php4和php5的配置异同比较_PHP

配置php4或者php5的过程中,php4,5的配置的步骤大致一样的,但是配置内容有一些差别。在LINUX等环境下编译,一般来说,只要编译的选项正确,配置也就正确了;在windows配置则需要注意以下不同点:
1. php4ts.dll 和 php5ts.dll
这个文件要拷贝到apache的bin目录下或者系统目录下
2. httpd.conf 文件加载的模块
示例如下:
# For PHP4 + apache1.x.xx
LoadModule php4_module d:/www/webserver/php4/sapi/php4apache.dll
AddType application/x-httpd-php .php

# For PHP4 + apache2.x.xx
LoadModule php4_module d:/www/webserver/php4/sapi/php4apache2.dll
AddType application/x-httpd-php .php

# 其中d:/www/webserver/php4是php的所在目录。

# For PHP5 + apache1.x.xx
LoadModule php5_module d:/www/webserver/php5/php5apache.dll
AddType application/x-httpd-php .php

# For PHP5 + apache2.x.xx
LoadModule php5_module d:/www/webserver/php5/php5apache2.dll
AddType application/x-httpd-php .php

# 其中d:/www/webserver/php5是php的所在目录。

3. 加载mysql的方式不同

在php4以及以前的版本中,mysql是集成在php中的;
而在PHP5(包括BETA)版本,mysql是作为一个模块加载的,需要设置php.ini来加载,例如
extension_dir = "D:/www/WebServer/PHP5/ext/"
extension=php_mysql.dll

另外,PHP4,PHP5都需要系统目录下的libmysql.dll的支持,如果版本不对,即使你设置了正确的extension_dir和php_mysql.dll的参数,也会造成apache启动的时候提示phpp_mysql.dll找不到的错误。

欢迎大家讨论和指正。

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
