title: Error for Apache2.2.15 configuration with PHP5
body: <p>I am trying to configure <strong>apache 2.2.15</strong> with <strong>php5</strong> in my linux system. I have installed both of them. But when I added <strong>libphp5.so</strong> module in <code>httpd.conf</code> of apache, it has given  the following error while starting the server:</p>
  
  <blockquote>
    <p>Starting httpd: httpd: Syntax error on line 202 of /etc/httpd/conf/httpd.conf: Cannot load /etc/httpd/modules/libphp5.so into server: /etc/httpd/modules/libphp5.so: undefined symbol: ap_unixd_config</p>
  </blockquote>
  
  <p>Can anybody tell me how to fix this, as I tried every possible solution by googling it but in vain?</p>
