apache不支持php了!

apache不支持php了!

在httpd.conf中加入
AddType application/x-httpd-php .php
AddType application/x-httpd-php .php3
就启动不了了,这是为什么呀?!
去掉那两行
写一个text.php显示源码
是不是还有别的要设一下呀,我装完后什么也没有改,谢谢了
你加入
LoadModule php4_module libexec/libphp4.so
了吗?

apache肯定支持php
好像加了,可是好像还是不行
[root@localhost apache]# ./bin/apachectl start
Syntax error on line 205 of /usr/local/apache/conf/httpd.conf:
Invalid command 'LoadModule', perhaps mis-spelled or defined by a module not included in the server configuration
./bin/apachectl start: httpd could not be started
我看了一下没有libphp4.so是怎么回事呀,谢了,我真的很急!!!
这个文件在哪一个目录下呀,我怎么找也是找不到:
php-4.3.4
[root@localhost php-4.3.4]# /www/apache/bin/apachectl configtest
Syntax error on line 774 of /www/apache/conf/httpd.conf:
AddType requires at least two arguments, a mime type followed by one or more file extensions

It has libphp4.so
but apache still cannot work after I type AddType application/x-httpd-php .php and
AddType application/x-httpd-php .php3
How can I deal with it ?
