OOP PHP Vimeo Class

This is essentially the earlier mentioned RSS class with a couple of tweaks for vimeo and search.

First, a script to call the class:

<?php
require_once 'vimeo.class.php';

$addr1 = 'http://vimeo.com/api/v2/channel/videoschool/videos.xml';
$addr2 = 'http://vimeo.com/api/v2/channel/wineaftercoffee/videos.xml';

$vimeo = new vimeo;
$vimeo->addFeed($addr1);
$vimeo->addFeed($addr2);

$arr = $vimeo->getFeed();

/* Or
$arr = $vimeo->getFeed('water');
*/

/*
Or
$searchArray = Array('glass', 'trix');
$arr = $vimeo->getFeed($searchArray);
*/

foreach($arr as $row)
{
echo '<iframe src="http://player.vimeo.com/video/'.$row->id.'" width="WIDTH" height="HEIGHT" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe><br />';
}
?>

Now, the class itself:


<?php
class vimeo
{
public $addr = NULL;
private $outArr = Array();
function __construct($addr = NULL)
{
$this->addr = $addr != NULL ? $addr : $this->addr;
if($this->addr)
{
return $this->addFeed();
}
}

function addFeed($addr = NULL)
{
$this->addr = $addr != NULL ? $addr : $this->addr;
$rss = simplexml_load_file($this->addr);
$this->outArr = array_merge($this->outArr, $rss->xpath('/videos//video'));
}

function getFeed($input = NULL)
{
usort($this->outArr, function ($x, $y)
{
if (strtotime($x->pubDate) == strtotime($y->pubDate)) return 0;
    return (strtotime($x->pubDate) > strtotime($y->pubDate)) ? -1 : 1;
});

if(is_array($input))
{
$this->outArr = $this->getArrayFilteredFeed($input);
}
elseif(is_string($input))
{
$this->outArr = $this->getStringFilteredFeed($input);
}

return $this->outArr;
}

private function getStringFilteredFeed($s)
{
$tempArr = Array();
foreach($this->outArr as $row)
{
if(stristr($row->title,$s) || stristr($row->description,$s))
{
array_push($tempArr, $row);
}
}
return $tempArr;
}

private function getArrayFilteredFeed($arr)
{
$tempArr = Array();
foreach($this->outArr as $row)
{
foreach ($arr as $key) 
{
if(stristr($row->title,$key) || stristr($row->description,$key))
{
array_push($tempArr, $row);
}
}
}
return $tempArr;
}
}
?>
