mysqli_fetch_array錯誤未定義的偏移量：1

Question

我有5個sp_id，$ count也給了5個。但是當我通過mysqli_fetch_array檢查大小時，它給了我2號尺寸，只打印1並給出錯誤未定義偏移量：1進一步。獲取ids的值，我的意思是通過for循環打印id。

 $selectId="Select sp_id from stitchedproduct"; 
$selectIdR = mysqli_query($connection,$selectId) or die(mysqli_error($connection)); 
$count = mysqli_num_rows($selectIdR); 
$fetchedResult= mysqli_fetch_array($selectIdR); 

for ($i=0;$i < $count; $i++) { 
print $fetchedResult[$i]; 
    } 

Answer 1

更換

$fetchedResult= mysqli_fetch_array($selectIdR); 

for ($i=0;$i < $count; $i++) { 
    print $fetchedResult[$i]; 
} 

與

while($fetchedResult= mysqli_fetch_array($selectIdR)) { 
    print $fetchedResult['sp_id']; 
}
