PHP sets object properties dynamically

Question

I have a function that needs to read an array and dynamically set the properties of an object.

class A { public $a; public $b; function set($array){ foreach ($array as $key => $value){ if ( property_exists ( $this , $key ) ){ $this->{$key} = $value; } } } } $a = new A(); $val = Array( "a" => "this should be set to property", "b" => "and this also"); $a->set($val); 

Well, obviously this does not work, is there any way to do this?

EDIT

It seems that there is nothing wrong with this code, the question should be closed

You can use Reflection , I think.

 <?php function set(array $array) { $refl = new ReflectionClass($this); foreach ($array as $propertyToSet => $value) { $property = $refl->getProperty($propertyToSet); if ($property instanceof ReflectionProperty) { $property->setValue($this, $value); } } } $a = new A(); $a->set( array( 'a' => 'foo', 'b' => 'bar' ) ); var_dump($a); 

Outputs:

 object(A)[1] public 'a' => string 'foo' (length=3) public 'b' => string 'bar' (length=3) 

Answer 2

You only need to remove the brackets {} and work! → $this->$key = $value;
