what's the difference between a method and function?

[MDanz]

is this calling a function or calling a method? what's the difference?

 

$thedatabase->opendb();

 

class Database {

function opendb()
{
$this->connect= mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);

	if(!$this->connect)
	{
	die (mysql_error());

	}
	$db_select = mysql_select_db(DB_NAME, $this->connect);

		if(!$db_select)
		{
		die (mysql_error());

		}

}

}

A method, a function is a function. If it's inside of a class it's a method.

 

The same goes for, a variable is a variable, inside of a class it's a property.

 

On a side note, if that is your database class, have you considered making that opendb function part of your __construct method? Or at least the connection part, the select db part could be it's own function I suppose, if working with multiple databases. Either way is fine

The only differences between functions and methods are that methods reside within a class and have automatic access to variables (properties) defined within that class.
