Hello

I`ve been wondering how to implement methods in a class. Could someone explain me what means if one does OOP in procedural style?

Here is an example:

class Fld extends Model {

    private $file;
    private $properties = array();

    public function init($file) {   
        $this->file = $file;
        $this->parseFile();
        }

            private function parseFile() {
            // parses the file
                    foreach($this->file as $line)......
                ..................
                $this->properties = $result;
            }

 }

I mean is it a good thing to have methods like these that do operations for the class properties like that. Or should I pass the class property as method parameter... I mean this would cause error if the file property wouldnt be declared.
