组合数组以在php中形成多维数组

时间:2021-08-16 21:31:41

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:

我知道有很多答案,但我似乎无法做到这一点。我有以下数组和我尝试过的内容:

$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.

但是有了这个我得到错误array_combine()[function.array-combine]:两个参数应该有相同数量的元素。

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:

我知道这是因为$ a的数组值不是键。这就是为什么我来这里看看我是否可以得到一些答案,可以帮助我让它看起来像这样:

array(2) {

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

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


}

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

如果您可以控制创建数组,则应创建它们:

$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:

如果没有,你必须循环它们:

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

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

Here's a new version of array_merge_recursive which will handle integer keys. Let know how it goes.

这是array_merge_recursive的新版本,它将处理整数键。让我们知道它是怎么回事。

$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_merge_recursive2($b, $c, $d));
echo "<pre>";
print_r($e);



function array_merge_recursive2() {
    $args = func_get_args();
    $ret = array();

    foreach ($args as $arr) {
        if(is_array($arr)) {
            foreach ($arr as $key => $val) {
                $ret[$key][] = $val;
            }
        }
    }
    return $ret;
}
