How to update PHP curl extension in Linux/Mac?

阅读更多关于 How to update PHP curl extension in Linux/Mac?

问题 What is the easiest way to update the curl extension in PHP? I installed XAMPP on Mac/Linux and noticed that it doesn't allow me to use HTTP2, so I thought of compiling my own curl with the --with-nghttp2 option, but how can I include this into PHP? Installing curl with brew install curl --with-nghttp2 on Mac doesn't change anything in the phpInfo(), the curl version used by PHP remains the same as before. 回答1: The reasons your phpinfo() doesn't update is because XAMPP's CURL and your

缓存数据库Memcached——安装及管理数据库操作

阅读更多关于缓存数据库Memcached——安装及管理数据库操作

一、Memcached 简介：（1）介绍： Memcached 是一个高性能的分布式内存对象缓存系统，用于动态Web应用以减轻数据库负载。它通过在内存中缓存数据和对象来减少读取数据库的次数，从而提高动态、数据库驱动网站的速度。Memcached基于一个存储键/值对的hashmap。其守护进程（daemon ）是用C写的，但是客户端可以用任何语言来编写，并通过memcached协议与守护进程通信。（2）特点： memcached作为高速运行的分布式缓存服务器，具有以下的特点： 1、协议简单； 2、基于libevent的事件处理； 3、内置内存存储方式； 4、memcached不互相通信的分布式。（3）存储方式：为了提高性能，memcached中保存的数据都存储在memcached内置的内存存储空间中。由于数据仅存在于内存中，因此重启memcached、重启操作系统会导致全部数据消失。另外，内容容量达到指定值之后，就基于LRU(Least Recently Used)算法自动删除不使用的缓存。memcached本身是为缓存而设计的服务器，因此并没有过多考虑数据的永久性问题。二、memcached数据库配置： 1、准备安装所需源码包 [root@localhost ~]# mkdir /mnt/tools [root@localhost ~]# mount.cifs //192

PHP “mail()” function sends mail from php5 cli but not when the script is run by a browser

阅读更多关于 PHP “mail()” function sends mail from php5 cli but not when the script is run by a browser

问题 I have configured my server to send mail by setting "sendmail_path = "/usr/sbin/sendmail" in "/etc/php5/apache2/php.ini" and sendmail is installed on the server. When I run this script, or any variation of it, from php5 via the cli the mail sends just fine, but when I have a browser run it, i.e. Chrome or Firefox, it fails everytime. <?php $to = "notreal@email.com"; $subject = "Hi!"; $body = "Hi,\n\nHow are you?"; if (mail($to, $subject, $body)) { echo("<p>Message successfully sent!</p>"); }

PHP resetting Session after some time

问题 I know this problem has been presented here in SO and I've tried the solutions but it's still not fixed. PHP is deleting the session after some time of inactivity (i assume 24 minutes as it's the default and seems to fit the testing). I have the following code set in all the pages: ini_set('display_errors', 0); $sessionCookieExpireTime = 2880000; session_set_cookie_params($sessionCookieExpireTime); ini_set('session.gc_maxlifetime', $sessionCookieExpireTime); session_start(); echo ini_get(

How to handle large amounts of scheduled tasks on a web server?

阅读更多关于 How to handle large amounts of scheduled tasks on a web server?

问题 I'm developing a website (using a LAMP stack) which must handle many user-made scheduling tasks. It works as following: an user creates an event and sets a date, and others users (as many as 63) may join. A few hours before the set date, the system must email each user subscribed to that event. And that's it. However, I have never handled scheduling, and the only tools I know (poorly) are cron and at. My plan is to create an at job for each event, which will call a script that gets all
