The question is, is a class equal to object-oriented or procedural

objekt.php

<?php

class object_class {
    
	/**
	 * holds some data
	 * @var object
	 */
	public static $var = 0;;


        /**
	 * Class Constructor
	 *
	 * @author rreimann
	 * @return void
	 */
	public function __construct() {
		
            #Do some on class initialization
	
	}


        /**
	 * a initail function
	 *
	 * @author rreimann
	 * @return int
	 */
	public function init( $param ) {
		
            self::$var = $param;
        
            #do some
        
            return self::$var;
	
	}
	
}

$object = new object_class();

echo $object->init( 1 );

procedual.php

<?php

class procedural_class {


        /**
	 * Class Constructor
	 *
	 * @author rreimann
	 * @return void
	 */
	public function __construct( $param ) {
		
	    if( $param = 1 ){
            
                #doanything
            
            }elseif( $param = 2 ){
            
                #doanything

                #doanything
            
            }elseif( $param = 5 ){
