从mysql中获取选项值

I new to php and mysql.

I wrote the function below:

function catOption() {
$maincatfunc_query = mysql_query("SELECT * FROM mainCats ORDER BY id ") or die(mysql_error());
$funcCat = array();
while ($mainCatFunc = mysql_fetch_array($maincatfunc_query)) {
    for ($i = 0; $i < count($maincatfunc_query); $i++) {



        $funcCat[$i] = '<option value="'.$maincatfunc_sorgu['mainCatID'].'">' . $maincatfunc_sorgu['name'] . '</option>';
    }
}
for ($i = 0; $i < count($maincatfunc_query); $i++) {

    return $funcCat[$i];
  }
}

I want to fetch "all" value from mysql database and fill it in a dropdown. So i wrote a function like this. But it does not work.

And i don't think count() function doesn't really work in this conditions. How can i get the max count of mysql array ?.

or besides can i do this without using a function ?. I've googled it for a long time but i can't find any usefull info.

Thanks !

    You should use like below: [returns array]

    function catOption()
    {
      $query = mysql_query("SELECT * FROM mainCats ORDER BY id ") or die(mysql_error());
      $arrCat = array();
      while ($row = mysql_fetch_array($query)) {
        $arrCat[] = '<option value="'. $row['mainCatID'].'">'. $row['name'].'</option>';
      }
      return $arrCat;
    }
    

    Or this one [returns string]

    function catOption()
    {
      $query = mysql_query("SELECT * FROM mainCats ORDER BY id ") or die(mysql_error());
      $arrCat = "";
      while ($row = mysql_fetch_array($query)) {
        $arrCat .= '<option value="'. $row['mainCatID'].'">'. $row['name'].'</option>';
      }
      return $arrCat;
    }
