Anonymous (class)es
Anonymous classes
Support for anonymous classes was added in PHP 7. Anonymous classes are useful when simple, one-off objects need to be created.
<?php
// Pre PHP 7 code
class Logger
{
public function log($msg)
{
echo $msg;
}
}
$util->setLogger(new Logger());
// PHP 7+ code
$util->setLogger(new class {
public function log($msg)
{
echo $msg;
}
}); They can pass arguments through to their constructors, extend other classes, implement interfaces, and use traits just like a normal class can:
<?php
class SomeClass {}
interface SomeInterface {}
trait SomeTrait {}
var_dump(new class(10) extends SomeClass implements SomeInterface {
private $num;
