Using "includes" in an OO PHP Class
I have a class that inserts information into a MySQL database. I have the connection variables set as fields at the top of the class. When I run the class it works perfectly.
I would like to simply store the class fields in a separate file (not a class but just the fields s开发者_如何学编程aved in a file) and include it inside my class. when I do this though, it doesn't work. Why is this?

Here's the Code:
class RegChecker{
//set database connection fields
public $hostname_db_conn = "localhost";
public $database_db_conn = "thesis_db";
public $username_db_conn = "root";
public $password_db_conn = "";
......
}
I simply just want to take those four fields and store them in a simple php file and include it in place of them in the actual class e.g.
class RegChecker{
//set database connection fields
include ("db_connection_fields");
......
}
This doesn't work however.
You can't use include statement inside class, only inside methods. You can do something like this
class RegChecker {
function __construct() {
$this->db_params = include 'db.conf.php';
}
}
inside db.conf.php
return array(
'host' => 'localhost',
'user' => 'root',
'pass' => '',
'db' => 'thesis_db'
);
BTW, RegChecker is an awful name for class establishing connection to a database. Common practice to make separate Db class and pass this instance everywhere it needed.
You are inserting a class into a class. This does not work in PHP.
I'm trying to figure out if you can inject code into a class in PHP this way.
