Php 附加到关联数组？

我有一个源数组

$A = array(
    0=> array(
        'title'=>'HTML5+CSS3',
        'teacher'=>'jonh',
        'id_post'=>1,/* link to  $post_formation */
        'formation'=>1,
        'date'=>'12/12/2112'
    )
);

和另一个数组：

$post_formation = array(
            0=>array(1,2,3),
            1=>array(3,4,5)
        )

查看

$A

以操作新的result（在本例中

id\u post=1

1=>数组（3,4,5）

因此将包含更多

3个元素

）

---

有人能告诉我怎么做吗？

虽然有点奇怪

$A=array(array("title"=>"HTML5+CSS3","teacher"=>"john","id_post"=>1,"formation"=>1,"date"=>"12/12/2012"));
$post_information=array(0=>array(1,2,3),1=>array(3,4,5));
print_r($A);
if(isset($post_information[$A[0]["id_post"]]))
{
    foreach($post_information[$A[0]["id_post"]] as $idx)
    {
        $cache=$A[0];
        $cache["title"]="(A)".$cache["title"];
        $cache["formation"]=$idx;
        $cache["date"]="--/--/----";
        $A[]=$cache;
    }
}
print_r($A);

结果:

当然，您可以将逻辑封装在函数中，而不是简单地修改源代码

$a

，尽管有点奇怪

$A=array(array("title"=>"HTML5+CSS3","teacher"=>"john","id_post"=>1,"formation"=>1,"date"=>"12/12/2012"));
$post_information=array(0=>array(1,2,3),1=>array(3,4,5));
print_r($A);
if(isset($post_information[$A[0]["id_post"]]))
{
    foreach($post_information[$A[0]["id_post"]] as $idx)
    {
        $cache=$A[0];
        $cache["title"]="(A)".$cache["title"];
        $cache["formation"]=$idx;
        $cache["date"]="--/--/----";
        $A[]=$cache;
    }
}
print_r($A);

当然，您可以将逻辑包装到函数中，而不是以另一种方式简单地修改源代码

$a

  $ArrayPayChannel=array();

 function array_push_assoc($array, $key, $value){
  $array[$key] = $value;
 return $array;
 }

 $ArrayPayChannel = array_push_assoc($ArrayPayChannel, 'Key', 'Value');

---

如果你在数组中有更多的深度，而不是值，你可以放入另一个数组（ArrayPayChannel，'Key，'value'）；而且你有更多你想要的深度

另一种方式，可能更简单

  $ArrayPayChannel=array();

 function array_push_assoc($array, $key, $value){
  $array[$key] = $value;
 return $array;
 }

 $ArrayPayChannel = array_push_assoc($ArrayPayChannel, 'Key', 'Value');

---

如果你在数组中有更多的深度，而不是值，你可以放入另一个数组（ArrayPayChannel，'Key，'value'）；而且你有更多你想要的深度

可以应用更多的元素吗？@BandOfBrothers这取决于源在“更多元素”中的样子，以及你期望的结果是什么。用一个“更多元素”的例子更新你的问题（以及预期的结果），我会看看我是否能做到。如果数组
