1. 對于Windows + Apache服務器來說，下載VC6 + Thread Safe版本。
?
2. 安裝好PHP后，需要確認PHP的路徑在PATH中設定完畢；然后修改Apache的httpd.conf文件，加入如下二行：
#
LoadModule?php5_module?"C:/Program?Files/PHP/php5apache2_2.dll"
AddHandler?application/x-httpd-php?.php
#?configure?the?path?to?php.ini
PHPIniDir?"C:/Program?Files/PHP"
需要注意裝載的dll版本。
?
3. 如果安裝后在命令行運行出錯，那么
do:
php -n -v
if it works, that means you are loading extensions with missing dependencies.
Open your php.ini and verify which extension it loads.
?
4. 啟動Apache服務器，測試頁面，
<?php
??phpinfo();
?>
