Length parameter must be greater than 0...?

[3raser]

$file = 'includes/views.txt';
$f = fopen($file, 'w+');
$views = fread($f, filesize($file));
fwrite($f, $views+1);
fclose($f);

 

The contents of views.txt is:

1

 

Why is it returning it needs to be greater than 0?...The file isn't empty.

Forgot the error:

Warning: fread() [function.fread]: Length parameter must be greater than 0 in /home/content/63/8895563/html/index.php on line 6

Check the PHP manual for exactly what the w+ mode means:

'w+' Open for reading and writing; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.
