while while 루프에서 데이터베이스에서 데이터를 가져 오는 루프

Question

여러 SQL 테이블 (일치하는 IMEI가있는 경우)에서 데이터를 가져 와서 html 테이블에 표시하려고합니다. IMEI가 일치하지 않으면 그 상자에 '-'를 표시하고 싶습니다.

표 A (가져 오기)의 데이터를 표시 한 다음 IMEI와 일치 시키려고했습니다. 이렇게하는 동안 나는 조건을 정의하기 위해 다른 것을 사용했고, 주요 문제는 if와 else에서 발생합니다. 코드를 실행하는 동안 else 섹션 다음에 나오는 if 섹션을 실행합니다. else 섹션은 ​​조건을 따르지 않습니다. 예

:

while ($row = mysqli_fetch_assoc($result)){ 
... 
... 
*****************this while shows error 
while($row1 = mysqli_fetch_assoc($result1)){ 
********here after executing if it will execute the else also. it does not follow the condition 
if(import_imei == sales_imei){ 
<td>imei</td> 
}else{ 
<td> - </td> 
} 
} 
... 
************the same condition work here perfectly 
while($row2 = mysqli_fetch_assoc($result2)){ 
if(import_imei == ret_imei){ 
<td>name</td> 
}else{ 
<td> - </td> 
} 
} 

} 

여기 아래 코드이다./: 오류가

$sql ="SELECT model,importDate,IMEI1,IMEI2 FROM mainreport ORDER BY id DESC LIMIT $start_from, $limit";

$sql = "Your First Query.."; 

       $result = mysql_query($sql); 

       $jsonData = array(); 

while ($array = mysql_fetch_assoc($result)) { 

         $follower_id=$array['to_follow_user_id'] 
         $SQL_ONE = "Your Second Query....."; 
          $result_one = mysql_query($SQL_ONE); 
          while ($array_one = mysql_fetch_assoc($result_one)) { 
           $jsonData[] = $array_one; 
          }
