PHP数组按数组内的值删除

Question

There is an array of airports that gets filled with a user list.

    $airport_array[$airport_row['airportICAO']]    = array(
        'airportName' => $airport_row['airportName'],
        'airportCity' => $airport_row['airportCity'],
        'airportLat' => $airport_row['airportLat'],
        'airportLong' => $airport_row['airportLong'],
        'airportUserCount' => 0,
        'airportUserList' => array()
    );

After filling, "airportUserCount" will either be 0 or higher than 1. Now, I want to remove all airports from the array where airportUserCount is set to 0. What is the most performant way to do it? I thought about a foreach loop but I fear it's not necessarily the most elegant solution.

Answer 1

foreach loop, check for the ones that have the Count == 0 then remove them from the array.

$result = array();

foreach ($airport_array[$airport_row['airportICAO']] as $arrays)
{
    if($arrays['airportUserCount'] == 0) {
        array_push($result, $arrays);
    }

}
