to expand even further on this, your class variables are not being utilized.
These guys:
PHP Code:
private $dbn;
private $user;
private $pass;
The variables inside of the function ($dbn, $user, and $pass) are all local to the function, and will no longer be usable outside of the function. You need to assign them to use them outside of it.
Also, constructers are very useful as it will execute as soon as the object is initialized. I ahve the constructor called below to call the two functions. The constructor can be either called __constructor or the exact name of the class in this case: db_connect
PHP Code:
<?php
class db_connect
{
private $dbn;
private $user;
private $pass;
public function db_connect()
{
$this->specs('localhost', 'username', 'password');
$this->showConnectionDetails();
}
public function specs($dbn, $user, $pass)
{
$this->dbn = $dbn;
$this->user = $user;
$this->pass = $pass;
$dbtestcon = mysql_connect($dbn, $user, $pass);
if (!$dbtestcon)
{
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
}
// Now this function will work
function showConnectionDetails()
{
echo 'We connected on ' . $this->dbn . ' with username: ' . $this->user . ' and password ' . $this->password';
}
}
?>
PHP Code:
$database_connection = new db_connect();
// Will output:
// 'connected succesfully'
// We connected on 'localhost' with username: 'username' and password 'password'
