authentication - How does 's login system work?

-
i'm implementing login system similar of stack overflow in 1 of websites. when login stack overflow, creates cookie named usr value. if delete cookie, logged out... so, can think uses sessions, in database, record user sessions. is right? secure? it's other built login/session system. when log in, system generates pseudo-random string identify uniquely - session id, gets sent out via cookie. when return, cookie sent so. so takes value in cookie, looks in session system (could flat files, database, can't tell), finds session represented session id, , loads process request. deleting cookie severs link between , site - on next visit, session cookie (which deleted) isn't sent, so has no way of identifying you, assumes brand new user, , doesn't show of "logged in" portions of site.

php - How to preg_match_all the images which has a http head width>100px and height>80px? -

-
i want match img s that: have 1 of extensions: jpg|png|gif whose src not begin http:// whose width > 100 , height > 100 i started regular expression: preg_match_all("/(href|src)=([\"|']?)([^ \"'>]+\.(jpg|png|gif))\\2/i",$str,$matches); numeric comparisions in regular expressions not simple, , finding width= , height= attributes necessitate way more complex regular expression. see regex tools hence 1 of cases simpler html parser make sense. example querypath use: foreach (qp($html)->find("img, a") $img) { if ($img->attr("width") >= 100 , ...) { echo $img->attr("src"), $img->attr("href"); } } of course using domdocument faster (and more typing..)

types - Null Vs Option in F# -

-
i have problem understanding co-existence of "null" , option in f#. in book have read null value not proper value in f# because way f# eliminates excessive null checking. still allows null-initialized references in f#. in other words, can have null values don't have weapons defend with. why not replace nulls options. because of compatibility issues .net libraries or languages it's still there? if yes can give example shows why can't replaced option? f# avoids use of null when possible, lives in .net eco-system, cannot avoid completely. in perfect world, there no null values, need them. for example, may need call .net method null argument , may need check whether result of .net method call null . the way f# deals is: null used when working types come .net (when have value or argument of type declared in .net, can use null value of type; can test if equals null ) option needed when working f# types, because values of types declared in f# c...
