[RESOLVED] calling functions within a function in a class php

[123]

Hi

I have written a two fucntions.

function one ($value) {
	global $value;
   echo $value;

}

function two () {
 global $value;
 one(1);
 $new_value =  $value + 2;
 echo $new_value; 


}

they both work well.

i put these functions in a class and created an instance of the class in another page so that i can access these functions.

When i try to call function two in this way i get an eror message that says;

Fatal error: Call to undefined function one()

any ideas why this is. the problem only seems to occur when i try to use these functions using OOP techniques.

this is the code showing how i called the functions

require_once "func_test.class"; 
$test = new func_test();
$test -> two();

Thanks

The reason is that one(1) invokes the global one() function, but now you have a one() member function of your class. As such, you should call $this->one(1).

Aside from that, you really do not need to make $value global in one(). $value should not be made global in two() either, but could be passed as an argument (or perhaps it should be a member variable, with your example it is not possible to tell).

Thanks for your answer it worked

You're welcome, and I hope you fixed the global declarations by removing them.
