Simple Counter PHP

A very simple counter in php.
Saves the page counts of a webpage in a textfile (.txt) and writes it on the page.

/* counter */
$datei = fopen("countlog.txt","r"); //opens countlog.txt to read
$count = fgets($datei,1000);
fclose($datei);
$count=$count + 1 ;
echo "3\" FACE=\"arial, verdana, helvetica\">you are vistor no." ;
echo "3\" FACE=\"arial, verdana, helvetica\">$count" ;
echo "\n
" ;
$datei = fopen("countlog.txt","w"); // opens to write and deletes the old count
fwrite($datei, $count);
fclose($datei);
?>
