我有這個數(shù)組結(jié)構(gòu)。如果我發(fā)現(xiàn)[empevalpptwo]空或空，我試圖刪除那些整個數(shù)組，所以如果它[empevalpptwo]是空的，整個數(shù)組[4] => Array應(yīng)該被刪除?，F(xiàn)在我只是想獲取父索引，所以我可以按索引刪除它有沒有像遞歸過濾這樣的好的解決方案？$kra = array_column($ppform_plan->toArray(), 'kra');$emp_eval_pptwo = array_search('', array_column($kra, 'empevalpptwo'));//should return 4Array( [4] => Array ( [id] => 50 [user_id] => 6282 [specific_user_id] => 6281 [eval_cat_id] => 2 [format_cat] => 1 [title] => This istesting [desc] => [weight] => 50 [bsc_weight_group] => [bsc_rating] => [sequence] => [created_at] => 2019-05-22 10:55:23 [updated_at] => 2019-05-22 10:55:23 [kra] => Array ( [0] => Array ( [id] => 77 [user_id] => 6282 [bsc_id] => 50 [index] => 0 [kra_title] => ttes lang muna [kra_desc] => [kra_weight] => 25 [sat] => 521 [at] => 4 [ot] => 535 [rating_per_kra] => [rating_per_kra_cat] => [net_weighting] => 5 [rank] => 1 [remarks] => [indicator_text] => [created_at] => [updated_at] => [empevalpptwo] => ) ) ) ))

類似于：
<?php
$items =
[
1 =>
[
'foo'=>
[
[
'bar' => '',
],
[
'bar' => '',
]
]
],
2 =>
[
'foo'=>
[
[
'bar' => 'baz'
]
]
]
];
foreach ($items as $k => $item)
if(empty(array_filter(array_column($item['foo'], 'bar'))))
unset($items[$k]);
var_export($items);
輸出：
array (
2 =>
array (
'foo' =>
array (
0 =>
array (
'bar' => 'baz',
),
),
),
)
