local/mysql/support-files/mysql.server restart

Version #1 use a simple array

$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToFilter('sku', array('n2610','bb8100'));


$items = $collection->getItems();
echo count($collection);

Version #2 use a more specific array

$collection = Mage::getModel('catalog/product')->getCollection();

$collection->addAttributeToFilter(
 array(
 array('attribute'=>'sku','eq'=>"n2610"),
 array('attribute'=>'sku','eq'=>"bb8100")
 ));

$items = $collection->getItems();
echo count($collection);

If you ever were curious about what the SQL is being built for a Magento Collection, its really, really easy

$collection = Mage::getModel('poll/poll')->getResourceCollection()
 ->addFieldToFilter('date_posted', array('from' =>'2014-02-01 00:00:00', 'to'=>'2014-02-28 23:59:59'));
$collection->load(true);

The result will be something similar to this:

SELECT `main_table`.* FROM `poll` AS `main_table` WHERE (date_posted >= '2014-02-01 00:00:00' AND date_posted <= '2014-02-28 23:59:59')

One day, I was at work and a friend of mine was trying to recall what his Master lock combination was.  He knew the first and last number.  I had done a bit of googling and found that if you know the last number of the combination, there is a defined set of possible options!  This was promising.  After figuring out the algorythm, I set forth on a quest to provide a nice template for him to use when doing the recovery.  It turns out that there are only 100 possible combination should you know that last number.

When building admin area modules, you need to sometimes use the admin users. When doing so, you may want to combine the firstname and lastname into one. This is where concat comes in handy. It will combine them, into one string to be used as the visual for the dropdown. The following function will also show you how to get all the admin users using a collection.

    /*
    *  
    */
    public function getAdminUsersAsOptions()
    {

        $collection = Mage::getModel('admin/user')->getCollection()
                            ->addFieldToSelect('firstname')
                            ->addFieldToSelect('lastname')
                            ->addFieldToSelect('user_id');
        $collection->setOrder('lastname', 'ASC');
        $fields      = array('lastname', 'firstname');
        $fieldConcat = $collection->getConnection()->getConcatSql($fields, ', ');

        $collection->getSelect()->columns(array('value'=> 'user_id', 'name' => $fieldConcat));
        $items = $collection->getItems();
        $user_array = array();
        foreach($items as $_user)
        {
            $user_array[$_user->getData('user_id')] = $_user->getData('name');
        }
        return $user_array;
    }
