结合阵列形成在PHP多维数组 [英] Combine arrays to form multidimensional array in php

问题描述

我知道有一吨的答案，但我似乎无法得到它的权利。我有以下的阵列和我已经试过：

  $ a =阵列（0 =＆GT;'1421'，1 =＆GT;'2241'）;
$ B =阵列（0 =＆GT;'teststring1'，1 =＆GT;'teststring2'）;
$ C =阵列（0 =＆GT;'teststring3'，1 =＆GT;'teststring4'）;
$ D =阵列（0 =＆GT;'teststring5'，1 =＆GT;'teststring6'）;$ E = array_combine（$ A，阵列（$ B，$ C，$ d）条）;
 

但有了这个我得到的误差 array_combine（）[function.array-结合]：这两个参数应该具有的元素数量相等

我知道这是因为 $ A 的数组值不是关键。这就是为什么我来这里看看，如果我能得到一个答案一定的帮助，可以帮助我使它看起来像这样：

 阵列（2）{  [1421] =＆GT;阵列（[0] =＆GT; teststring1
                 [1] =＆GT; teststring3
                 [2] =＆GT; teststring5
                ）  [2241] =＆GT;阵列（[0] =＆GT; teststring2
                 [1] =＆GT; teststring4
                 [2] =＆GT; teststring6
               ）
}
 

解决方案

如果你有控制创建数组，应创建他们喜欢的：

  $ a =阵列（'1421'，'2241'）;
$ B =阵列（'teststring1'，'teststring3'，'teststring5'）;
$ C =阵列（'teststring2'，'teststring4'，'teststring6'）;$ E = array_combine（$ A，阵列（$ B，$ C））;
 

如果没有，你有遍历它们：

  $结果=阵列（）;
$值=阵列（$ B，$ C，$ D）;的foreach（$ A $作为指数=＆GT; $键）{
    $ T =阵列（）;
    的foreach（$值$值）{
        $ T [] = $价值[$指数]
    }
    $结果[$关键] = $ T;
}
 

DEMO

I know there's a ton of answers but I can't seem to get it right. I have the following arrays and what I've tried:

$a = array ( 0 => '1421' , 1 => '2241' );
$b = array ( 0 => 'teststring1' , 1 => 'teststring2' );
$c = array ( 0 => 'teststring3' , 1 => 'teststring4' );
$d = array ( 0 => 'teststring5' , 1 => 'teststring6' );

$e = array_combine($a, array($b,$c,$d) );

But with this I get the error array_combine() [function.array-combine]: Both parameters should have an equal number of elements.

I know it's because the $a's array values aren't keys. That's why I'm coming here to see if I could get some help with an answer that can help me make it look something like this:

array(2) {

  [1421]=>array( [0] => teststring1
                 [1] => teststring3
                 [2] => teststring5
                )

  [2241]=>array( [0] => teststring2
                 [1] => teststring4
                 [2] => teststring6
               )


}

解决方案

If you have control over creating the arrays, you should create them like:

$a = array ('1421' ,'2241');
$b = array ('teststring1', 'teststring3', 'teststring5');
$c = array ('teststring2', 'teststring4', 'teststring6');

$e = array_combine($a, array($b,$c) );

If not, you have to loop over them:

$result = array();
$values = array($b, $c, $d);

foreach($a as $index => $key) {
    $t = array();
    foreach($values as $value) {
        $t[] = $value[$index];
    }
    $result[$key]  = $t;
}
