Im pretty sure this is PHP...

Everyone knows about the [b]f[/b] functions.
fopen
fwrite
fclose

Can anyone put together a small script, that will write to a file called config.php. Ill config everything else myself. Just a script that will open the file, write to it, and then close it. Please include a few text boxes.

I belive php has already done this for you

:-\ It doesnt work, It just writes the whole script over again, and if it put $_POST['varname'] I get a huge error :S.

"It doesn't work" and "huge error" really isn't going to be any help at all. We're not looking at what you wrote or what the error was. 

Perhaps if you post your code, someone will suggest functional improvements.

[code]<?php
$filename = 'config.php';
$somecontent = "<?PHP
$databasehost = $databasehost
?>";

// Let's make sure the file exists and is writable first.
if (is_writable($filename)) {

  // In our example we're opening $filename in append mode.
  // The file pointer is at the bottom of the file hence
  // that's where $somecontent will go when we fwrite() it.
  if (!$handle = fopen($filename, 'a')) {
        echo "Cannot open file ($filename)";
        exit;
  }

  // Write $somecontent to our opened file.
  if (fwrite($handle, $somecontent) === FALSE) {
      echo "Cannot write to file ($filename)";
      exit;
  }
 
  echo "Success, wrote ($somecontent) to file ($filename)";
 
  fclose($handle);

} else {
  echo "The file $filename is not writable";
}
?> [/code]
Install.php posts to this, that's where I get the $databasehost variable from.
Now, when I try to write the $somecontent It writes the whole script. Dont I have to use $_POST['var'], if I use that, I get a different error. A while back, wildteen88 posted one for me.
