数组组合

Question

原数组$username = array(username=>张三);
$username = array(username=>张二);
$username = array(username=>张一);目标数组$username = array(张三,张二,张一);
用PHP怎么将原数组改成目标数组啊?

Answer 1

<?php
$username1 = array('username'=>'张三');
$username2 = array('username'=>'张二');
$username3= array('username'=>'张一');$i = 1;
$name = "username";
$result =array();
for($i=1;$i<=3;$i++){
   $result[]= ${$name.$i}['username'];
}print_r($result);

Answer 2

$username1 = array('username'=>'张三');
$username2 = array('username'=>'张二');
$username3= array('username'=>'张一');$newarray=array_merge_recursive($username1,$username2,$username3);
$newarray=$newarray['username'];
print_r($newarray);
