Buat kueri penyisipan dari array MySQL dan PHP

Coba ini:

function addUser($usrData) {
   $count = 0;
   $fields = '';

   foreach($usrData as $col => $val) {
      if ($count++ != 0) $fields .= ', ';
      $col = mysql_real_escape_string($col);
      $val = mysql_real_escape_string($val);
      $fields .= "`$col` = $val";
   }

   $query = "INSERT INTO `myTable` SET $fields;";
}
