how to provide information from a mysql database on a website using php
Question
I have a problem with providing infromation from a mysql database through php. I am working with brackets and always when I try to connect with my database (opening my connection, giving information about my server, port and the name of the dtabase -> shown in the code below) nothing happens. I can not administrate my database with phpmyadmin I know that would be easy. I also have xamp and a apache server working, but then I would have to use phpmyadmin to connect.
But is there a way to connect the database (created with mysql workbench running on localhost 127.0.0.1 and port 3306) only like that with my php file. Or is the problem that I have a mistake in my code?
Code:
File one: db_connection.php
<!DOCTYPE html>
<html>
<header>
<center> <h1>My New Website </h1> </center>
</header>
<body>
<?php
//die echo Funktion, ist dafür da, dass etwas in den Browser ausgegeben wird (same as Syso)
//echo "Hello World!";
function OpenConnection()
{
$dbhost = "localhost";
$dbuser = "root";
$dbpassword = "";
$dbname = "dml_final";
$connection = new mysqli_connect($dbhost, $dbuser, $dbpassword, $dbname)
or die ("Connection failed: %s\n". $connection -> error);
return connection;
}
function CloseConnection()
{
$connection -> close();
}
?>
</body>
</html>
File two: index.php
<?php requires 'db_connection.php'; ?>
<!DOCTYPE html>
<html>
<header>
<center> <h1>My New Website </h1> </center>
</header>
<body>
<?php
$connection = openConnection();
echo "Connection successfully!";
CloseConnection($connection);
?>
</body>
</html>

If you want to use your current way, change function to public function so that it is globally available across your website, I recommend the following method instead:
$dbhost = "localhost";
$dbuser = "root";
$dbpassword = "";
$dbname = "dml_final";
$connection = mysqli_connect($dbhost, $dbuser, $dbpassword, $dbname);
if(!$connection) {
die("Connection failed:".mysqli_connect_error());
}
And you include this in all of your PHP files. To close the connection, simply run a mysqli_close($connection); . I don't know about you, but I find this way more simple.
