如何在php中加入两个多维数组?我有两个多维数组A和B.我需要连接A和B以形成一个新的数组C,如下所示

$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

//加入A和B以形成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"));

Use the array_merge function, like this:

使用array_merge函数,如下所示:

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

When I run the above script it'll output:

当我运行上面的脚本时它会输出:

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 
        )
    )

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

should do the trick (docs).

应该做的伎俩(docs)。

Did you try some PHP array functions? I think some of these work: array_merge_recursive(), array_merge().

你尝试过一些PHP数组函数吗?我认为其中一些工作:array_merge_recursive(),array_merge()。

$array1 = array("farbe" => "rot", 2, 4);
$array2 = array("a", "b", "farbe" => "grün", "form" => "trapezoid", 4);
$result = array_merge($array1, $array2);
print_r($result);

#4

you can also do this as

你也可以这样做

foreach($B as $key => $value){
    $C[$key] = array_merge($A[$key], $B[$key]);
}

Hi I have faced same situation where i had to show duplicate events in calendar

嗨,我遇到了同样的情况,我不得不在日历中显示重复的事件

So i used this solution:-

所以我用这个解决方案: -

 public function array_interlace() {
    $args = func_get_args();
    $total = count($args);

    if($total < 2) {
        return FALSE;
    }

    $i = 0;
    $j = 0;
    $arr = array();

    foreach($args as $arg) {
        foreach($arg as $v) {
            $arr[$j] = $v;
            $j += $total;
        }

        $i++;
        $j = $i;
    }

    ksort($arr);
    return array_values($arr);
}

Required output of array

数组所需的输出

$a = array('a', 'b', 'c', 'd');
$b = array('a','e', 'f', 'g');
$c = array('h', 'i', 'j');
$d = array('k', 'l', 'm', 'n', 'o');

print_r(array_interlace($a, $b, $c, $d));
Array
(
[0] => a
[1] => a
[2] => h
[3] => k
[4] => b
[5] => e
[6] => i
[7] => l
[8] => c
[9] => f
[10] => j
[11] => m
[12] => d
[13] => g
[14] => n
[15] => o
)
