php实现给二维数组中所有一维数组添加值的方法

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';
  $shoplist['we'] = '欢迎光临三水点靠木';
}
print_r($shop);

运行结果：

Array (
[0] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 4444444444444 [we] => 欢迎光临三水点靠木 )
[1] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4444444444444 [we] => 欢迎光临三水点靠木 )
[2] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4444444444444 [we] => 欢迎光临三水点靠木 )
)

//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'] = '欢迎光临三水点靠木';
  $shop[$key]=$shoplist;
}
print_r($shop);

运行结果：

Array (
[0] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 4444444444444 [we] => 欢迎光临三水点靠木 )
[1] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4444444444444 [we] => 欢迎光临三水点靠木 )
[2] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4444444444444 [we] => 欢迎光临三水点靠木 )
)

希望本文所述对大家PHP程序设计有所帮助。
