The example describes the simple implementation of multi-dimensional array merging and sorting functions in PHP. Share it with everyone for your reference, the details are as follows:

<?php
$record=array(
  &#39;title&#39; =>&#39;这个就是标题，第一个数组&#39;,
  &#39;description&#39; =>&#39;描述内容&#39;,
  &#39;picurl&#39; => &#39;照片的链接&#39;,
  &#39;url&#39; =>&#39;链接&#39;,
  &#39;juli&#39; => 34
);
$record_other=array(
  &#39;title&#39; =>&#39;这个就是标题，第二个数组&#39;,
  &#39;description&#39; =>&#39;描述内容&#39;,
  &#39;picurl&#39; => &#39;照片的链接&#39;,
  &#39;url&#39; =>&#39;链接&#39;,
  &#39;juli&#39; => 14
);
//合并数组
$re=array_merge($record,$record_other);
//升序排列，按照“juli”字段排列
$juli_sort = array();
foreach ($re as $arr2) {
  $juli_sort[] = $arr2[&#39;juli&#39;];
}
array_multisort($juli_sort, SORT_ASC, $re);
var_dump($re);
?>

array(5) {
 ["juli"]=>
 int(14)
 ["url"]=>
 string(4) "链接"
 ["description"]=>
 string(8) "描述内容"
 ["picurl"]=>
 string(10) "照片的链接"
