i'm wondering, php session, preferred store session variable containing logged in user's id or username? at moment stores username, whereas id safer because potential "hackers", may not know user id correlates to? php sessions work giving "opaque" cookie users - is, cookie number, , actual data stored on server. when user sends session cookie, php looks number in table retrieve data you've stored user. this means impossible, without access server, listening on network figure out session cookie means. need table stored on server. doesn't matter if store id number or username in session: if have enough access see what's in session, username based on id number anyway.

i'm not type post question, , more search why doesn't work first, time did could, , can't figure out wrong. so here's thing: i'm programming irc bot, , i'm using libircclient, small c library handle irc connections. it's working pretty great, job , kinda easy use, ... i'm connecting 2 different servers, , i'm using custom networking loop, uses select function. on personal computer, there's no problem loop, , works great. but (here's problem), on remote server, bot hosted, can connect 1 server not other. i tried debug could. went examine sources of libircclient, see how worked, , put printfs could, , see comes from, don't understand why this. so here's code server (the irc_session_t objects encapsulated, it's kinda easy understand. feel free ask more informations if want to): // connect first session first.connect(); // connect osu! session second.connect(); // initialize sockets sets fd_set sockets, out_socke

i want eventing more keys in javascript code: <script> function open(e) { if (e.type !== "blur") { if (e.keycode === 70) { alert("pressed f"); } } } document.onkeydown = open; </script> what getting question want detect more keys presses. best way detect key presses switch statement function open(e) { if (e.type !== "blur") { switch (e.keycode) { case 70: alert("pressed f"); break; case 65: alert("pressed a"); break; default: alert("i don't know key!");//this line removable break; } } } document.onkeydown = open; how works the way switch works is: switch (value) { case this_value: code break; default: code break; } that worst explanation you've seen can read here wi

im trying take div created , make move across screen every hour using p5.js , i'm wondering if @ possible wonderig if div can change color randomly every hour in p5.js one way use window.setinterval function. function, can perform animation every hour. however, 1 problem arises that, according p5.js documentation, draw() function executes continuously after setup() function called. can fix taking advantage of noloop() , loop functions. the noloop() function call stop draw() function executing , loop() function start execution again. so, let's take @ how can code this: note: according documentation, there can 1 draw function each sketch. so, if have other things animating throughout course of hour approach may not best choice. //stores position of element on x-axis of screen var xpos = 0; var delay = 60000 * 60; //1,000 milliseconds in second window.setinterval(function(){ //code called every hour; make draw function loop loop(); }, delay);
