我有這個代碼json代碼[{"title":"Title 1","option":"Option 1"},{"title":"title 2","option":"Option 2"}]我用它來顯示它foreach ($query->getResult() as $row) { foreach (json_decode($row->keywords) as $msg) { echo $msg->title . "<br/>" . $msg->option . "<hr/>"; }}我怎樣才能隨機(jī)顯示這個？

您可以提取關(guān)鍵字?jǐn)?shù)組，然后在顯示前對其進(jìn)行打亂：
foreach ($query->getResult() as $row) {
$keywords = json_decode($row->keywords);
shuffle($keywords);
foreach ($keywords as $msg) {
echo $msg->title . "<br/>" . $msg->option . "<hr/>";
}
}
