php如何将两个数组去重后合并

php如何将两个数组去掉重复后合并，下面web建站小编给大家详细介绍一下实现代码！

数组去重

<?php
$arr1=array("a"=>"red","b"=>"green","c"=>"red");
$arr2=array("1"=>"Cat","2"=>"Dog","3"=>"Cat","4"=>"rabbit");
$Narr1=array_unique($arr1);
$Narr2=array_unique($arr2);
var_dump(array_unique($Narr1));
var_dump(array_unique($Narr2));
?>

数组合并

var_dump(array_merge_recursive($Narr1,$Narr2));
