我有一些索引需要从主数组中删除.例如：
$removeIndex=array(1,3,6);
$mainArray=array('1'=>'a','2'=>'b','3'=>'c','4'=>'d','5'=>'e','6'=>'f');
我想要最终结果如：
$mainArray=array('2'=>'b','5'=>'e');
也许尝试array_diff_key：
原文链接：https://www.f2er.com/php/135146.html$removeIndex=array(1,'6'=>'f'); $removeIndex = array_flip($removeIndex);//flip turns values into keys echo '<pre>'; //compute diff between arr1 and arr2,based on key //returns all elements of arr 1 that are not present in arr2 print_r(array_diff_key($mainArray,$removeIndex)); echo '</pre>';
当我尝试这个时,它返回：
Array
(
[2] => b
[4] => d
[5] => e
)
