Include file problem

[dd2fru]

I have around 60 php pages application.I want to use php class, but i'm worried about the overhead it is gonna cost me as i have to include this class in all of my pages.

e.g

// In class_xyz.php
class xyz{

function my_exmple_func( ){

 return abc;

}

}

//In page1.php

include "class_xyz.php";

$a= new xyz()

$b=$a->my_example_func();

is there any other way to aviod include files to all of the 60 php pages?what is the overhead of include files?

It doesn't really matter how many pages it is: the class is only loaded once per script run anyway; and afterwards everything's cleaned up ready for the next run. So as far as including the class goes, it makes no difference if it's sixty scripts being run once each, or one script being run sixty times (and of course, those runs could be for sixty different users or just one).
