如何在php中连接两个多维数组
问题描述：
如何在php中连接两个多维数组?我有两个多维数组A和B，需要将A和B连接起来组成一个新的数组C，如下
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"));
//连接A和B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"));
答
使用array_merge函数，像这样:
$C = array_merge($A, $B);
print_r($C);
当我运行上面的脚本时，它会输出:
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
)
)
