Finding the smallest value in an array without looping through? (PHP)

I have this array:

$myArray = array("0x40x40" => 64, "0x50x40" => 65, "0x60x40" => 66);

Now I want to find the smalles value, in this case its 64 (the first key/value pair). Is there a way other than looping through the array and to compare the values? The smallest value is not always the first and the values are not sorted by the way.

Thanks!

If you only needs the lowest or highest value

$myArray = array( "0x40x40" => 64, "0x50x40" => 65, "0x60x40" => 66 ); 
asort ( $myArray );
$item = current( $myArray );

This is for lowest to highest, in reverse U would need the arsort() function

$myArray = array(
        "0x40x40" => 64, 
        "0x50x40" => 65, 
        "0x60x40" => 66,

Using min:

$myArray = array(
    "0x40x40" => 64, "0x50x40" => 65, "0x60x40" => 66, "0x70x40" => 67, "0x80x40" => 68, "0x90x40" => 70, "0x100x40" => 71, "0x110x40" => 74, "0x120x40" => 76);

echo min($myArray);

You can use the min() function to get your answer nicely.

echo min(2, 3, 1, 6, 7); // 1

or

$myArray=array(2, 3, 1, 6, 7);
echo min($myArray); // 1
