in_array problem

[peterdays]

here is the code

print_r(array_values($resultfaceoffs));


if (in_array("0", $resultfaceoffs[opponent_id])) 
	{
	echo "<br><br>yes";
	}
	else
	{
	echo "<br><br>no";
	}

the array:

Array
(
    [0] => Array
        (
            [0] => 1
            [faceoff_id] => 1
            [1] => 0
            [player_id] => 0
            [2] => 0
            [opponent_id] => 0
            [3] => 1
            [races] => 1
        )

[1] => Array
    (
        [0] => 2
        [faceoff_id] => 2
        [1] => 0
        [player_id] => 0
        [2] => 0
        [opponent_id] => 0
        [3] => 1
        [races] => 1
    )

[2] => Array
    (
        [0] => 3
        [faceoff_id] => 3
        [1] => 0
        [player_id] => 0
        [2] => 0
        [opponent_id] => 0
        [3] => 1
        [races] => 1
    )

[3] => Array
    (
        [0] => 4
        [faceoff_id] => 4
        [1] => 0
        [player_id] => 0
        [2] => 0
        [opponent_id] => 0
        [3] => 1
        [races] => 1
    )

)
<br><br>no

i cant seem to find the 0 or "0" in the array, probably because i am not searching on the right array, what am i doing wrong?

[dagon]

which 0 did you expect to find? in_array finds values in a 2d array, in your case every value is another array.

[peterdays]

i want to see if any of those arrays have the [opponent_id] field with a 0

[dagon]

		foreach($resultfaceoffs as $k=>$v){

		if($v['opponent_id'] == '0'){
			echo "<br><br>yes";
		}

	}

[peterdays]

foreach($resultfaceoffs as $k=>$v)
	{

	if($v[opponent_id] == '0')
		{
		echo "<br><br>yes";
		}
		else
		{
		echo "<br><br>no";
		}
} 

i still get a no

[dagon]

i get yes, no as i would expect.

$resultfaceoffs=array(array('opponent_id'=>'0','b'),array('c','d'));

foreach($resultfaceoffs as $k=>$v)
    {

    if($v[opponent_id] == '0')
        {
        echo "<br><br>yes";
        }
        else
        {
        echo "<br><br>no";
        }
}
