好的,我已经在stackoverflow中遇到了这个问题,但遗憾的是它在
javascript –
Javascript – sort array based on another array中
我想在PHP中
- $data = array(
- "item1"=>"1","item2"=>"3","item3"=>"5","item4"=>"2","item5"=>"4"
- );
匹配这个数组的排列：
- sortingArr = array("5","4","3","2","1");
和我正在寻找的输出：
- $data = array(
- "item3"=>"5","item5"=>"4","item1"=>"1"
- );
任何想法怎么可以做到这一点？
谢谢.
很简单
- $data = array(
- "item1"=>"1","item5"=>"4"
- );
- $sortingArr = array("5","1");
- $result = array(); // result array
- foreach($sortingArr as $val){ // loop
- $result[array_search($val,$data)] = $val; // adding values
- }
- print_r($result); // print results
输出：
- Array
- (
- [item3] => 5
- [item5] => 4
- [item2] => 3
- [item4] => 2
- [item1] => 1
- )
