mysql_query无法在最新的php版本中运行

Question

I am trying to insert data in to MySQL Database, but have been stuck on Data insertion.

I am using Version 3.0.0 of WampServer and PHP 5.6.16, phpMyAdmin 4.5.2.

Everything else are ok, I can UPDATE, DELETE...Except INSERT INTO.

Code

<?php 
$con=@mysql_connect('localhost','root','');
mysql_query('SET NAMES utf8;');
mysql_select_db('mydb',$con);
////////////////////////////////// 
if(isset($_POST['post_files'])) {  
$files = $_POST['files']; 
$title = $_POST['title']; 
////////////////////////////////// 
$query = "INSERT INTO files (`file`, `title`) VALUES ('$files', '$title')";  
if(mysql_query($query))
{ 
echo'OK, Data Inserted.'; 
}
else
{ 
echo 'Sorry! Operation failed.';
}  
}
mysql_close(); 
?>
        

These Bunch of codes were working fine in previous PHP versions.

Answer 1

instead of mysql use mysqli For instance:

• mysql_connect will be replaced by mysqli_connect
• mysql_query will be replaced by mysqli_query($con, $query)
• and so on

Note that, for some functions, you may need to check the parameters carefully: Maybe there are some differences here and there -- but not that many, I'd say: both mysql and mysqli are based on the same library (libmysql ; at least for PHP <= 5.2)

For instance :

with mysql, you have to use the mysql_select_db once connected, to indicate on which database you want to do your queries mysqli, on the other side, allows you to specify that database name as the fourth parameter to mysqli_connect. Still, there is also a mysqli_select_db function that you can use, if you prefer.
