网站监控邮件发送方法

网站监控、功能脚本执行结果邮件：

/**
 * 邮件发送方法
 * @param string $title 邮件主题
 * @param string $content 邮件内容
 */
function send_email($title, $content) {
    //如下以get请求发送邮件，链接中不能有&符号，以斜杠替换
    $content = str_replace("&", "/", $content);
    //获取是哪里调用的本方法，可以获取文件、行数、函数名称、参数等信息
    $backtrace = debug_backtrace();
    $send_time = '发送时间： ' . date("Y-m-d H:i:s",time()) . "<br/>";
    $send_ip = '发送服务器： ' . gethostbyname(gethostname()) . "<br/>";
    $content = $send_time . $send_ip . '邮件内容： ' . "<br/>" . $content;
    //邮件发送接口,出于安全考虑，邮件接收者最好写死，通过传参不同控制邮件接受者
    $sendurl = 'http://api.baidu.com/send_email.php?type=1&title=' . $title . '&content=' . $content;
    $result = file_get_contents($sendurl);
    if ('ok' != $result) {
        //写入php错误记录日志
        error_log('PHP Warning:  邮件发送失败  in ' . $backtrace[0]['file'] . ' on line ' . $backtrace[0]['line'] , 0);
        //自定义记录邮件内容
        $message = 'PHP Warning:  邮件发送失败  in ' . $backtrace[0]['file'] . ' on line ' . $backtrace[0]['line'] . "<br/>" . $content . "\n";
        $message = str_replace("<br/>", "\n\t", $message);
        error_log($message, 3, "error.log");
        return true;
    }
}

send_email('test', 'test');

邮件发送接口可以用 PHPMailer 写，若邮件发送成功，返回 ‘ok’!

还要注意邮件内容大小，发送邮件时对邮件内容字符数有限制

/**
 * 邮件发送方法
 * @param str $title 邮件主题
 * @param str $content 邮件内容
 * @param str $email 单独发送email
 * @param int $type 测试发送设为 1
 */
function sendEmail($title, $content, $email=null, $type=null) {
    $url = 'http://api.baidu.com/send_email.php';
    $post_data = array();
    //要注意  php.ini  中对post请求传值大小的限制
    $content = substr($content, 0, 1024*1000);
    $content = str_replace("&", "/", $content);
    $content = date("Y-m-d H:i:s",time()) . "<br/>" . $content;
    !empty($type) ? $post_data['type'] = $type : false;

        $message_err = $message . "\n" . $content;
        error_log($message_err,3,"error.log");
