Ordering an array via an element with an array

[Maxoplata]

basically I have an array that looks something like this:

$myarray = array();
$myarray[0] = array("5", "3", "6", "1", "3");
$myarray[1] = array("1", "8", "4", "2", "0");
$myarray[2] = array("9", "1", "0", "0", "5");
$myarray[3] = array("8", "7", "1", "5", "6");
$myarray[4] = array("0", "2", "4", "7", "9");
$myarray[5] = array("5", "5", "5", "7", "5");

 

I would like to sort the array so I can print out the data in a table, but I want to sort the array by the first value (0) in the inner array (so it would print out in the order 2,3,0,5,1,4). Can anyone help me figure this out? (In the long run I would like to order by 0,1,3 for when values are the same but just ordering by 0 will work for me for now).

Hi,

 

with array_multisort() e.g. like this:

 

       

        $myarray = array();
        $myarray[0] = array("5", "3", "6", "1", "3");
        $myarray[1] = array("1", "8", "4", "2", "0");
        $myarray[2] = array("9", "1", "0", "0", "5");
        $myarray[3] = array("8", "7", "1", "5", "6");
        $myarray[4] = array("0", "2", "4", "7", "9");
        $myarray[5] = array("5", "5", "5", "7", "5");

        $myarray_sort = array();
        foreach ($myarray as $arr)
        {
            $myarray_sort[] = $arr[0];
        }

        array_multisort($myarray, $myarray_sort);

        print_r($myarray);
