first element in an array for a specific value?

[duckduckgoose]

I'm trying to build array based on the first instance of a value in another array...

A minified example of the array:

Array (
    [0] => Array(
            id => 1
            name => Miller
            )
    [1] => Array(
                id => 4
                name => Miller
            )
    [2] => Array(
                id => 2
                name => Smith
    [3] => Array(
                id => 7
                name => Jones
            )
    [4] => Array(
                id => 9
                name => Smith
            )
)

So, I want to create this array:

Array (
    [0] => Array(
            id => 1
            name => Miller
            )
    [2] => Array(
                id => 2
                name => Smith
    [3] => Array(
                id => 7
                name => Jones
            )
)

I tried the following, but it's still just returning everything...

$sorted = array();
$i = 0;
        foreach($myarray as $pk => $pv) {
                if(!in_array($pv['name'], $sorted)) {
                    $sorted[$i]['id'] = $pv['id'];
                    $sorted[$i]['name'] = $pv['name'];
                }
                $i++;
        }

$mainArr[] = $innner;

$innner['id'] = 4;

$mainArr[] = $innner;

$innner['id'] = 2;

$mainArr[] = $innner;

$innner['id'] = 7;
$innner['name'] = 'Jones';
$mainArr[] = $innner;

$innner['id'] = 9;
$innner['name'] = 'Smith';
$mainArr[] = $innner;


$mainCnt = count($mainArr);
$tempArr = null;

for($i=0;$i < $mainCnt;$i++)
{
	$inn = $mainArr[$i];

if(is_null($tempArr))
	$tempArr[] = $inn;		
else
{		
	$exists = false;		
	$tmpCnt = count($tempArr);			

	for($x=0; $x < $tmpCnt;$x++)
	{
		if(strtolower($tempArr[$x]['name']) == strtolower($inn['name']))
		{
			$exists = true;
			break;
		}
	}

	if(!$exists)
	{
		$tempArr[] = $inn;
	}
}
}

print '<pre>';
print_r($tempArr);
print '</pre>';
