在Windows下编译适用于PHP 5.2.12及5.2.13的eAccelerator.dll(附
最近PHP 5.2.12及5.2.13发布了,修复了多个bug,因此升级到这一版本是非常必要的。
首先说明一下我的一些参数:
操作系统: Windows 7 Ultimate
Web Server:Apache 2.2.14
(别嫌弃它版本老,即便是在Win7下它还是能用的,当然你用Visual Studio 2008也行)
什么是eAccelerator?
eaccelerator是一个自由开放源码php加速器,优化和动态内容缓存,提高了性能php脚本的缓存性能,使得PHP脚本在编译的状态下,对服务器的开销几乎完全消除。 它还有对脚本起优化作用,以加快其执行效率。
1.首先下载编译好的PHP二进制包。(稍后会用到) 地址如下:
2.再下载PHP的源代码,稍后编译eAccelerator的时候会用到。地址如下:
3.升级PHP:
这一过程很简单,首先关闭Apache,然后将压缩包里解压出来的所有文件替换掉原来的文件即可。例如你原来的PHP程序文件位于 D:\php,那么请将php-5.2.13-Win32.zip(或者php-5.2.12-Win32.zip)解压到这一路径下覆盖原有文件。
4.启动Apache,我们会收到一条报错信息,Apache无法启动。打开Apache的日志文件(此文件路径为apache\logs\error.log),我们会看到这样的提示信息:
代码如下:
PHP Warning: [eAccelerator] This build of "eAccelerator" was compiled for PHP version 5.2.11.
Rebuild it for your PHP version (5.2.13) or download precompiled binaries.
意思就是当前的eAccelerator是为PHP 5.2.11编译的,不适用于5.2.13。我们应该重新编译一份eAccelerator。
5.下载一份eAccelerator的源码。地址如下:
6.将第2步骤下载到的PHP源码解压到某一目录下,例如 E:\php。然后打开你的PHP程序目录(也就是你的php.exe所在的目录),找到其中dev子目录下的php5ts.lib文件,把它复制到E:\php这一位置。
7.打开E:\php\ext,在这下面创建一个目录命名为eaccelerator,然后将第5步骤下载到的压缩包解压到此目录下。此时的目录结构应该是这样的:
8.打开win32子目录,其中应该有一个名叫eAccelerator.dsw的项目文件,用VS开发环境打开它(比如我用的就是VS6.0),打开”组件”>”配置”,选中 Win32 Release PHP5 这一选项,单击“关闭”。
9.按下F7键(或选择工具条中的编辑按钮)开始编译,稍等片刻,编译成功,你就可以在win32目录下看到生成了一个Release子目录,打开这个子目录,你就会看到已经生成了eAccelerator.dll文件。
将这个文件复制到你的PHP扩展目录下(如D:\php\ext),替换掉原有的文件,然后启动Apache,你就会发现eAccelerator已经成功加载了。

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

Solving the problem of slow Photoshop startup requires a multi-pronged approach, including: upgrading hardware (memory, solid-state drive, CPU); uninstalling outdated or incompatible plug-ins; cleaning up system garbage and excessive background programs regularly; closing irrelevant programs with caution; avoiding opening a large number of files during startup.

Pull vertical guides in Photoshop: Enable ruler view (View > ruler). Hover the mouse over the vertical edge of the ruler, and then the cursor becomes a vertical line with double arrows and hold and drag the mouse to pull out the reference line.

Unable to access MySQL from the terminal may be due to: MySQL service not running; connection command error; insufficient permissions; firewall blocks connection; MySQL configuration file error.

The MySQL connection may be due to the following reasons: MySQL service is not started, the firewall intercepts the connection, the port number is incorrect, the user name or password is incorrect, the listening address in my.cnf is improperly configured, etc. The troubleshooting steps include: 1. Check whether the MySQL service is running; 2. Adjust the firewall settings to allow MySQL to listen to port 3306; 3. Confirm that the port number is consistent with the actual port number; 4. Check whether the user name and password are correct; 5. Make sure the bind-address settings in my.cnf are correct.

The solution to MySQL installation error is: 1. Carefully check the system environment to ensure that the MySQL dependency library requirements are met. Different operating systems and version requirements are different; 2. Carefully read the error message and take corresponding measures according to prompts (such as missing library files or insufficient permissions), such as installing dependencies or using sudo commands; 3. If necessary, try to install the source code and carefully check the compilation log, but this requires a certain amount of Linux knowledge and experience. The key to ultimately solving the problem is to carefully check the system environment and error information, and refer to the official documents.

The main reasons for MySQL installation failure are: 1. Permission issues, you need to run as an administrator or use the sudo command; 2. Dependencies are missing, and you need to install relevant development packages; 3. Port conflicts, you need to close the program that occupies port 3306 or modify the configuration file; 4. The installation package is corrupt, you need to download and verify the integrity; 5. The environment variable is incorrectly configured, and the environment variables must be correctly configured according to the operating system. Solve these problems and carefully check each step to successfully install MySQL.

The secrets to mastering Office software include: understanding different versions and platforms, correctly installing and configuring, proficient in using the software interface, in-depth understanding of feature operations, application collaboration and sharing functions, utilizing templates and styles, mastering advanced skills, and solving common problems.
