Creating a file to add to

[Dr Ben Warne]

So far i have this code


<?php
  session_start();
  if (!isset($_POST['submit'])) {
    echo "<form method='post'>";
    echo "  your name?<input type='text' name='uname'>";
    echo "  <input type='submit' name='submit'>";
    echo "</form>";
  } else {
    $_SESSION['uname'] = $_POST['uname'];
    echo "Welcome {$_SESSION['uname']}, your session id is ". session_id();
  }
?>


But from that i want to, on entry, create a text file that will put the session id into it to wait for another id to join

BUT i want it to search to see whether the file exists (to see if someone is already waiting) the go to a new screen

I have this code previously

$file = fopen("count.txt", "r+");
$count = fread($file, filesize("count.txt"));
fclose($file);
$count += 1;
$file = fopen("count.txt", "w+");
fputs($file, $count);
fclose($file);
echo "You are visitor $count";

That writes to a text file, but i cant adapt it. Any help would be greatly appretiated!

Take a look at the function [url=http://www.php.net/file_exists]file_exists()[/url].

You should test that the file exists before writing to it...

How do i get it to create a new file and put the session id in though?

[Dr Ben Warne]

Is there a code that creates a file and adds to it?

[Dr Ben Warne]

Ia ir function create?

[url=http://php.net/fopen]fopen()[/url] basicly opens files. But if the file doesnt exist, it creates it (and then opens it). So you just need to use [url=http://php.net/fopen]fopen()[/url] :)

for what do you want to use it?
