PHP数组排序的问题
有两个数组如下:
$aray1 = ( 'key3' => 'value3', 'key2' => 'value2', 'key1' => 'value1 ); $aray2 = ('key1', 'key3', 'key2'); //看清楚了,顺序不是123哦
请问php有没有内置的函数可以通过$array2将$array1排序成如下格式:
$aray1 = ( 'key1' => 'value1', 'key3' => 'value3', 'key2' => 'value2 );
我看了下array_multisort()的文档,但是好像不支持。

貌似没有,array_multisort()主要是对多维数组排序
用用户自定义排序函数usort(),不过还是要自己写
<code>foreach($array2 as $i => $key) { $result[$key] = $array1[$key]; } var_dump($result);</code>
$data = array(); array_walk($aray2,function($value, $key) use($aray1, &$data){ $data[$value] = $aray1[$value]; }); print_r($data);
根据我的经验,是没有这样的内部函数的
可以自己写一个方法
可以自己写一个方法
自己写一个呗
只有自己根据排序规则写一个了
