Detailed explanation of how to implement PHP reflection mechanism code

Through proxy classClassOneDelegator instead of ClassOne class to implement his method.

The demonstration code is as follows:

<?php 
class ClassOne { 
function callClassOne() { 
print "In Class One"; 
} 
} 
class ClassOneDelegator { 
private $targets; 
function construct() { 
$this->target[] = new ClassOne(); 
} 
function call($name, $args) { 
foreach ($this->target as $obj) { 
$r = new ReflectionClass($obj); 
if ($method = $r->getMethod($name)) { 
if ($method->isPublic() && !$method->isAbstract()) { 
return $method->invoke($obj, $args); 
} 
} 
} 
} 
} 
$obj = new ClassOneDelegator(); 
$obj->callClassOne(); 
?>

Output result:
In Class One
It can be seen that the proxy class ClassOneDelegator is used to replace the ClassOne class to implement his method.
Similarly, the following code can also be run:

<?php 
class ClassOne { 
function callClassOne() { 
print "In Class One"; 
} 
} 
class ClassOneDelegator { 
private $targets; 
function add
Object
($obj) { 
$this->target[] = $obj; 
} 
function call($name, $args) { 
foreach ($this->target as $obj) { 
$r = new ReflectionClass($obj); 
if ($method = $r->getMethod($name)) { 
if ($method->isPublic() && !$method->isAbstract()) { 
return $method->invoke($obj, $args); 
} 
} 
} 
} 
} 
$obj = new ClassOneDelegator(); 
$obj->addObject(new ClassOne()); 
$obj->callClassOne(); 
?>
