你好我某处丢失错误，因为它没有定义抛出函数，但在其他测试文件中同样的函数工作正常。
<?php
if(isset($_GET['id']) && isset($_GET['action']) && isset($_GET['friend']))
{
include_once "dbconnect.php";
$act = $_GET['action'];
$idas = $_GET['id'];
$un = $_GET['friend'];
$act = $DBcon->real_escape_string($act);
$un = $DBcon->real_escape_string($un);
$idas = $DBcon->real_escape_string($idas);
$sql = "SELECT * FROM `friends` WHERE `pass`='$un'";
if ($query = $DBcon->query($sql))
{
$row_cnt = mysqli_num_rows($query);
if ($row_cnt != 0)
{
if($act == 0)
{
$sql2 = "DELETE FROM `gyventojai` WHERE `ID`='$idas'";
if ($query2 = $DBcon->query($sql2))
{
echo "User deleted!";
}
else
{
echo "<script>window.parent.location = 'index.php';</script>";
}
}
else if($act == 1)
{
$sql2 = "SELECT * FROM `users` WHERE `ID`='$idas'";
if ($query2 = $DBcon->query($sql2))
{
$uDB = $query2->fetch_array();

感谢您的帮助！代码在id = edituser的地方不起作用，其中createuser函数抛出了未定义createuser的错误。
