Prevent Blanks in Array

[jarvis]

Hi,

How do you prevent the following happening:

Array
(
    [] => Array

So, effectively I want to remove that one from the main array. i.e.

Array
(
    [] => Array
        (
            [0] => Japanese GP
            [1] => Japanese GP
            [2] => Williams
        )

    [2005] => Array
        (
            [0] => Japanese GP
            [1] => Williams
        )

    [2006] => Array
        (
            [0] => Japanese GP
        )

)

Becomes: 

Array
(

    [2005] => Array
        (
            [0] => Japanese GP
            [1] => Williams
        )

    [2006] => Array
        (
            [0] => Japanese GP
        )

)

I tried using:

if (!empty($year['value'])):

Within my foreach but sadly that didn't work

 

Thanks

use array_filter() with the

• ARRAY_FILTER_USE_KEY

flag set.

EDIT: Of course the easiest method is not to put data into the array that you then want to remove

PS If you prefer to use a foreach loop then

$result = [];
foreach ($array as $k => $v) {
    if ($k) {
        $result[$k] = $v;
    }
}

For anyone who's interested, the code would be

$result = array_filter($array, function($v) {return $v;}, ARRAY_FILTER_USE_KEY);
