php的wamp环境搭建问题

Apache php安装配置好后，目前mysql还没有安装，开启Apache时，弹出两次warning PHP Startup警告后Apache开启。
本机是通过路由器和光纤猫连接网线上网，Windows XP操作系统。

Apache httpd.conf文件配置是：

Listen 12.34.56.78:80

Listen 80

LoadModule php5_module D:/wamp/php/php5apache2_4.dll
PHPIniDir D:/wamp/php

ServerName localhost:80

AddType application/x-httpd-php .php

php.ini文件配置：

extension_dir = "D:/wamp/php/ext"

extension=php_curl.dll
extension=php_gd2.dll
extension=php_mbstring.dll
extension=php_mysql.dll
extension=php_mysqli.dll
extension=php_pdo_mysql.dll
extension=php_pdo_odbc.dll
extension=php_soap.dll
extension=php_sockets.dll

date.timezone =Asia/Shanghai

Apache错误日志：
AH00558: httpd.exe: Could not reliably determine the server's fully qualified domain name, using 192.168.x.x. Set the 'ServerName' directive globally to suppress this message
PHP Warning: PHP Startup: in Unknown on line 0
[Thu Oct 15 10:48:13.312500 2015] [mpm_winnt:notice] [pid 4044:tid 1668] AH00354: Child: Starting 64 worker threads.

将所有dll都注册了一遍，还是那样。

请各位老师指教到底哪里有错误？谢谢！

逐一关闭php扩展，发现是php_curl加载时报错，而且phpinfo()中curl没有加载上
解决办法：
第一种方法：将php安装目录下的libeay32.dll，libssh2.dll，php5ts.dll，php_curl.dll，ssleay32.dll 复制到system32目录下

第二种方法：在httpd.conf 中加载如下依赖文件

LoadFile D:/wamp/php/php5ts.dll

LoadFile D:/wamp/php/libeay32.dll

LoadFile D:/wamp/php/ssleay32.dll

LoadFile D:/wamp/php/libssh2.dll

这样配置后，Apache开启时不再弹出warning PHP Startup:

第一个警报可以用 ServerName 127.0.0.1 解决
