Question

我正在尝试从多个SQL表中获取数据（如果它们具有匹配的IMEI）并在html表中显示它们。如果IMEI不匹配，那么我希望它显示＆＃39; - ＆＃39;在那个盒子里。

为此，我有来自表A（导入）的显示数据，然后尝试匹配IMEI。在这样做时，我使用if else来定义条件，主要问题出现在if和else中。在执行代码时，它将执行else部分之后的if部分，它不遵循条件。

例如：

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>
}
}

}

以下是代码。我写了错误＆＃39;在发生错误的代码中

 $sql ="SELECT model,importDate,IMEI1,IMEI2 FROM mainreport ORDER BY id DESC LIMIT $start_from, $limit";
    $result = mysqli_query($con,$sql);
    while ($cgimport = mysqli_fetch_assoc($result)) {
      $cgimport_modelName = $cgimport['model'];
      $cgimport_importDate = $cgimport['importDate'];
      $cgimport_IMEI1 = $cgimport['IMEI1'];
      $cgimport_IMEI2 = $cgimport['IMEI2'];

$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;
                            }


                }
