How to get minimum value of an array?

Trying to get back into coding, and I'm currently working on a new project. Let me get right to the chase.

Lets say I have an array:
[3017496] => 15
[3017678] => 9
[3017114] => 8
[3017297] => 10
[3017428] => 9
[3017440] => 6
[3017683] => 5
[3017306] => 11
[3017461] => 8
[3017529] => 6
[3017683] => 5

I'm trying to return the minimum values of this array. min() work pretty well, but it only returns an number, and it doesn't discriminate over how many of the lowest value there are.

Taking that array as an example, min() only returns 5. However, I need this:

[3017683] => 5
[3017683] => 5

I could always just make a foreach function and compare all the values while throwing out ones higher than others until it comes down to what I need, but I wanted to ask here to see if there's already a function to do this.

Thanks!

Not the most elegant solution but will work for what you explained, I'm assuming the values will always be numeric so I set strict comparison to true.


$test_array = array(3017496 => 15, 3017683 => 5, 3017306 => 11, 3017623 => 5, 3017114 => 8);
$min_val = min($test_array);
$arr_search = array_keys($test_array, $min_val, true);
print_r($arr_search);

function min_values( Array $array )
{
return
array_intersect_key(
$array,
array_count_values(
array_keys(
$array,
min( $array )
)
)
);
}

// usage
$min_values = min_values( $values );

Thank you all for the help. =)
