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 ) )
