PHP: preg_match_all - Couldn't write a working RegEx -

-

i have example string \try tester234 want find word (partially digits) (regex => (\w|\d)) after \try. var_dump($match) outputs that:

array   0 =>      array       empty   1 =>      array       empty 
preg_match_all('/^\\try ((\d|\w)*)/i', "\try tester", $match);

what doing wrong?

you need 4 backslashes insert literal 1 in regular expression:

preg_match_all('/^\\\\block ((\d|\w)*)/i', "\block tester", $match);

which maybe better written this:

preg_match_all('/^\\\\block (\w+)/i', "\block tester", $match);

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...
