無法連接到數據庫與PHP

Question

我怎麼無法連接到數據庫？

Parse error: syntax error, unexpected 'mysql_query' (T_STRING) in C:\xampp2\htdocs\tutorials\abc.php on line 14

<?php 


$user = 'root' ; 
$pass = 'gfcf' ; 

$db = 'testdb' ; 

$con = new mysql('localhost', $user , $pass , $db) or die("UNABLE TO CONNECT"); 

$selected = mysql_select_db($db,con) 


mysql_query(" CREATE TABLE people 
(

firstname varchar(15) 

gender varchar() 


)"); 



?> 

Answer 1

你混合mysql_和mysqli_功能：

$con = new mysqli('localhost', $user , $pass , $db) or die("UNABLE TO CONNECT"); 
$selected = mysqli_select_db($con,$db) 
mysqli_query($con, " CREATE TABLE people 
(
    firstname varchar(15) 
    gender varchar() 
)");
