[PHP]获取静态方法调用者的类名和运用call_user_func_array代入对象作用域

一、获取静态方法调用者的类名

方法一:
class foo {
static public function test() {
var_dump(get_called_class());
}
} class bar extends foo {
} foo::test();
bar::test(); 输出: string(3) "foo"
string(3) "bar" 方法二:
class Bar {
public static function test() {
var_dump(static::class);
}
} class Foo extends Bar { } Foo::test();
Bar::test(); Output: string(3) "Foo"
string(3) "Bar"

二、运用call_user_func_array代入对象作用域

<?php
function foobar ( $arg , $arg2 ) {
echo __FUNCTION__ , " got $arg and $arg2 \n" ;
}
class foo {
function bar ( $arg , $arg2 ) {
echo __METHOD__ , " got $arg and $arg2 \n" ;
}
} // Call the foobar() function with 2 arguments
call_user_func_array ( "foobar" , array( "one" , "two" )); // Call the $foo->bar() method with 2 arguments
$foo = new foo ;
call_user_func_array (array( $foo , "bar" ), array( "three" , "four" ));
?>
