i have user type in how want message sent defined $time variable this loop code have right now $time = $_post["time"]; ($x = 0; $x < $amount; $x++) { mail($completenum, $subject, $message, $headers); sleep($time); } the issue code messages never sent through, believe it's because sleep function halts script. ideas? php isn't correct language this, want try javascript or similar. php designed let dynamically build page when loaded. putting sleep in there, you're delaying load time of page, , server and/or browser going time out - pages aren't expected take excessively long times load, , indicates error. different browsers going different things, , you'd need modify timeout settings on if delay long one. a scripting language keeps running in browser going able kick off periodically want, , update page - want code keeps executing after page loaded. alternately, if want php only, php code store request in database, , have ...

i'm creating web-site , use html build page layout. have 1 big html document index.html . there header, middle section , footer. many scripts used form checks, animations, slider , etc. slider has several background images , different content each slide. index.html has lot of stuff in , when user loads first time quite bit of traffic used. when user fills login form, client side jquery script checks form , data posted php script server side checks performed , session started. after successful response server want index.html reload different header. came 2 solutions this: * i can load different document using ajax header container. i can redirect html document(for example index2.html has exact same code exception header container part changed. i don't both of solutions. using ajax can avoid forcing user reload traffic. seems not elegant me reloading header make white square appear in section break user's design experience , looks clunky. while it's asyn...

i know use isnan test if value equal nan. reliable? the nan property represents value “not number”. special value results operation not performed either because 1 of operands non-numeric (e.g., "abc" / 4), or because result of operation non-numeric(e.g., attempt divide zero). while seems straightforward enough, there couple of surprising characteristics of nan can result in hair-pulling bugs if 1 not aware of them. for 1 thing, although nan means “not number”, type is, believe or not, number: console.log(typeof nan === "number"); // logs "true" additionally, nan compared – itself! – false: console.log(nan === nan); // logs "false" a semi-reliable way test whether number equal nan built-in function isnan(), using isnan() imperfect solution. a better solution either use value !== value, produce true if value equal nan. also, es6 offers new number.isnan() function, different , more reliable old global isnan() function. ...

say there 5 open tabs in single browser, , using node.js , socket.io. client , server exchange packets maintain (establish) communications. will connection client lost if of 1 tab closed? how can determine if user closed browser? yes, socket.io establishes new connection every tab. you're going want using session cookies figure out user current socket.io connection communicating with.
