如何使用PHP将MySQL表导出到Excel？

Question

I am currently developing an App for my school to record Class Cleanliness Results for each class, so I need to convert the results collated in MySQL table into Microsoft Excel using PHP, preferably also able to be opened by a Android OS Phone.

I used the following PHP code:

<?PHP

$mysqli_user = "(user)";
$mysqli_password = "(password)";
$mysqli_host = "(host)";
$mysqli_database = "(database)";


  $filename = "grading_results_" . time() . ".xls";

  header("Content-Disposition: attachment; filename=\"$filename\"");
  header("Content-Type: application/vnd.ms-excel");

$link = mysqli_connect($mysqli_host,$mysqli_user,$mysqli_password,$mysqli_database);
$query = 'SELECT * FROM (table_name)';

$result = mysqli_query($link, $query);

while ($row = mysqli_fetch_row($result)){
 print implode("\t", $row) . "
";
}
mysqli_close($link);
?>

This is how my table looks like in phpMyAdmin:

This is how the Excel file looks like after I used this code to convert.

Why is there no columns and rows? I need the Excel file to be exactly the same formatting and style as the table in phpMyAdmin. Can anyone help edit my code instead of providing me a brand new code?

Thanks in advance for your answers!

Manual

1. Run tour localhost and log in to phpMyAdmin
2. Click on your database then click on the table which you want to get Excel.
3. 

then

1. 
2. then press GO button

With Code

define ("DB_HOST", "localhost");
define ("DB_USER", "root");
define ("DB_PASS","");
define ("DB_NAME","DATABASE_NAME");

$link = mysql_connect(DB_HOST, DB_USER, DB_PASS) or die("Couldn't make connection.");
$db = mysql_select_db(DB_NAME, $link) or die("Couldn't select database");

then

$setCounter = 0;

$setExcelName = "download_excal_file";

$setSql = "YOUR SQL QUERY GOES HERE";

$setRec = mysql_query($setSql);

$setCounter = mysql_num_fields($setRec);

for ($i = 0; $i < $setCounter; $i++) {
    $setMainHeader .= mysql_field_name($setRec, $i)."\t";
}

while($rec = mysql_fetch_row($setRec))  {
  $rowLine = '';
  foreach($rec as $value)       {
    if(!isset($value) || $value == "")  {
      $value = "\t";
    }   else  {
//It escape all the special charactor, quotes from the data.
      $value = strip_tags(str_replace('"', '""', $value));
      $value = '"' . $value . '"' . "\t";
    }
    $rowLine .= $value;
  }
  $setData .= trim($rowLine)."
";
}
  $setData = str_replace("", "", $setData);

if ($setData == "") {
  $setData = "no matching records found";
}

$setCounter = mysql_num_fields($setRec);



//This Header is used to make data download instead of display the data
 header("Content-type: application/octet-stream");

header("Content-Disposition: attachment; filename=".$setExcelName."_Report.xls");
header("Pragma: no-cache");
header("Expires: 0");

//It will print all the Table row as Excel file row with selected column name as header.
echo ucwords($setMainHeader)."
".$setData."
";
