Eg1 html head titleHELLO ＷORLD! /title /head body !—以上为普通html代码，以下为php代码-- ? echo “HELLO WORLD!”; ? !—以上为php代码-- /body /html 第2章PHP环境搭配设置 2.1安装Apache 下载Apache 2.2安装Apache 安装成功后 2.3下载PHP 首先进入/ 2.4配置Apache和PHP 1.解压缩PHP 包至C盘，文件中有php.ini-recommended（带附加安全措施）和php.ini-dist（用于开发）2个文件，这2个文件具有相同的配置值，将php.ini-dist重命名为php.ini 2配置路径 3．补充：将C:\php中php5ts.dll、libmysql.dll复制到系统目录C：\windows中 C:\php\ext下将php_gd2.dll、php_mysql.dll这2个文件复制到系统目录C:\WINDOWS\system32 重启Apache服务器。 4.把Apache配置为使用PHP 打开D:\Program Files\Apache Software Foundation\Apache2.2\conf下的httpd.conf文件，定位如下代码，为的是能把PHP文件识别为需要用PHP引擎来解析。 # AddType allows you to add to or override the MIME configuration # file specified in TypesConfig for specific file types. # #AddType application/x-gzip .tgz # # AddEncoding allows you to have certain browsers uncompress # information on the fly. Note: Not all browsers support this. # #AddEncoding x-compress .Z #AddEncoding x-gzip .gz .tgz # # If the AddEncoding directives above are commented-out, then you # probably should define those extensions to indicate media types: # AddType application/x-compress .Z AddType application/x-gzip .gz .tgz 然后添加如下代码： ScriptAlias /php/ c:/php/ AddType application/x-httpd-php .php AddType application/x-httpd-php-source .php # For PHP 4 Action application/x-httpd-php /php/php.exe # For PHP 5 Action application/x-httpd-php /php/php-cgi.exe 接着在httpd.conf文件中添加PHP模块，以便Apache与PHP能正确合作，处理PHP动态生成的页面。定位如下代码 # Dynamic Shared Object (DSO) Support # # To be able to use the functionality of a module which was built as a DSO you # have to place corresponding `LoadModule lines at this location so the # directives contained in it are actually available _before_ they are used. # Statically compiled modules (those listed by `httpd -l) do not need # to be loaded here. # # Example: # LoadModule foo_module modules/mod_foo.so # 。。。 LoadModule actions_module modules/mod_actions.so #LoadModule usertrack_module modules/mod_use
