Check Gmail IMAP via PHP for new messages in a loop -

-

i studying application trigger php script based on new imap emails arriving on gmail. what's best way know new email has arrived on gmail imap account? can't think of configure cron job. running php + nginx on linux (ubuntu) box.

i found out that's way celular companies developers doing verify clients gmail.

well, start making connection normaly, then:

$t1=time();//mark time in $tt=$t1+(60*1);//total time = t1 + n seconds  do{     if(isset($t2)) unset($t2);//clean @ every loop cicle     $t2=time();//mark time     if(imap_num_msg($imap)!=0){//if there message (in inbox)          $mc=imap_check($imap);//messages check         //var_dump($mc); die;//vardump see data possible imap_check() , them customize       }else echo 'no new messagens';      sleep(rand(7,13));//give google server breack     if(!@imap_ping($imap)){//if connection not         //start imap connection normal way did @ first     }  }while($tt>$t2);//if total time not achivied yet, beginning of loop

and that's it.

by way, here's informations how imap works. point that: imap makes possible mantain virtually kind of "live sync" connection, if don't want configure mta receive email (like me), imap real option "email pusshed" you.

  • the connection stays active 5 10 minutes each time connect email, unless manually disconnect
  • gmail limit each account 10 simultaneous connections.
  • an imap account, though, shoud check mailbox , keep active channel imap server (imap-idle) preset industry standard of 29 minutes before times out. if set auto-retrieve setting between 20-30 minutes, should keep phone connected remote imap box.
  • when gmail gets email should send response imap idle session , mobipush should pick instantly.
  • all schedule retrieve gmail mail every 10 minutes, option sync incoming e-mail when arrives @ gmail servers.

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
