>我得到一个看起来像这样的数组
Array
(
[0] => Array
(
[CAT] => CAT
[2] => 1
)
[1] => Array
(
[DOG] => DOG
[3] => 1
)
[2] => Array
(
[CAT] => CAT
[4] => 1
)
)
但我想要的是这样的安慰
Array
(
[0] => Array
(
[CAT] => CAT
[2] => 1
[4] => 1
)
[1] => Array
(
[DOG] => DOG
[3] => 1
)
)
我以一种保存密钥和所有内容的方式创建了它。让我知道它是否适合你:)
<?php
$start = [
["cat" => "cat", "2" => 1],
["dog" => "dog", "3" => 1],
["cat" => "cat", "4" => 1]
];
$end = [];
foreach($start as $key => $array) {
if(!isset($end[current($array)])) {
$name = current($array);
$end[$name][key($array)] = $name;
next($array);
$end[$name][key($array)] = current($array);
} else {
$name = current($array);
next($array);
$end[$name][key($array)] = current($array);
}
}
$end = array_values($end);
print_r($end);
