I've been looking a lot of answers, but none of them are working for me.
This is the data assigned to my $quantities
array:
Array(
[10] => Array([25.00] => 1)
[9] => Array([30.00] => 3)
[8] => Array([30.00] => 4)
[12] => Array([35.00] => )
[1] => Array([30.00] => )
[2] => Array([30.00] => )
)
I'm looking for a way to remove the subarrays with empty values like [12]
[1]
and [2]
while keeping everything else.
The desired result:
Array(
[10] => Array([25.00] => 1)
[9] => Array([30.00] => 3)
[8] => Array([30.00] => 4)
)
I tried a lot of the functions on the official php docs and none of them worked.
I've used this one:
function array_filter_recursive($array, $callback = null) {
foreach ($array as $key => & $value) {
if (is_array($value)) {
$value = array_filter_recursive($value, $callback);
} else {
if ( ! is_null($callback)) {
if ( ! $callback($value)) {
unset($array[$key]);
}
} else {
if ( ! (bool) $value) {
unset($array[$key]);
}
}
}
}
unset($value);
return $array;
}
But it only removes the element in the subarrays; I need the subarrays to be removed entirely.
I don't want this:
Array(
[10] => Array([25.00] => 1)
[9] => Array([30.00] => 3)
[8] => Array([30.00] => 4)
[12] => Array()
[1] => Array()
[2] => Array()
)
Bit late, but may help someone looking for same answer. I used this very simple approach to;
$postArr = array_map('array_filter', $postArr);
$postArr = array_filter( $postArr );
