PHP多维数组搜索key等于并返回main key

你可以用 array_filter 要从数据创建新数组,请执行以下操作:

$data = [['id' => 1, 'data' => 42, 'archived' => false],
         ['id' => 2, 'data' => 43, 'archived' => true]];
$filtered = array_filter($data, function ($var){ return !$var['archived'];});

$aInner

$aArray = array(
    0 => array('id' => 1242, 'name' = "John", 'archived' => 1),
    1 => array('id' => 1342, 'name' = "Ben", 'archived' => 0)
);

// loop over each element in the array, if its set using the current iPos, unset the key from array
foreach ($aArray as $iPos => $aInner) {
    if($aInner['archived'] === 1){
        unset($aArray[$iPos]);
        continue;        
    }
}

你可以用 array_filter 要创建满足您的条件的新阵列,例如:

$items = array_filter($arr, function($value, $key) {
    return $value['archived'] !== 1
}, ARRAY_FILTER_USE_BOTH);
