1.到php官方网站下载php，我下载的文件名是php-5.4.3-Win32-VC9-x86.zip
解压到D盘的根目录，并改名为 d:\php 把 “d:\php”和“D:\php\ext”设置为环境变量
把 php.ini-development 拷贝一份并命名为 php.ini 并做如下修改：
doc_root ="D:/Program Files/CollabNet/Subversion Server/httpd/htdocs"
extension_dir = "D:/PHP/ext/"
extension=php_bz2.dll
extension=php_curl.dll
extension=php_fileinfo.dll
extension=php_gd2.dll
extension=php_gettext.dll
;extension=php_gmp.dll
;extension=php_intl.dll
;extension=php_imap.dll
;extension=php_interbase.dll
extension=php_ldap.dll
extension=php_mbstring.dll
;extension=php_exif.dll ; Must be after mbstring as it depends on it

;extension=php_sqlite3.dll
;extension=php_sybase_ct.dll
;extension=php_tidy.dll
extension=php_xmlrpc.dll
extension=php_xsl.dll
;extension=php_zip.dll
做完配置之后在控制台用 php -v 和php -m来测试有无配置错误
2.配置apache，
在httpd.conf中添加如下行：
LoadModule php5_module "d:/php/php5apache2_2.dll"
phpinidir d:\php\php.ini
AddType application/x-httpd-php .AddType application/x-httpd-php .htm
并修改index内容如下：
重启apache，在主目录中放置测试页面 test.php
