如题 phpStudy可以让我切换环境方便 还有一些一键功能很好用,现在比如选定 nigix+php5.3
如何安装composer呢
可能是要解决环境变量的设置?

好吧,题主我已经装成功了,这里分享一下我的经验吧。其实安装过程中最坑爹的应该是下载那个composer.phar
文件了,应该是网路的问题,题主你可以GFW一下试试效果,不过我这里是没有的。因为网络问题所以我放弃了用exe安装那个超便捷的方法,所以我是手动操作的。
首先你要设置PHP的环境变量,不过没有设置也关系不大,保证命令行能运行PHP就好了。
然后检查openssl插件有没有安装。
PHP命令行的配置文件和平常的配置文件(对应Web网站的)不是一个文件控制的,所以可能你php.ini文件里头加了openssl插件但是很可能命令行还是提示你没有加载(这也是之前我犯的错误)。
这里先推荐你装上Git Bash
,这样你就可以在CMD里面使用Linux命令了。然后运行php -i | grep openssl
看看有没有返回,如果有的话就是的确开启了。如果没有装Git Bash
的也不要紧, CMD有自带命令php -i | findstr openssl
可以用啦, 感谢 @Deloz 大大的友情提醒.
如果没有的话请先php -i | grep php.ini
看一下配置文件在哪里(同样可以换成php -i | findstr php.ini
),我这里显示的是C:\Windows
。但是比较郁闷的是在该文件夹下我没发现有php.ini文件,然后我搜索了一下发现只要把我们平常用的php.ini复制到这里来,然后修改一下文件内的extension_dir
地址到具体地址去就好了。
这会儿我们再运行php -i | grep openssl
或者php -i | findstr openssl
检查一般发现可以了。
下面再运行代码下载安装文件:curl -sS https://getcomposer.org/installer | php -- --version=1.0.0-alpha8 --filename=composer
。
我之前有单独安装过Curl
所以运行curl
命令无压力,如果不用curl
的话直接https://getcomposer.org/installer
访问这个地址复制另存下来也是没有问题的,比如你存下来的文件名为composer_install.php
,那么你接下来就要运行php composer_install.php --version=1.0.0-alpha8 --filename=composer
。
这里最好指定一下--version
这个参数,因为我没指定下载也还是失败(坑爹的网络)。多等一会儿应该就下好了(我这里是这样的),这样composer就算下载下来了。
运行的话也简单,到composer.json
当前路径下运行php composer_dir install
就好了,其中composer_dir
对应的额是你的composer文件的地址。
我用 Windows 的时候还没有 Composer,现在已经不用 Windows 了,虽然没用过 phpStudy,但是 Composer 是一个依赖于 PHP 的命令行工具,所以跟 nginx 和其它是没啥关系的。仅仅和 PHP 及系统有关系。
如何在 Windows 上安装 Composer,官网已经写的很清楚了,具体看:
https://getcomposer.org/doc/00-intro.md#installation-windows
官网+1,另外还有个比较土的方法,适用于cygwin下使用composer,直接下载的composer.phar又没有配置全局变量时:
可以将composer.phar复制至相应项目目录下运行,例如每个Symfony项目根目录下,与composer.json并列。然后使用相应的
{path}/php composer.phar xxx

出现这样的原因,你没有开启php的openssl扩展,在phpstudy中开启,然后安装就可以了。

In PHP, you can use session_status() or session_id() to check whether the session has started. 1) Use the session_status() function. If PHP_SESSION_ACTIVE is returned, the session has been started. 2) Use the session_id() function, if a non-empty string is returned, the session has been started. Both methods can effectively check the session state, and choosing which method to use depends on the PHP version and personal preferences.

Managing concurrent session access in PHP can be done by the following methods: 1. Use the database to store session data, 2. Use Redis or Memcached, 3. Implement a session locking strategy. These methods help ensure data consistency and improve concurrency performance.

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.
