PHP：合并/添加多维数组？

导读： 假设我有几个具有相同结构的多维数组,如下所示：
$basketA['fruit']['apple'] = 1;
$basketA['fruit']['orange'] = 2;
$basketA['fruit']['bana
$basketA['fruit']['apple'] = 1;
$basketA['fruit']['orange'] = 2;
$basketA['fruit']['bana

假设我有几个具有相同结构的多维数组,如下所示： $basketA['fruit']['apple'] = 1; $basketA['fruit']['orange'] = 2; $basketA['fruit']['banana'] = 3; $basketA['drink']['soda'] = 4; $basketA['drink']['milk'] = 5; $basketB['fruit']['apple'] = 2; $basketB['fruit']['orange'] = 2; $basketB['fruit']['banana'] = 2; $basketB['drink']['soda'] = 2; $basketB['drink']['milk'] = 2 我需要一种方法来合并它们,所以我会得到这个： $basketC['fruit']['apple'] = 3; $basketC['fruit']['orange'] = 4; $basketC['fruit']['banana'] = 5; $basketC['drink']['soda'] = 6; $basketC['drink']['milk'] = 7; 真正的多维数组会更复杂,这只是为了帮助解释我需要的东西. 谢谢！！！！ 解决方法: 使用PHP的标准方法是不可能的,你应该编写自己的函数： 码 function readArray( $arr, $k, $default = 0 ) { return isset( $arr[$k] ) ? $arr[$k] : $default ; } function merge( $arr1, $arr2 ) { $result = array() ; foreach( $arr1 as $k => $v ) { if( is_numeric( $v ) ) { $result[$k] = (int)$v + (int) readArray( $arr2, $k ) ; } else { $result[$k] = merge( $v, readArray($arr2, $k, array()) ) ; } } return $result ; } 测试 $basketA = array( "fruit" => array(), "drink" => array() ) ; $basketA['fruit']['apple'] = 1; $basketA['fruit']['orange'] = 2; $basketA['fruit']['banana'] = 3; $basketA['drink']['soda'] = 4; $basketA['drink']['milk'] = 5; $basketB = array( "fruit" => array(), "drink" => array() ) ; $basketB['fruit']['apple'] = 2; $basketB['fruit']['orange'] = 2; $basketB['fruit']['banana'] = 2; $basketB['drink']['soda'] = 2; $basketB['drink']['milk'] = 2; $basketC = merge( $basketA, $basketB ) ; print_r( $basketC ) ; 产量 Array ( [fruit] => Array ( [apple] => 3 [orange] => 4 [banana] => 5 ) [drink] => Array ( [soda] => 6 [milk] => 7 ) ) 总结 以上是编程之家为你收集整理的PHP：合并/添加多维数组？全部内容PHP多维数组，希望文章能够帮你解决PHP：合并/添加多维数组？所遇到的程序开发问题。 如果觉得编程之家网站内容还不错，欢迎将编程之家网站推荐给程序员好友。 （编辑：百客网 - 百科网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
