Meaning, you cycle through your array with a foreach loop, if you find that an element is not set (isset() is false), you unset() that element. It is then destructed/removed from the array :-) — Werner, Feb 12 '16 at 10:37

You can use array_map and array_filter functions for removing empty values from multi-dimensional array.

Solution:

$array = array_filter(array_map('array_filter', $yourArr));

Example:

$yourArr[12] = array('12','Philippines');
$yourArr[13] = array('','');
$array = array_filter(array_map('array_filter', $yourArr));

echo "<pre>";
print_r($array);

Result:

Array
(
    [12] => Array
        (
            [0] => 12
            [1] => Philippines
        )

)

Use array_map() and array_filter()

$result = array_map('array_filter', $a)

array_filter() removes blank elements from array in this case.

array_map() function calls a function on every array element, in this cause, it calls array_filter() and removes empty elements.

Working Code:

<?php
$a = array(12 => array(12, 'Philippines', '94,013,200', 'Mid-2010', '0.0136'), 13 => array('', '', '', '', ''));
$result = array_map('array_filter', $a);
echo "<pre>";
print_r($result);
echo "</pre>";
?>
