使用下面的函數可以擷取任何網域名稱使用者的完整細節 function whois_query($domain) { // fix the domain name: $domain = strtolower(trim($domain)); $domain = preg_replace('/^http:\/\//i', '', $domain); $domain = preg_replace('/^www\./i', '', $domain); $domain =

這個程式碼片段可以方便你禁止某些特定的 IP 位址訪問你的網站 if ( !file_exists('blocked_ips.txt') ) { $deny_ips = array( '127.0.0.1', '192.168.1.1', '83.76.27.9', '192.168.1.163' );} else { $deny_ips = file('blocked_ips.txt');}// read user ip adress:$ip =

如果你需要下載特定的檔案而不用另開新視窗，下面的程式碼片段可以協助你。 function force_download($file) { $dir = "../log/exports/"; if ((isset($file))&&(file_exists($dir.$file))) { header("Content-type: application/force-download");

一、基本知識 通過使用 PHP 的全域數組 $_FILES，你可以從客戶電腦向遠程伺服器上傳檔案。 第一個參數是表單的 input name，第二個下標可以是 "name", "type", "size", "tmp_name" 或 "error"。就像這樣： $_FILES["file"]["name"] - 被上傳檔案的名稱 $_FILES["file"]["type"] - 被上傳檔案的類型 $_FILES["file"]["size"
