使用不同的共享方法和属性扩展PHP类

Question

I have the following three objects which includes the following methods and properties:

$obj1
 - $prop1
 - $prop2
 - $prop3
 - $prop4
 - method1()
 - method2()
 - method3()
 - method4()

$obj2
 - $prop2
 - $prop3
 - $prop4
 - $prop5
 - method2()
 - method3()
 - method4()
 - method5()

$obj3
 - $prop1
 - $prop3
 - $prop4
 - $prop5
 - method1()
 - method3()
 - method4()
 - method5()

All properties and methods of a given name utilize identical script to create them.

One possible script to create these objects is as follows:

class class1 { 
  var $prop1=123, $prop2=array(), $prop3, $prop4;
  public method method1($x) {echo('hello '.$x;}
  public method method2($x) {echo('goodby '.$x;}
  public method method3($x) {echo('hey '.$x;}
  public method method4($x) {echo('seeya '.$x;}
}

class class2 { 
  var $prop2=array(), $prop3, $prop4, $prop5=555,;
  public method method2($x) {echo('goodby '.$x;}
  public method method3($x) {echo('hey '.$x;}
  public method method4($x) {echo('seeya '.$x;}
  public method method5($x) {echo('latter '.$x;}
}

class class3 { 
  var $prop1=123,  $prop3, $prop4, $prop5=555,;
  public method method1($x) {echo('hello '.$x;}
  public method method3($x) {echo('hey '.$x;}
  public method method4($x) {echo('seeya '.$x;}
  public method method5($x) {echo('latter '.$x;}
}

How can I create these three objects without duplicating the script used to create the properties and methods?

Answer 1

Untested and not positive it will work. Also, concerned it will be difficult to maintain.

trait trait_1{
  var $prop1=123;
  public method method1($x) {echo('hello '.$x;}
}
trait trait_2{
  $prop2=array();
  public method method2($x) {echo('goodby '.$x;}
}
trait trait_5{
   $prop5=555;
  public method method5($x) {echo('latter '.$x;}
}

trait trait_3_4{
  var $prop3, $prop4;
  public method method3($x) {echo('hey '.$x;}
  public method method4($x) {echo('seeya '.$x;}
}

class class1 { 
  use trait_1, trait_2,  trait_3_4;
}
class class2 { 
  use trait_2,  trait_3_4, trait_5;
}
class class3 { 
  use trait_1,  trait_3_4, trait_5;
}
