致命错误：调用未定义的函数mysq1i_query（）

<?php
$dbhost='localhost';
$dbuser='root';
$dbpass='';
$conn=mysqli_connect($dbhost,$dbuser,$dbpass,"vishal");
$passkey=$_GET['passkey'];
$tblname="data";

$result=mysq1i_query($sql);

    $count=mysqli_num_rows(($result));

        $rows=mysqli_fetch_array($result);
        $name=$rows['name'];
        $emailid=$rows['emailid'];
        $password=$rows['password'];
        $confirm=$rows['confirm'];
        $country=$rows['country'];
        $table2="data1";
        $sql2="INSERT INTO $table2 (name,emailid,password,confirm,country)VALUES  ('$name','$emailid','$password','$confirm','$country')"; $result1=mysqli_query($sql2);

        $sql3="DELETE FROM $tblname WHERE   confirm_code='$passkey'";
        $result2=mysqli_query($sql3);
    }
}
?>

您已在第9行使用

$result=mysq1i_query($sql);

而不是

$result=mysqli_query($sql);

您在这一行中有一个错误：

$result=mysq1i_query($sql);

它在（mysq1i）中不是1

正确的是：

$result=mysqli_query($sql);

当您收到此错误时，未定义函数意味着您没有在代码中定义此函数。
