mysql_fetch_object：獲取一個和對象，下一個？

Question

我有一個項目列表，這些是路線的點。這就是我想實現：

<ul> 
     <li>Point A - Point B</li> 
     <li>Point B - Point C</li> 
     <li>Point C - Point D</li> 
     <li>Point D - Point E</li> 
    </ul> 

不過話又說回來，我只知道如何讓他們中的一個，以便一旦這樣做：

while($row=mysql_fetch_object($res)){ 
    echo'<li>'.$row->title.'</li>'; 
    } 

我能在同一迴路中的兩個點？我應該如何循環以獲得一個點和下一個點？ （我的SQL查詢給了我命令，像這樣的點：A點，B，點C，點d，e點）

Answer 1

//Note that this requires at least two rows to work. 
//Check with mysql_num_rows before running this if you are unsure. 
$first = mysql_fetch_object($res); 
$second = mysql_fetch_object($res); 

do { 

    //do something with the two rows here 
    //in your case: 
    echo'<li>'. $first->title .' - '. $second->title .'</li>'; 

    //Move the second row to be the first 
    $first = $second; 
} while($second = mysql_fetch_object($res)); 

Answer 2

while($row=mysql_fetch_object($res)){ 
    $myresult[] = $row->title; 
    } 

foreach($myresult as $key=>$value){ 

    echo $value->title . (isset($myresult[$key+1]) ? ('-'. $myresult[$key+1]->title): ''); 

}
