Use PHP to Read or Write to a file that is in aother / Different Foder

[woocha]

Hey Guys,

Here is some code that I have been working on and I can not seem to get it right...I am learning how to write to a file....Pretty awesome...I understand how it works, but I need to know if I can run my script in this location ( home/folderA ) and edit a text file in this location ( home/folderB ).....I know the file is being read, but the file will not change or update.

// Checking our file
  $file = "../soda.txt";

// does the file exist?
 if(file_exists($file)) 
{


// is it readable?
  if(is_readable($file)) 
  {
    echo $file." is readable! <br/>";
  }


// is it writable?
  if(is_writable($file)) 
  {
	echo $file." is writable! <br/>";

$fh = fopen($file, 'w') or die("can't open file");
$stringData = "$htpasswd_text";
fwrite($fh, $stringData);
fclose($fh);
  } 

}

// file does not exist
 else { 
   echo("The File Does Not Exist");	
 }


   echo "<p><hr></p>"; 
   echo "Your file has been updated!"; 
   echo "<p><hr></p>"; 

Can you guys take a look and tell me why I can't write to the file....
Thanks

Is the file writable, and is $htpasswd_text defined somewhere? Because it could be that that variable isn't being set, so it's writing nothing to the file.

Yes it is writable....the script wopuld tell me if it isn't..., right? yes that variable is defined above, I forgot to copy that part....
