The following code demonstrates how to obtain the files uploaded by users in php, and limit the file types to general image files, and finally save them to the server

  1. $allowedExts = array("gif", "jpeg" , "jpg", "png");
  2. $extension = end(explode(".", $_FILES["file"]["name"]));
  3. if ((($_FILES["file"][ "type"] == "image/gif")
  4. || ($_FILES["file"]["type"] == "image/jpeg")
  5. || ($_FILES["file"]["type "] == "image/jpg")
  6. || ($_FILES["file"]["type"] == "image/pjpeg")
  7. || ($_FILES["file"]["type"] == "image/x-png")
  8. || ($_FILES["file"]["type"] == "image/png"))
  9. && ($_FILES["file"]["size"] < 20000)
  10. && in_array($extension, $allowedExts))
  11. {
  12. if ($_FILES["file"]["error"] > 0)
  13. {
  14. echo "Return Code: " . $_FILES[" file"]["error"] . "
    ";
  15. }
  16. else
  17. {
  18. echo "Upload: " . $_FILES["file"]["name"] . "
    ";
  19. echo "Type: " . $_FILES["file"]["type"] . "
    ";
  20. echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB
    ";
  21. echo "Temp file: " . $_FILES["file"]["tmp_name"] . "
    ";
  23. if (file_exists("upload/" . $_FILES[" file"]["name"]))
  24. {
  25. echo $_FILES["file"]["name"] . " already exists. ";
  26. }
  27. else
  28. {
  29. move_uploaded_file($_FILES["file"][ "tmp_name"],
  30. "upload/" . $_FILES["file"]["name"]);
  31. echo "Stored in: " . "upload/" . $_FILES["file"]["name"] ;
  32. }
  33. }
  34. }
  35. else
  36. {
  37. echo "Invalid file";
  38. }
  39. ?>
