php - Append a number to a filename if an image with that name already exists -


i wrote php checks if file exists when user uploads new file, , if appends string filename. want number added end of filename , when file same name uploaded tops number 1.

so example: have image uploaded filename image.png , upload 1 same filename. file should renamed image0.png. when try upload image filename image.png should renamed image1.png , on.

i'm not sure how accomplish within code. can me out? code snippet checks duplicates , appends filename.

if(file_exists("/customers/d/8/e/frankkluytmans.nl/httpd.www/testsite/cms/upload/".$_files["image"]["name"])) {     $filename = explode(".",$_files['image']['name']);     $imagename = $filename[0]."hoi.".$filename[1]; } else {     $imagename = $_files['image']['name']; }  $image = mysql_real_escape_string(htmlspecialchars("/upload/".$imagename));  if (move_uploaded_file($_files["image"]["tmp_name"],     "./upload/".$imagename)) {�  mysql_query("insert frankkluytmans set pagid='$pagid', title='$titlename', content='$contentname', image='$image', youtube='$youtube'") or die(mysql_error());   header("location: index.php");   }

you use recursive function keep checking number:

function checkfile($path, $file, $ext, $number) {     if(file_exists($path.$file.$number.$ext))     {         if($number == "")             $number = 0;          $number ++;         return checkfile($path, $file, $ext, $number);     }      return $path.$file.$number.$ext; }  //run mime type things extension. lets pretend .jpg // , assume stripped extension uploaded file... // also, pass blank last param start file check without number.  $extension = ".jpg"; $filename_minus_extension = "some-image";  $filename = checkfile('path-to-directory/', $filename_minus_extension, $extension, "");

this in no way tested, general idea use recursive function. if have specific question, feel free ask , may update.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
