こんにちは、私は php のまったくの初心者で、phpjunkyard.com からこの最新の PHP テキスト ヒット カウンター スクリプトを取得して、動的ページのカウンターを自動的に生成しようとしています。ページごとに counter.txt ファイルを作成する必要はありません。これまでのところ、新しいページが存在しない場合はすべての新しいページに新しい.txtを書き込むように管理していますが、エラーが発生し、削除する方法がわかりません.. PS:このカウンターを使用しているためユニークな訪問者カウントシステムがあります。
これは元の完全な PHP ファイルです。

// SETUP YOUR COUNTER
// See file readme.html for detailed instructions
// Count unique visitors? 1 = YES, 0 = NO
$count_unique = 0;
// Number of hours a visitor is considered as "unique"
$unique_hours = 24;
// Minimum number of digits shown (zero-padding). Set to 0 to disable.

そして、これは私が変更したものです(82行目):
から:
/* Does the log file exist? */
if ( ! file_exists($logfile) )
{
die('ERROR: Log file not found. Make sure there is a file called <b>' . $page . '.txt</b> inside your <b>logs</b> folder. On most servers file names are CaSe SeNSiTiVe!');
}
に:
/* Does the log file exist? */
if ( ! file_exists($logfile) )
{
fopen($logfile, 'w') or die("can't open file");
}
そのため、次のような ID ごとに異なるページごとに .txt を使用して新しいカウンターを作成しました。
<script language="Javascript" src="http://www.website.com/counter.php?page=<?php echo $pageid();?>">
しかし、これは.txtファイルを作成しているときに初めて新しいIDを使用したときに発生するエラーです:
Warning: fread() [function.fread]: Length parameter must be greater than 0 in /home/u716430538/public_html/counter14/counter.php on line 95
document.write('1');
その後、同じ ID を開くと、通常どおりに表示されます。
document.write('1');
私の悪い英語で申し訳ありませんが、誰かが私を助けてくれることを願っています. ありがとう
