I am basically a asp guy. Trying convert this little piece of php code below to asp.net. What it does is read the content from a page. I dont understand the last line in red color, what it does. Can somebody please explain. $request = 'http://www.google.com'; $output = unserialize(file_get_contents($request)); $incoming_links=$output[ResultSet][totalResultsAvailable];
The square brackets mean it's an array. Since you have 2 sets, it's a 2-dimensional array so the value for $incoming_links is being set to whatever the equivalent is in the output array in the position of the 2 values ResultSet and totalResultsAvailable.
I guess you replaced the real URL by the Google one for the sake of the POST because that kind of processing does not make any sense for Google home page !
you should use: $output['ResultSet']['totalResultsAvailable']; PHP: though, as php will throw a NOTICE error when parsing your code (if error_reporting is set to E_ALL). It will either display the error, or store it in the error.log file of you server. The reason why it will throw this error is because php will look for a constant named ResultSet and totalResultsAvailable, and won't be able to find it Anyway: Cesay allready gave the solution to your problem
yes i replaced the url with google, i just put an example there. The value hold by the variable $output is as follows: a:1:{s:9:"ResultSet";a:4:{s:21:"totalResultsAvailable";s:3:"555";s:19:"firstResultPosition";s:1:"1";s:20:"totalResultsReturned";s:2:"50";s:6:"Result";a:50:{i:0;a:3:{s:5:"Title";s:11:"Crazy Quilt";s:3:"Url";s:32:"http://aldebaran14.blogspot.com/";s:8:"ClickUrl";s:32:"http://aldebaran14.blogspot.com/";}i:1;a:3:{s:5:"Title";s:15:"NepalChurch.com";s:3:"Url";s:50:"http://www.nepalchurch.com/general/usefullinks.php";s:8:"ClickUrl";s:50:"http://www.nepalchurch.com/general/usefullinks.php";}i:2;a:3:{s:5:"Title";s:17:"ADVERTISE ME FREE";s:3:"Url";s:31:"http://www.advertisemefree.com/";s:8:"ClickUrl";s:31:"http://www.advertisemefree.com/";}i:3;a:3:{s:5:"Title";s:41:"Stories Tagged 'free tool' " Netscape.com";s:3:"Url";s:37:"http://www.netscape.com/tag/free+tool";s:8:"ClickUrl";s:37:"http://www.netscape.com/tag/free+tool";}i:4;a:3:{s:5:"Title";s:36:"LINK EXCHANGE BY WWW.SILOMSTREET.COM";s:3:"Url";s:40:"http://www.silomstreet.com/link-exchange";s:8:"ClickUrl";s:40:"http://www.silomstreet.com/link-exchange";}i:5;a:3:{s:5:"Title";s:10:"Misc Links";s:3:"Url";s:40:"http://blankmediaoutlet.com/page/1041120";s:8:"ClickUrl";s:40:"http://blankmediaoutlet.com/page/1041120";}i:6;a:3:{s:5:"Title";s:84:"Travel Argentina Chile, cruises, honeymoons, accessible wheelchair, tailormade tours";s:3:"Url";s:47:"http://travel-chile-argentina.korke.com/ukl.htm";s:8:"ClickUrl";s:47:"http://travel-chile-argentina.korke.com/ukl.htm";}i:7;a:3:{s:5:"Title";s:21:"Rachmistrz Prace Blog";s:3:"Url";s:41:"http://hotjobs.taragana.com/index.php/pl/";s:8:"ClickUrl";s:41:"http://hotjobs.taragana.com/index.php/pl/";}i:8;a:3:{s:5:"Title";s:21:"Ra?unar Poslovi Blog";s:3:"Url";s:41:"http://hotjobs.taragana.com/index.php/sr/";s:8:"ClickUrl";s:41:"http://hotjobs.taragana.com/index.php/sr/";}i:9;a:3:{s:5:"Title";s:22:"Ra?unalo Poslovi Blog";s:3:"Url";s:41:"http://hotjobs.taragana.com/index.php/hr/";s:8:"ClickUrl";s:41:"http://hotjobs.taragana.com/index.php/hr/";}i:10;a:3:{s:5:"Title";s:38:"PHP MySQL: trying to retrive birthdays";s:3:"Url";s:36:"http://www.ozzu.com/ftopic75979.html";s:8:"ClickUrl";s:36:"http://www.ozzu.com/ftopic75979.html";}i:11;a:3:{s:5:"Title";s:43:"??????????s ????????

serialize is a wonderful php method to convert an array of any kind to a string representation. To reverse the operation, there is unserialize starting from the string. Very useful to persist any kind of structured information in a text-oriented storage.
