php - Returning Multiple Variables with isset() -

-

i have bit of code returns user agent, running through function parse it. code have used returns 1 variable parsing function (there three: 'platform' 'browser' 'version'):

function my_get_user_agent($value) { $browser = parse_user_agent(); return isset($browser['platform']) ? $browser['platform'] : ''; }

while code works return platform of user agent, need append return 3 variables in function. changed first half of code assume correct:

return isset($browser['platform'], $browser['browser'], $browser['version'])? $browser['platform'] : '';

i unsure, however, need return 3 values. suggestions?

you can return entire array:

return $browser;

then access values later:

$browser['platform']; $browser['browser']; $browser['version'];

reading question again, seem want ensure value set. can this:

foreach($browser $value) {     if(isset($value)) {         $data[] = $value;     } } return $data;

now data contain platform, browser, , version.

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
