How can i use class from all over site?

[Crofty]

Basically i have a class which is declared within the index page but say i go to a new page and i use a meta refresh the class wont be accessiable for some reason, i try to print/echo the information but nothing is displayed. The infomration is getting stored in the class because if i print/echo from the index it will display the information. I was thinking maybe i would have to store the class in a session but not 100% sure how i would go about retrieving the information, So does anyone have any idea?

	if($this->mysqlConnection =connect())
	{

		//check weather user has sessions already
		return true;
	}else{
		echo 'Error Connecting To Database';
		return false;
	}

}

function Login ($email = "",$password = ""){
	if($this->mysqlConnected)
	{

Why don't you just put the class in a file and then include it on what ever pages you want ???

[PFMaBiSmAd]

Web servers and web pages are stateless. When the code on any page reaches the end of that page, all resources used in that code are destroyed.

 

To make any data carry between pages, you would need to store it in a session. You can either serialize your object data and save it in a session variable or you can directly create a class in a session and as long as the class definition is present when the session_start() is executed, the class data will be available on another page.
