An example of using reflection to avoid typing.

AutoConstructor

<?php




 trait Auto{
     
     
     function auto($args) {

         $reflectionClass = new ReflectionClass($this);

         $reflectionMethod = $reflectionClass->getMethod ('__construct');

         $parameters = $reflectionMethod->getParameters();
         
         $count = 0;
         
         foreach($parameters as $parameter) {
             
             $paramName = $parameter->getName();
                 
             if ($reflectionClass->hasProperty($paramName) == true) {
                $this->{$paramName} = $args[$count];  
             }

             $count++;
         }
         
     }
     
 }



class TestClass {
    
    use Auto;
    
    private $foo;
    
    private $bar;
    
    function __construct($foo, $bar) {
        
        $args = func_get_args();

        $this->auto($args);
    }
 
    function getFoo() {
        return $this->foo;
