使用MySQL的COUNT數多列

Question

我的信息在一個表像這樣：

id name recommender 
1 daniel steve 
2 daniel tony 
3 steve daniel 

和驗證碼：

<h2>Follow/Join Recommendation League Table</h2> 
<br/> 
<?php 

$query = "SELECT name_of_follower, COUNT(name) FROM recommendation_competition_entrants GROUP BY name_of_follower ORDER BY COUNT(name) DESC"; 

$result = mysql_query($query) or die(mysql_error()); 

// Print out result 
while($row = mysql_fetch_array($result)){ 
     echo $row['name_of_follower'] . " has ". $row['COUNT(name)'] . " entries."; 
     echo "<br />"; 
} 

?> 

這個計算所有條目的「名稱」欄，並顯示它看起來像這樣小聯賽積分榜：

daniel - 2 entries 
steve - 1 entry 

我現在需要做的是從兩個名字數名推薦列，所以表格看起來像這樣：

daniel - 3 entries 
steve - 2 entries 
tony - 1 entry 

有沒有簡單的方法來做到這一點？

感謝所有幫助
