释放双眼，带上耳机，听听看~！
添加以下代码到404.php
<?php
$error_url = 'https://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
$error_log = "silian.txt";
$entries = file($error_log);
$check=true;
foreach($entries as $f){
if($f == $error_url."n")
$check = false;
}
if($check){
$fp = fopen($error_log,"a");
flock ($fp, LOCK_EX) ;
fwrite ($fp, $error_url."n");
flock ($fp, LOCK_UN);
fclose ($fp);
}
?>
https://你的网站/silian.txt 这个文件就是记录网站的所有死链的文件。
