php classes well known error

[valtido]

hi i got this class

 

class foo{

      function myFunc(){

 

      }

 

}

 

 

$var = new foo();

 

function random(){

    echo $var->myFunc();

 

}

 

 

when i do that it shows me the following error

Fatal error: Call to a member function users() on a non-object

 

how ever if i try to echo it outside the random function it works fine.

 

anyone got any ideas how make this work please.

 

thnx

You need to either pass $var as a parameter, or call it as global:

$var = new foo();

function random($var){
    echo $var->myFunc();
}
random($var);

 

or

 

$var = new foo();

function random(){
    global $var;
    echo $var->myFunc();
}
random();

i tried to global it within the random function but it said "you cannot redeclare $var"

 

and the first one well... i have done that already because i had to call the random func in order for it to display the error.

 

but thnx for ur post m8 much appriciated
