I have downloaded and installed PHP 5.3.0...while i tried to copy php.ini.dist file to /usr/local/apache/php5/php.ini it says
--------------------------------------------------------------------------
[root@localhost php-5.3.0]# cp php.ini-dist /usr/local/apache/php5/php.ini
cp: cannot stat `php.ini-dist': No such file or directory
--------------------------------------------------------------------------
Then i took ls and here is the output...

Plz guide me wht should i do..?

php.ini-dist is now php.ini-production

There is a wiki entry here with some more information on the two new ini files.

Thanks for the reply but see this output..
-------------------------------------------------------------------------
cp php.ini-production /usr/local/apache/php5/php.ini
cp: cannot create regular file `/usr/local/apache/php5/php.ini': No such file or directory
-------------------------------------------------------------------------

it says cannot create regular file /usr/local/apache/php5/php.ini...Why? wht should i do now?

This is possibly because the directory '/usr/local/apache/php5' that you are copying to does not exist.

Is it supposed to be '/usr/local/apache/php' instead? (I believe that this location depends on the --with-config-file parameter that was used earlier in the installation process).

Thanks i resolved that copy issue but the new issue is this

[root@localhost bin]# ./apachectl restart
httpd: Syntax error on line 313 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/modules/libphp5.so into server: /usr/local/apache/modules/libphp5.so: undefined symbol: ap_server_root

I had add some lines in httpd.conf that are as follow:
AddType application/x-httpd-php .php .phtml
AddType application/x-httpd-php-source .phps
AddType application/x-httpd-php .php
LoadModule php5_module /usr/local/apache/modules/libphp5.so

pls tell me where i have to add lines in httpd.conf and also tell me wht exactly i have to add in httpd.conf

Is there any Linux Guru who can help me for the above problem?
