Example #1 ReflectionClass::isInstantiable() example

<?php
class { }

interface 
iface {
    function 
f1();
}

class 
ifaceImpl implements iface {
    function 
f1() {}
}

abstract class 
abstractClass {
    function 
f1() { }
    abstract function 
f2();
}

class 
extends abstractClass {
    function 
f2() { }
}

class 
privateConstructor {
    private function 
__construct() { }
}

$classes = array(
    
"C",
    
"iface",
    
"ifaceImpl",
    
"abstractClass",
    
"D",
    
"privateConstructor",
);

foreach(
$classes  as $class ) {
    
$reflectionClass = new ReflectionClass($class);
    echo 
"Is $class instantiable?  ";
    
var_dump($reflectionClass->IsInstantiable()); 
}

?>

The above example will output:

 Is C instantiable? bool(true) Is iface instantiable? bool(false) Is ifaceImpl instantiable? bool(true) Is abstractClass instantiable? bool(false) Is D instantiable? bool(true) Is privateConstructor instantiable? bool(false)
