Question

这是我的两个阵列：

$test = array(
    "0" => array(
        "mem_id" => "299", 
        "profilenam" => "Guys&Dolls", 
        "photo_b_thumb" => "photos/935a89f58ef2f3c7aaaf294cb1461d64bth.jpeg"
    ), 
    "1" => array(
        "mem_id" => "344", 
        "profilenam" => "Dmitry", 
        "photo_b_thumb" => "no")
    );

$distance = array(
    "0" => "0", 
    "1" => "3.362", 
    "2" => "0.23"
);

我希望将它们组合为：

Array
(
    [0] => Array
        (
            [mem_id] => 299
            [profilenam] => Guys&Dolls
            [photo_b_thumb] => photos/935a89f58ef2f3c7aaaf294cb1461d64bth.jpeg
            [distance] => 3.362
         )

    [1] => Array
        (
            [mem_id] => 344
            [profilenam] => Dmitry
            [photo_b_thumb] => no
            [distance] => 0.23
        )

)

我尝试了下面的代码，但它不起作用：

foreach ($test as $key => $value) {
    $merged = array_merge((array) $value, $distance);
}
print_r($merged);

Answer 1

<?php

    foreach($test as $index=>$array)
    {
         $test[$index]['distance'] = $distance[$index]
    }

    print_r($test);
?>

Answer 2

$test = array("0" => array("mem_id" => "299", "profilenam" => "Guys&Dolls", "photo_b_thumb" => "photos/935a89f58ef2f3c7aaaf294cb1461d64bth.jpeg"
    ), "1" => array("mem_id" => "344", "profilenam" => "Dmitry", "photo_b_thumb" => "no"));

$distance = array("0" => "0", "1" => "3.362", "2" => "0.23");

foreach( $test as $id => $data ) {
    $test[$id]['distance'] = $distance[$id];
}

这样的事情应该有效！

Answer 3

foreach ($test as $key => &$value) {
  $value["distance"] = $distance[$key];
}

Answer 4

我认为array_merge_recursive可以满足您的需求。

编辑：事实并非如此。 :)然而，在array_map_recursive手册页中发布的它的衍生物似乎确实如此，请参阅this codepad。我有兴趣知道哪个比大数据集更快。

Answer 5

foreach ($test as &$value)
{
   $value['distance'] = array_shift($distance);
}

如何合并这两个数组？
