phpmyadmin和php PDO之间的区别

Question

I'm running a query in Phpmyadmin and also execute the same query with php PDO but results are not equal. What could be wrong ? This is query :

SELECT dim_date_key as date ,dim_jdate_key as jdate, SUM(val_call_counts) as count
FROM `fact_j_service_location_table_ts` 
WHERE `dim_time_stamp` >= '1426451400'
AND `dim_time_stamp` < '1427311800' 
AND dim_service_id  = 2  
GROUP BY dim_date_key  
LIMIT 0,10;

phpmyadmin :

date        jdate       count   
20150316    13931225    5711    
20150317    13931226    6170    
20150318    13931227    7244    
20150319    13931228    7825    
20150320    13931229    6261    
20150321    13940101    4622    
20150322    13940102    4513    
20150323    13940103    4671    

but php returns :

20150316    13931225    6295    
20150317    13931226    6170    
20150318    13931227    7244    
20150319    13931228    14170   
20150320    13931229    6261    
20150321    13940101    4622    
20150322    13940102    16879   
20150323    13940103    4671    

and here is php script :

$sql = "SELECT dim_date_key as date ,dim_jdate_key as jdate, SUM(val_call_counts) as count
    FROM `fact_j_service_location_table_ts` 
    WHERE `dim_time_stamp` >= '1426451400'
    AND `dim_time_stamp` < '1427311800' 
    AND dim_service_id  = 2  
    GROUP BY dim_date_key  
    LIMIT 0,10;";
$db = new PDO($server ,$username, $pass, $opt);
$this_result = $db->prepare($sql);
$this_result->execute();
//$error = $this_result->errorInfo();

$res = $this_result->fetchAll(PDO::FETCH_ASSOC);

I'm not sure but count and date is reservated keyword in MySQL so if you try to escape them, it should work :

AS `date`
AS `count`
