PHP 将二维数组转成一维数组 键名保持不变 并且去掉空元素

PHP code

array(    0=>array(        'zhangsan' => 'zhangsan (dae) abc'    )    1=>array(        'lisi' => 'lisi (dae) abc'    )               2=>array())转成array(    'zhangsan' => 'zhangsan (dae) abc',    'lisi' => 'lisi (dae) abc',)

PHP code

$a = array(    0=>array(        'zhangsan' => 'zhangsan (dae) abc'    ),    1=>array(        'lisi' => 'lisi (dae) abc'    ),    2=>array());$list = array();foreach ($a as $v) {    if (!$v) {        continue;    }    $list[key($v)] = $v[key($v)];}
