我想给每个值,都添加一个元素c => 3,不用foreach可以吗,有没有系统函数啊
$ary = 
Array
(
    [0] => Array
        (
            [a] => 1
            [b] => 2    
        )
    [1] => Array
        (
            [a] => 1
            [b] => 2    
        )
    ...
)
目标:
Array
(
    [0] => Array
        (
            [a] => 1
            [b] => 2  
    [c] => 3 
        )
    [1] => Array
        (
            [a] => 1

)


回复讨论(解决方案)

先foreach大数组,然后foreach里面 array_push。

不想用foreach啊。

我尝试用array_pad,但只会填充,不能增加。。。

$ary = array(  array( 'a' => 1, 'b' => 2 ),      array( 'a' => 1, 'b' => 2 ),      array( 'a' => 1, 'b' => 2 ),    );//方法一$res = array_map('array_merge', $ary, array_fill(0, count($ary), array('c' => 3)));print_r($res);//方法二function foo2(&$v) {  $v['c'] = 3;}$res = $ary;array_walk($res, 'foo2');print_r($res);//方法三function foo3(&$v, $k, $param) {  $v = array_merge($v, $param);}$res = $ary;array_walk($res, 'foo3', array('c' => 3));print_r($res);/*** php5.3以后还可以用闭包 **/
