How to upload an image from my iOS app to a PHP server? -


i don't know php , swift can me? have server: cs.hisarschool.k12.tr/ecs.php , code:

<?php  $firstname = $_post["firstname"]; $lastname = $_post["lastname"]; $userid = $_post["userid"]; $target_dir = "/var/www/html/uploads";  // $myfile = fopen($target_dir, "w");  if(!file_exists($target_dir))  {     echo "creating directory";     mkdir($target_dir, 0555, true); }  //$target_file = $target_dir . "/" . basename($_files["file"]["name"]);  $target_file = $target_dir . "/sc.jpg";  if (move_uploaded_file($_files["file"]["tmp_name"], $target_file)) {      echo json_encode([     "message" => "the file " . basename($_files["file"]["name"]) . " has been    uploaded.",     "status" => "ok",     "userid" => $_request["userid"]     ]);  } else {      echo json_encode([     "message" => "sorry, there error uploading file(" .   basename($_files["filename"][name])  . ").",     "status" => "error",     "userid" => $_request["userid"]     ]); }  ?>

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
