我已经尝试了一天了，但无法让它发挥作用。
我从一个分页的源（比如本例中的3个页面）获得信息。所以我有3个数组要合并：
Array
(
[status] => Active
[nrEntries] => 6
[entries] => Array
(
[0] => Array
(
[sgname] => Merc
[timeentered] => 2016-02-08 04:30:00
)
[1] => Array
(
[sgname] => bystander
[timeentered] => 2016-03-17 20:55:00
)
)
)
Array
(
[status] => Active
[nrEntries] => 6
[entries] => Array
(
[0] => Array
(
[sgname] => Elvis
[timeentered] => 2016-03-08 04:30:00
)
[1] => Array
(
[sgname] => marcAR
[timeentered] => 2016-03-07 20:55:00
)
)
)
Array
(
[status] => Active
[nrEntries] => 6
[entries] => Array
(
[0] => Array
(
[sgname] => Killer
[timeentered] => 2016-03-09 05:30:00
)
[1] => Array
(
[sgname] => MyName
[timeentered] => 2016-03-05 21:45:00
)
)
)
我想要的结果是将它们合并到一个数组中，然后作为结果返回。
Array
(
[status] => Active
[nrEntries] => 6
[entries] => Array
(
[0] => Array
(
[sgname] => Merc
[timeentered] => 2016-02-08 04:30:00
)
[1] => Array
(
[sgname] => bystander
[timeentered] => 2016-03-17 20:55:00
)
[2] => Array
(
[sgname] => Elvis
[timeentered] => 2016-03-08 04:30:00
)
[3] => Array
(
[sgname] => marcAR
[timeentered] => 2016-03-07 20:55:00
)
[4] => Array
(
[sgname] => Killer
[timeentered] => 2016-03-09 05:30:00
)
[5] => Array
(
[sgname] => MyName
[timeentered] => 2016-03-05 21:45:00
)
)
)
我遇到的问题是，使用array_merge无法工作，因为记录的索引号相同。
我尝试了以下方法，但也不起作用。
<?PHP
// add child array to the end of $result
for ($i=0 ; $i<2; $i++) {
$result['entries'][($page*2)+$i][] = $resultChild['entries'][$i];
}
?>
$a1['entries'] = array_merge_recursive($a1['entries'], $a2['entries'], $a3['entries']);
试试这个：
$array1 = array(
'status' => 'Active',
'nrEntries' => 6,
'entries' => array(
array(
'sgname' => 'Merc',
'timeentered' => '2016-02-08 04:30:00'
),
array(
'sgname' => 'bystander',
'timeentered' => '2016-03-17 20:55:00'
)
)
);
$array2 = array(
'status' => 'Active',
'nrEntries' => 6,
'entries' => array(
array(
'sgname' => 'Elvis',
'timeentered' => '2016-03-08 04:30:00'
),
array(
'sgname' => 'marcAR',
'timeentered' => '2016-03-07 20:55:00'
)
)
);
$result = array_merge_recursive($array1, $array2);
$result['status'] = array_unique($result['status'])[0];
$result['nrEntries'] = array_unique($result['nrEntries'])[0];
echo "<pre>";
print_r($result);
echo "</pre>";
这给出了以下内容：
Array
(
[status] => Active
[nrEntries] => 6
[entries] => Array
(
[0] => Array
(
[sgname] => Merc
[timeentered] => 2016-02-08 04:30:00
)
[1] => Array
(
[sgname] => bystander
[timeentered] => 2016-03-17 20:55:00
)
[2] => Array
(
[sgname] => Elvis
[timeentered] => 2016-03-08 04:30:00
)
[3] => Array
(
[sgname] => marcAR
[timeentered] => 2016-03-07 20:55:00
)
)
)
希望这能有所帮助。
array_merge()不是递归的，因此它将替换整个条目数组。有一个名为array_merge_recursive()的函数，但在您的情况下也不起作用，因为它将在status和nrEntries下创建包含所有数组值的数组。
您需要做的是合并"大"页面数组，然后分别合并条目。这可能看起来像这样：
// Keep all pages in an array
$pages = [$pageOne, $pageTwo, $pageThree];
// Merge the page arrays
$result = array_merge(...$pages);
// Clear entries as they only contain the data from the last page
$result['entries'] = [];
// Merge entries with the entries of each page separately
foreach ($pages as $page) {
$result['entries'] = array_merge($result['entries'], $page['entries']);
}
这是我能想到的最简单的例子。我希望它能帮助你理解正在发生的事情，这样你就可以重构它来满足你的需求。
只要条目数组具有从0开始的数字键，array_merge就会附加这些值，而不是替换它们。
