我想在数组中按键和值,但我不能
$con = mysqli_connect('localhost','root','','wp') or die (mysqli_error('Error:'));
$query = mysqli_query($con,'set names utf8')or die (mysql_error());
$qy = mysqli_query($con,"SELECT ID,post_title FROM wp_posts WHERE post_type='page' AND post_status='publish'")or die (mysql_error());
$arr = array();
while ($row = mysqli_fetch_array($qy)){
$id = "?page_id=".$row['ID'];
$title = $row['post_title'];
$arr[] = $id . "=>" . $title;
array_push($arr, "$id" => "$title");
}
请帮助我..
谢谢^ _ ^

以下是我要做的事情:
$arr = array();
while ($row = mysqli_fetch_assoc($qy)){
$id = $row['ID'];
$arr[$id] = $row['post_title'];
}
然后当你需要打印它们时:
foreach ($arr as $id => $title) {
echo "?page_id={$id}'>{$title}</a>";
// or whatever, depends on how you want to print it
}
不要在阵列中存储不必要的信息(即:?page_id=
)。

你想$arr[$id] = $title
吗?或者你想要这个:
if (!isSet($arr[$id])) {
$arr[$id] = array();
}
$arr[$id][] = $title;
前者会使$arr
包含$id=>$title
。如果存在倍数,后者将使$arr
包含$id=>array($title1,$title2,$title3)
等。
