 $arrempty =array();

 for($i=0;$i<count($courseinfo['olinelist']);$i++){
     if(!in_array($courseinfo['olinelist'][$i]['onday'],$arrempty)){
         echo "<pre>";
         print_r($courseinfo['olinelist']);
     }
 }

查看日期，在显示每个循环时，会话应为空白

我想要做的是从数组中删除重复的元素值并将密钥保持为空白。我曾尝试使用array_unique（$ myarray），但它似乎无法正常工作。请帮忙!!!

试试这个：

 $arrempty =array();

 for($i=0;$i<count($courseinfo['olinelist']);$i++){
     if(!in_array($courseinfo['olinelist'][$i]['onday'],$arrempty['onday'])){
         $arrempty[] = $courseinfo['olinelist'][$i];
         echo "<pre>";
         print_r($courseinfo['olinelist'][$i]);
     }
 }
