我ap+msql+php安装你看有问题没

1.安装mysql
按照教程步骤
2.安装apache
测试在浏览器里面输入 http://localhost, 出现  It works表示成功。

3.安装php
APACHE中的conf目录修改httpd.conf
增加如下行：
<IfModule mime_module> 字段里面增加如下两行
AddType application/x-httpd-php .php
AddType application/x-httpd-php .html
增加模块：
LoadModule php5_module E:/php-5.2.6-Win32/php5apache2_2.dll

php.ini放在windows目录下面
去掉mysql前面的分号
把php5ts.dll, libmysql拷贝到C:\\windows\\system32里面
测试php是否正确
<?php
phpinfo();
php>

出现undefined mysql_connect错误的原因:
1.没有把libmysql拷贝到C:\\windows\\system32里面
2.没有修改mysql前面的分号
3.修改extend_dir指向lib库

得修改如下内容：
DocumentRoot "E:/www"
<Directory "E:/www">
    #
    # Possible values for the Options directive are "None", "All",
    # or any combination of:
    #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
    #
    # Note that "MultiViews" must be named *explicitly* --- "Options All"
    # doesn't give it to you.
    #
    # The Options directive is both complicated and important.  Please see
    # http://httpd.apache.org/docs/2.2/mod/core.html#options

    #
    Options Indexes FollowSymLinks
    #
    # AllowOverride controls what directives may be placed in .htaccess files.
    # It can be "All", "None", or any combination of the keywords:
    #   Options FileInfo AuthConfig Limit
    #
    AllowOverride None
    #
    # Controls who can get stuff from this server.
    #
    Order allow,deny
    Allow from all
</Directory>
