How to use in_array() to check if an associative row exists in another array of associative arrays

I'm passing data from my controller to view, I have code in my view

foreach ($mapData as $map)
{
 echo $map['x'].';'.$map['y'].'<br/>';
}

And it prints me something like

5;5
6;6
7;7

Now, I am passing another data from my database as a two-dimensional array which looks like something like this

Array
(
[0] => Array
    (
        [x] => 5
        [y] => 4
    )

[1] => Array
    (
        [x] => 5
        [y] => 5
    )

)

I want to check if any of $map['x'] and $map['y'] exists in that array so I am doing (Don't know any other way because I need to check this in foreach loop)

if (in_array(array($map['x'], $map['y']), $array)) {
echo 1;
}

But it doesn't work and according to http://php.net/manual/en/function.in-array.php it should work? What am I doing wrong?

Array
(
[0] => Array
    (
        [x] => 5
        [y] => 4
    )

[1] => Array
    (
        [x] => 5
        [y] => 5
    )

)

should look like

Array
(
[0] => Array
    (
        [0] => 5
        [1] => 4
    )

[1] => Array
    (
        [0] => 5
        [1] => 5
    )

)

That means, $array (i.e. haystack) should not be an array with different indexing than neddle.

You are passing index x and y as haystack. But in needle you are just passing like array(5,5) or array(6,6) and so on.

According to doc, in_array() can compare

in_array( array(5,5), array( array(5,5), array(6,6) ) )

but not

in_array( array(5,5), array( array('x' =>5, 'y' => 5), array('x' => 6, 'y' => 6) ) )
