I got an undefined function error.

Here's how my code codes:

class MyClass()
{
 private $var;
  public function SetVarManually($somevar)
   {
    $this->var=$somevar;
   }
  private function IWillUseThisLater($symbol)
   {
    if($symbol=='*') return 1;
    if($symbol=='+') return 0;  
   }
  public function SetVarDifferently()
  {
   $this->var=strval(IWillUseThisLater('*'));
  }
}

$instance=new MyClass;
$instance->SetVarManually('random string'); // this works.
$instance->SetVarDifferently(); // this gives and undefined function error,
                                   //more precisely that IWillUseThisLater is undefined.

$this->var=strval($this->IWillUseThisLater('*'));

I understood my error, but...

Ok, this was just the tip of the iceberg -
I have 2 public functions within my class, and this private one i tried to use wrongly in my example.

In both of the public functions , i call the IWillUseThisLater function as in my example ( without $this-> ) , yet in one of them i do not get the undefined error. Why?

You have to either use $this-> or $self:: to access member functions of a class, unless the functions are nested.

<?php


class Foo {



	

	private function function_two()

	{

		echo "Function Two!";

	}


	public function function_one()

	{

		function function_two() {

			echo "Function One!";

		}

		

		function_two();

		$this->function_two();

	}

}



$foo = new Foo();

$foo->function_one();


?>

Thanks John, just found out that the problem was elsewhere in my code, and yes, i should've used $this->method. So noow it works.
Thanks!
