本文实例讲述了php实现给二维数组中所有一维数组添加值的方法。分享给大家供大家参考，具体如下：

给二维数组中所有的一维数组添加值(索引和关联)

$shop = array(
 0=>array(0=>1,1=>2,2=>3,3=>4)
 ,1=>array(0=>1,1=>2,2=>3)
 ,2=>array(0=>1,1=>2,2=>3)
 );
print_r($shop);
//示例 1:引用循环变量的地址赋值
foreach($shop as &$shoplist){
 $shoplist[] = '4444444444444';
 $shoplist['we'] = '欢迎光临脚本之家';
}
print_r($shop);

运行结果：

Array (
[0] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 4444444444444 [we] => 欢迎光临脚本之家 )
[1] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4444444444444 [we] => 欢迎光临脚本之家 )
[2] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4444444444444 [we] => 欢迎光临脚本之家 )
)

//示例2:修改循环变量数组,重新赋值
foreach($shop as $key=>$shoplist){
 $index = count($shoplist);
 $shoplist[$index] = '4444444444444';
 $shoplist['we'] = '欢迎光临脚本之家';
 $shop[$key]=$shoplist;
}
print_r($shop);

运行结果：

Array (
[0] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 4444444444444 [we] => 欢迎光临脚本之家 )
[1] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4444444444444 [we] => 欢迎光临脚本之家 )
[2] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4444444444444 [we] => 欢迎光临脚本之家 )
)
