Your code is really great, very useful.

This is a great example to extends the core functions of php OOP features.
<?php
class Multiple_inheritance {
	public $bases = array();

	static function error_die($errno, $errstr, $errfile, $errline) {
		$backtrace = debug_backtrace();
		$detail = $backtrace[4];
		var_dump( $backtrace );
		echo '<b>Fetal Error</b>: '.$errstr.' of class <b>'.$detail['class'].'</b> in <b>'.$detail['file'].'</b> on line <b>'.$detail['line'].'</b><br/>';
		die();
	}

	private function fatal( $text ) {
		set_error_handler( array( 'inheritance', 'error_die' ) );
		trigger_error( $text, E_USER_ERROR );
		restore_error_handler();
	}

	function __call( $name, $args ) {
		if( $this-> bases )
			foreach( $this->bases as $base )
				if( method_exists( $base, $name ) )
					return $base->$name( $args );
		$this->fatal( "Call to undefined method <b>".$name."</b>" );
	}

	function __set( $name, $value ) {
		if( $this->bases ) {
			foreach( $this->bases as $base ) {
				if( property_exists( $base, $name )) {
					$base->$name = $value;
					return;
				}
			}
		}
	}

	function __get( $name ) {
		if( $this->bases ) {
			foreach( $this->bases as $base ) {
				if( property_exists( $base, $name ) ) {
					return $base->$name;
				}
			}
		}
	}

	function __isset( $name ) {
		if( $this->bases ) {
			foreach( $this->bases as $base ) {
				if( property_exists( $base, $name ) ) {
					return isset( $base->$name );
				}
			}
		}
	}

	function __unset( $name ) {
		if( $this->bases ) {
			foreach( $this->bases as $base ) {
				if( property_exists( $base, $name) ) {
					unset( $base->$name );
				}
			}
		}
	}

	function inherits( $name, $args = '' ) {
		return array_unshift( $this->bases, new $name( $args ) );
	}
