以下代码运行良好。
LibraryTests::TestGetServer();
获取LibraryTest中的函数数组并运行它们:
$methods = get_class_methods('LibraryTests');
foreach ($methods as $method) {
call_user_func('LibraryTests::' . $method . '()' );
}
这引发一个错误:Warning: call_user_func(LibraryTests::TestGetServer()) [function.call-user-func]: First argument is expected to be a valid callback
这是被称为的类
class LibraryTests extends TestUnit {
function TestGetServer() {
TestUnit::AssertEqual(GetServer(), "localhost/");
}
.
.
.
如何修复?
在PHP 5.2.8中工作。
任一(自PHP 5.2.3起):
$methods = get_class_methods('LibraryTests');
foreach ($methods as $method) {
call_user_func('LibraryTests::' . $method);
}
或者(更早):
$methods = get_class_methods('LibraryTests');
foreach ($methods as $method) {
call_user_func(array('LibraryTests', $method));
}
参见call_user_func
文档和回调伪类型文档。
