如果数组中有数组,如何删除外部数组:

$outer_array = array(0 => array(
                                'key1' => 'value1',
                                'key2' => 'value2'
     ));

print_r($ outer_array)产生:

Array
(
    [0] => Array
        (
            [key1] => value1
            [key2] => value2
        )

)

是否有一个内置于PHP的功能,所以你留下:

        Array
        (
            [key1] => value1
            [key2] => value2
        )
