Mysql检查最后一个变量是否相同 - mysql check if last variable is the same

mysql check if last variable is the same

我试图回显$rinse变量，但一无所获但我找到了一个$rang['email']，任何线索都会很好我也试过做$rinse == $rang['email'];

while($rang = mysql_fetch_assoc($results))
{
    if ($rang['email'] = $rinse){
        echo $rang['email'];
    }
    $rinse = $rang['email'];
}

my code updated:

echo $rinse; 
    if ($rang['email'] == $rinse){
         echo $rang['email']; 
        }
 $rinse = $rang['email']

在if语句中需要两个=。

if ($rang['email'] == $rinse){

您应该添加double ==。这是比较，单个=表示设置为

while($rang = mysql_fetch_assoc($results))
{
    if ($rang['email'] == $rinse){
        echo $rang['email'];
    }
    $rinse = $rang['email'];
}
