解析错误:语法错误，第 4 行 /home/csgoxdne/public_html/set.php 中意外的“mysq

我收到此错误：解析错误：语法错误，第 4 行/home/csgoxdne/public_html/set.php 中意外的"mysqli_set_charset"（T_STRING

这是代码：

<?php
$mysqli = new mysqli("localhost:3306", "csgoxdnet", "secretpassword");
  if ($mysqli->error) print ("Error connecting! Message: ".$mysqli->error) 
mysqli_set_charset($mysqli, 'utf8');
function fetchinfo($rowname,$tablename,$finder,$findervalue)
  {($finder == "1");
      $query ="SELECT * FROM $tablename WHERE rowname = '$rowname'";
      $result = mysqli_query($mysqli, $query); 
}
else
    {
         $query = "SELECT * FROM $tablename WHERE `$finder`='$findervalue'"
         if (!$query)   {die    ('Invalid query: '.$mysqli->error)}
         $result = mysqli_query($mysqli, $query);
 }
 return $result;

老实说，我无法修复错误。提前感谢您的帮助。
