PHP Class Function Calling

Question

I'm writing my own php class and I have several functions within that class. But am I not allowed to call a function from another function within the same class? Something like this:

class my_Class {
    function one($arg) {
        //does something
    }

    function two($var) {
        $receive = one($var);
    }
}

I tried something like this and it spat out an error saying:

Fatal error: Call to undefined function one()

What am I doing wrong?

If you're coming from Java or C++, note that the use of $this in PHP (aka self in some other languages) is mandatory. — rid

Change it to this:

function two($var) {
      $receive = $this->one($var);
 }

Review the PHP OOP reference: http://www.php.net/manual/en/language.oop5.php
The $this keyword is always required.

Yup, this is exactly what you need to change it too.

It should be

class my_Class {
    function one($arg) {
        // does something
    }
    function two($var) {
        $receive = $this->one($var);
    }
}

@Radu .. i think you should do some test one() would not be global see codepad.viper-7.com/Q85Tp4
