按照楼上的说法安装了,在安装过程中找不到extension=php_calendar.dll、extension=php_zlib.dll,完成后打开一个php文件弹出一个对话框如图:
图片如下:

单击确定后出来以来英文:
Security Alert! The PHP CGI cannot be accessed directly.
This PHP CGI binary was compiled with force-cgi-redirect enabled. This means that a page will only be served up if the REDIRECT_STATUS CGI variable is set, e.g. via an Apache Action directive.
For more information as to why this behaviour exists, see the manual page for CGI security.
For more information about changing this behaviour or re-enabling this webserver, consult the installation file that came with this distribution, or visit the manual page.
PHP Warning: Unknown(): Unable to load dynamic library './php_ldap.dll' - 找不到指定的模块。 in Unknown on line 0
请问是怎么回事,我看过很多安装php的文章,每篇都不同,我现在也不知怎么办了。
