想要获取一个PHP类的方法,大家可能很自然的想到了get_class_methods(),可手册中并没说明此函数返回的只是public类型的方法。
如果想要获取到包括私有和保护的所有方法,那需要用到PHP中反射类,还是通过例子来说明吧。
<?php
class Foo
{
private function priFunc(){}
protected function proFunc(){}
public function pubFunc(){}
}
function get_class_all_methods($class){
$r = new ReflectionClass($class);
foreach($r->getMethods() as $key=>$methodObj){
if($methodObj->isPrivate())
$methods[$key]['type'] = 'private';
elseif($methodObj->isProtected())
$methods[$key]['type'] = 'protected';
else
$methods[$key]['type'] = 'public';
$methods[$key]['name'] = $methodObj->name;
$methods[$key]['class'] = $methodObj->class;
}
return $methods;
}
$methods = get_class_all_methods('Foo');
var_dump($methods);
结果:
array(3) {
[0]=>
array(3) {
["type"]=>
string(7) "private"
["name"]=>
string(7) "priFunc"
["class"]=>
string(3) "Foo"
}
[1]=>
array(3) {
["type"]=>
string(9) "protected"
["name"]=>
string(7) "proFunc"
["class"]=>
string(3) "Foo"
}
[2]=>
array(3) {
["type"]=>
string(6) "public"
["name"]=>
string(7) "pubFunc"
["class"]=>
string(3) "Foo"
}
}
