iis7下的php实现urlrewrite，并隐藏index.php

<rewrite>
 <rules>
 <rule name="OrgPage" stopProcessing="true">
 <match url="^(.*)$" />
 <conditions logicalGrouping="MatchAll">
 <add input="{HTTP_HOST}" pattern="^(.*)$" />
 <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
 <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
 </conditions>
 <action type="Rewrite" url="index.php/{R:1}" />
 </rule>
 </rules>
 </rewrite>
