PHP - accessing global variables in all functions of class
<p>I need to access some variables of an external php file in most of functions of a class. I'm accessing in following way (and it works fine)</p>

<pre><code>class test{

function a(){ 
    global $myglobalvar ;
    ..
    ..
    }

function b(){ 
    global $myglobalvar ;
    ..
    ..
    }

function c(){ 
    global $myglobalvar ;
    ..
    ..
    }

}
</code></pre>

<p>Is there a way that i can access $myglobalvar in all functions of the class without declaring in each function? I did read that it can be done by declaring only once in the constructor of the class, but I dont know how to do it. 
Thanks for any help.</p>
