ถามเรื่องโค้ดcounter หน่อยค่ะ คือว่าเขียนโค้ดนับจำนวนผู้เข้าชมทั้งหมดค่ะแต่พอกด refresh แล้วจำนวนก็เพิ่มอ่ะค่ะต้องเพิ่มโค้ดอย่างไรค่ะ

<?
$filename="number.txt";
$fp=fopen($filename,"r");
$get_number=fread($fp,filesize($filename));
fclose($fp);
session_start();
if(!$_SESSION['check_sess']){
	$_SESSION['check_sess']=session_id();
     $get_number=$get_number+1;
}
$fp=fopen($filename,"w";
fwrite($fp,$get_number);
fclose($fp);
$counter=sprintf("%05d",$get_number);
for($i=0;$i<5;$i++){
echo"<img src='images/$gcounter[$i].gif'>";
}
?>
