10段PHP常用功能代码(1)
1、使用PHP Mail函数发送Email
$to = viralpatel.net@gmail.com; $subject = VIRALPATEL.net; $body = Body of your message here you can use HTML too. e.g. ﹤br﹥ ﹤b﹥ Bold ﹤/b﹥; $headers = From: Peterrn; $headers .= Reply-To: info@yoursite.comrn; $headers .= Return-Path: info@yoursite.comrn; $headers .= X-Mailer: PHP5n; $headers .= MIME-Version: 1.0 . n; $headers .= Content-type: text/html; charset=iso-8859-1 . rn; mail($to,$subject,$body,$headers); ?﹥ |
2、PHP中的64位编码和解码
function base64url_encode($plainText) {$base64 = base64_encode($plainText);$base64url = strtr($base64, +/=, -_,);return $base64url;}function base64url_decode($plainText) {$base64url = strtr($plainText, -_,, +/=);$base64 = base64_decode($base64url);return $base64;} |
3、获取远程IP地址
function getRealIPAddr(){if (!empty($_SERVER[HTTP_CLIENT_IP])) //check ip from share internet{$ip=$_SERVER[HTTP_CLIENT_IP];}elseif (!empty($_SERVER[HTTP_X_FORWARDED_FOR])) //to check ip is pass from proxy{$ip=$_SERVER[HTTP_X_FORWARDED_FOR];}else{$ip=$_SERVER[REMOTE_ADDR];}return $ip;} |
4、 日期格式化
function checkDateFormat($date){//match the format of the dateif (preg_match (/^([0-9]{4})-([0-9]{2})-([0-9]{2})$/, $date, $parts)){//check weather the date is valid of notif(checkdate($parts[2],$parts[3],$parts[1]))return true;elsereturn false;}elsereturn false;} |
5、验证Email
$email = $_POST[email];if(preg_match(~([a-zA-Z0-9!#$%&*+-/=?^_`{|}~])@([a-zA-Z0-9-]). ([a-zA-Z0-9]{2,4})~,$email)) {echo This is a valid email.;} else{echo This is an invalid email.;} |
