php - Using arrays by reference -

-

why following code "crashing" in php?

$normal_array       = array(); $array_of_arrayrefs = array( &$normal_array );  end( $array_of_arrayrefs )["one"] = 1; // choking on 1

the expected result final code line appends $normal_array key one having value 1 there no output ever, not prints preceeding code. in real context of scenario use end() function append last array reference.

this doesn't crash, contains syntax error:

end( $array_of_arrayrefs )["one"] = 1;

unfortunately, cannot treat function return values arrays in php. have assign value explicitly. unfortunately, doesn't work here because end makes copy of returned value.

unit testing - How to mock PreferenceManager in Android? -

-
i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
