多个二维数组如何整合到一个数组里

Jun 23, 2016 pm 02:20 PM

二维数组合并

array(7) {
[0]=> array(2) { ["id"]=> string(6) "201307" ["value"]=> int(535) }
[1]=> array(2) { ["id"]=> string(6) "201306" ["value"]=> int(5) }
[2]=> array(2) { ["id"]=> string(6) "201305" ["value"]=> int(758) }
[3]=> array(2) { ["id"]=> string(6) "201304" ["value"]=> int(10) }
[4]=> array(2) { ["id"]=> string(6) "201303" ["value"]=> int(582) }
[5]=> array(2) { ["id"]=> string(6) "201302" ["value"]=> int(390) }
[6]=> array(2) { ["id"]=> string(6) "201301" ["value"]=> int(473) } }

array(7) {
[0]=> array(2) { ["id"]=> string(6) "201307"  ["values"]=> int(3588) }
[1]=> array(2) { ["id"]=> string(6) "201306"  ["values"]=> int(3177) }
[2]=> array(2) { ["id"]=> string(6) "201305" ["values"]=> int(2946) }
[3]=> array(2) { ["id"]=> string(6) "201304" ["values"]=> int(2419) }
[4]=> array(2) { ["id"]=> string(6) "201303" ["values"]=> int(2287) }
[5]=> array(2) { ["id"]=> string(6) "201302" ["values"]=> int(2251) }
[6]=> array(2) { ["id"]=> string(6) "201301" ["values"]=> int(2474) } }

最后想得到

array(7) {
[0]=> array(2) { ["id"]=> string(6) "201307"  ["value"]=> int(535) ["values"]=> int(3588) }
[1]=> array(2) { ["id"]=> string(6) "201306"  ["value"]=> int(5)  ["values"]=> int(3177) }
[2]=> array(2) { ["id"]=> string(6) "201305"  ["value"]=> int(758)["values"]=> int(2946) }
[3]=> array(2) { ["id"]=> string(6) "201304"  ["value"]=> int(10) ["values"]=> int(2419) }
[4]=> array(2) { ["id"]=> string(6) "201303" ["value"]=> int(582) ["values"]=> int(2287) }
[5]=> array(2) { ["id"]=> string(6) "201302" ["value"]=> int(390) ["values"]=> int(2251) }
[6]=> array(2) { ["id"]=> string(6) "201301" ["value"]=> int(473) ["values"]=> int(2474) } }

$a = array( array("id" => "201307", "value" => 535), array("id" => "201306", "value" => 5), array("id" => "201305", "value" => 758), array("id" => "201304", "value" => 10), array("id" => "201303", "value" => 582), array("id" => "201302", "value" => 390), array("id" => "201301", "value" => 473),);$b = array(  array("id" => "201307", "values" => 3588), array("id" => "201306", "values" => 3177), array("id" => "201305", "values" => 2946), array("id" => "201304", "values" => 2419), array("id" => "201303", "values" => 2287), array("id" => "201302", "values" => 2251), array("id" => "201301", "values" => 2474),);$c = array_map('array_merge', $a, $b);print_r($c);

$a = array( array("id" => "201307", "value" => 535), array("id" => "201306", "value" => 5), array("id" => "201305", "value" => 758), array("id" => "201304", "value" => 10), array("id" => "201303", "value" => 582), array("id" => "201302", "value" => 390), array("id" => "201301", "value" => 473),);$b = array(  array("id" => "201307", "values" => 3588), array("id" => "201306", "values" => 3177), array("id" => "201305", "values" => 2946), array("id" => "201304", "values" => 2419), array("id" => "201303", "values" => 2287), array("id" => "201302", "values" => 2251), array("id" => "201301", "values" => 2474),);$c = array_map('array_merge', $a, $b);print_r($c);

Array
(
    [0] => Array
        (
            [id] => 201307
            [value] => 535
            [values] => 3588
        )

    [1] => Array
        (
            [id] => 201306
            [value] => 5
            [values] => 3177
        )

    [2] => Array
        (
            [id] => 201305
            [value] => 758
            [values] => 2946
        )

    [3] => Array
        (
            [id] => 201304
            [value] => 10
            [values] => 2419
        )

    [4] => Array
        (
            [id] => 201303

            [value] => 390
            [values] => 2251
        )

    [6] => Array

            [id] => 201301
            [value] => 473
            [values] => 2474

基础很重要啊。没想到自带的函数都有这些功能。牛。我还想其他的方法去。

array(7) {
[0]=> array(2) { ["id"]=> string(6) "201307" ["value"]=> int(535) }
[1]=> array(2) { ["id"]=> string(6) "201305" ["value"]=> int(758) }
[2]=> array(2) { ["id"]=> string(6) "201304" ["value"]=> int(10) }
[3]=> array(2) { ["id"]=> string(6) "201303" ["value"]=> int(582) }
[4]=> array(2) { ["id"]=> string(6) "201302" ["value"]=> int(390) }
[5]=> array(2) { ["id"]=> string(6) "201301" ["value"]=> int(473) } }

array(7) {
[0]=> array(2) { ["id"]=> string(6) "201307"  ["values"]=> int(3588) }
[1]=> array(2) { ["id"]=> string(6) "201306"  ["values"]=> int(3177) }
[2]=> array(2) { ["id"]=> string(6) "201305" ["values"]=> int(2946) }
[3]=> array(2) { ["id"]=> string(6) "201304" ["values"]=> int(2419) }
[4]=> array(2) { ["id"]=> string(6) "201303" ["values"]=> int(2287) }
[5]=> array(2) { ["id"]=> string(6) "201302" ["values"]=> int(2251) }
[6]=> array(2) { ["id"]=> string(6) "201301" ["values"]=> int(2474) } }

版主要是条数不对应呢想得到下面的记录怎么办！
最后想得到

array(7) {
[0]=> array(2) { ["id"]=> string(6) "201307"  ["value"]=> int(535) ["values"]=> int(3588) }
[1]=> array(2) { ["id"]=> string(6) "201306"   ["values"]=> int(3177) }
[2]=> array(2) { ["id"]=> string(6) "201305"  ["value"]=> int(758)["values"]=> int(2946) }
[3]=> array(2) { ["id"]=> string(6) "201304"  ["value"]=> int(10) ["values"]=> int(2419) }
[4]=> array(2) { ["id"]=> string(6) "201303" ["value"]=> int(582) ["values"]=> int(2287) }
[5]=> array(2) { ["id"]=> string(6) "201302" ["value"]=> int(390) ["values"]=> int(2251) }
[6]=> array(2) { ["id"]=> string(6) "201301" ["value"]=> int(473) ["values"]=> int(2474) } }

那你就用循环呗

能帮着写个例子么。版主。我写一上午了。新手不会啊！
