php - Get value and increment by one for each user -



php - Get value and increment by one for each user -

i have script cron job set run every 5 mins, problem not increment energy level believe should. if can tell me doing wrong here great. remember, returns no errors, doesn't work, database connect info correct, left out of post.

{ $energy = mysql_query("select energy members id=$id"); //get current users energy level $energy_max = mysql_query("select energy-max members id=$id"); //get current users maximum energy level if ($energy < $energy_max) // -if current energy level less maximum { $energy = $energy ++; //increment energy 1 mysql_query("update members set energy= $energy"); //set new energy level } $id++; //increment next user }

you can solve within single statement

update `members` set `energy` = `energy` + 1 `energy-max` > `energy`;

this way have 1 instead of 3 * number-of-members queries

php mysql

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
