Question

如题所述

Answer 1

<?php
$array1=array(1, 2);//数组1
$array2=array(2, 3);//数组2
$array3=array_merge($array1, $array2);//合并数组;
$array3=array_unique($array3);//移除数组中重复的值
?>

Answer 2

<?php
$arr1=array("a","b","c");
$arr2=array("c","d","e");
$myarray=array_merge($arr1,$arr2);
print_r($myarray);
$myarray=array_unique($myarray);
print_r($myarray);
?>

Answer 3

<?php
$arr1=array("a","b","c");
$arr2=array("c","d","e");

$myarray=array_merge($arr1,$arr2);
print_r($myarray);

$myarray=array_unique($myarray);

print_r($myarray);
