如何加入在PHP 2多维数组 [英] how to join two multidimensional arrays in php

问题描述

如何将两个多维数组在PHP？我有两个多维数组A和B.我需要加入A和B，形成一个新的列C如下：

  $ A =阵列（
阵列（A1=大于1，B1=大于2，C1=＆gt;中A），
阵列（A1=大于1，B1=＆GT; 16，C1=＆gt;中Z），
阵列（A1=→3，B1=→8，C1=＆gt;中A））;$ B =阵列（
阵列（A2=大于1，B2=大于2，B2=＆gt;中A），
阵列（A2=大于1，B2=＆GT; 16，B2=＆gt;中G），
阵列（A2=→3，B2=→8，B2=＆gt;中A））;
 

//加入A和B到C型

  $ C =阵列（
阵列（A1=大于1，B1=大于2，C1=＆gt;中A），
阵列（A1=大于1，B1=＆GT; 16，C1=＆gt;中Z），
阵列（A1=→3，B1=→8，C1=＆gt;中A），
阵列（A2=大于1，B2=大于2，B2=＆gt;中A），
阵列（A2=大于1，B2=＆GT; 16，B2=＆gt;中G），
阵列（A2=→3，B2=→8，B2=＆gt;中A））;
 

解决方案

使用 array_merge 函数，就像这样：

  $ C = array_merge（$ A，$ B）;
的print_r（$ C）;
 

当我运行上面的脚本，它会输出：

 阵列（
    [0] =＆GT;阵列（
        [A1] =＆GT; 1
        [B1] =＆GT; 2
        [C1] =＆GT;一个
        ）
        [1] =＆GT;阵列（
            [A1] =＆GT; 1
            [B1] =＆GT; 16
            [C1] =＆GT; Z）
        [2] =＆GT;阵列（
            [A1] =＆GT; 3
            [B1] =＆GT; 8
            [C1] =＆GT;一个
        ）
        [3] =＆GT;阵列（
            [A2] =＆GT; 1
            [B2] =＆GT;一个
        ）
        [4] =＆GT;阵列（
            [A2] =＆GT; 1
            [B2] =＆GT; G
        ）
        [5] =＆GT;阵列（
            [A2] =＆GT; 3
            [B2] =＆GT;一个
        ）
    ）

how to join two multidimensional arrays in php? I have two multidimensional arrays A and B. I need to join A and B to form a new array C as follows

$A = array( 
array("a1"=>1,"b1"=>2,"c1"=>"A"), 
array("a1"=>1,"b1"=>16,"c1"=>"Z"), 
array("a1"=>3,"b1"=>8,"c1"=>"A")); 

$B = array( 
array("a2"=>1,"b2"=>2,"b2"=>"A"), 
array("a2"=>1,"b2"=>16,"b2"=>"G"), 
array("a2"=>3,"b2"=>8,"b2"=>"A")); 

//join A and B to form C

$C=array( 
array("a1"=>1,"b1"=>2,"c1"=>"A"), 
array("a1"=>1,"b1"=>16,"c1"=>"Z"), 
array("a1"=>3,"b1"=>8,"c1"=>"A"),
array("a2"=>1,"b2"=>2,"b2"=>"A"), 
array("a2"=>1,"b2"=>16,"b2"=>"G"), 
array("a2"=>3,"b2"=>8,"b2"=>"A"));

解决方案

Use the array_merge function, like this:

$C = array_merge($A, $B);
print_r($C);

When I run the above script it'll output:

Array ( 
    [0] => Array ( 
        [a1] => 1 
        [b1] => 2 
        [c1] => A 
        ) 
        [1] => Array ( 
            [a1] => 1 
            [b1] => 16 
            [c1] => Z ) 
        [2] => Array ( 
            [a1] => 3 
            [b1] => 8 
            [c1] => A 
        ) 
        [3] => Array ( 
            [a2] => 1 
            [b2] => A
        ) 
        [4] => Array ( 
            [a2] => 1 
            [b2] => G 
        ) 
        [5] => Array ( 
            [a2] => 3 
            [b2] => A 
        )
    )
