如何在三维数组上运行array_map？我想在哪里"清除"最里面的阵列？
它看起来像这样：
Array
(
[1] => Array
(
[1] => Array
(
[cat] => Hello!
[url] => hello
)
[5] => Array
(
[cat] => Good job!
[url] => good-job
)
[2] => Array
(
[2] => Array
(
[cat] => How are you?
[url] => how-are-you
)
[6] => Array
(
[cat] => Running shoes
[url] => running-shoes
)
)
)
我想让它看起来像这样：
Array
(
[1] => Array
(
[1] => Array
(
[cat] => Hello!
[url] => hello
)
[2] => Array
(
[cat] => Good job!
[url] => good-job
)
[2] => Array
(
[1] => Array
(
[cat] => How are you?
[url] => how-are-you
)
[2] => Array
(
[cat] => Running shoes
[url] => running-shoes
)
)
）
这个解决方案 在 php 中重置数组元素的键？"只是"适用于拖曳式阵列，如果我没错的话。
你可以写一个简短的函数来使用它array_map：
function mappingfunction($array){
$remappedarray = array();
foreach($array as $layer){
$remappedarray[] = array_map('array_values', $array);
}
return $remappedarray;
}
如果要保留密钥：
function mappingfunction($array){
$remappedarray = array();
foreach($array as $key => $layer){
$remappedarray[$key] = array_map('array_values', $array);
}
return $remappedarray;
}
未经测试，但应该为您指明正确的方向。
