mysqli - Why query not working in from my php -


i have query, , have database. when query in dbforge(mysql) got result. when php, got nothing. can't understand why? if write query simple "select * table id = 1", working. below code:

<?php             $conn = mysqli_connect("localhost", "username", "pass", "db");             ini_set('max_execution_time', 300);                  if (mysqli_connect_errno())              {                 printf("connect failed: %s\n", mysqli_connect_error());                 exit();              }             mysqli_query($conn, "set character set utf8 ");              $result = mysqli_query($conn, "select distinct level_two reportls._report_sales_report level_one = 'Музыка'");             if($result == false)             {                 die('invalid query: '.mysqli_error($conn));                 echo "error";             }                            while ($data = mysqli_fetch_row($result))              {             if(!empty($data[0]))               $sendback = $sendback."<option value=\"$data[0]\">$data[0]</option>";             }             echo ($sendback);             $sendback = '';             mysqli_free_result($result); ?>

this code return nothing. if paste query dbforge, returns rows. me, or write hits? wrote not correct?

you can try when set charset utf8

/* change character set utf8 */ if (!$mysqli->set_charset("utf8")) {     printf("error loading character set utf8: %s\n", $mysqli->error); } else {     printf("current character set: %s\n", $mysqli->character_set_name()); }

related this.
