Unable to load dynamic library

Having crossed swords with MySQL I am now trying to install and setup
Apache and PHP. While Apache installed ok and the window indicates
that it is running ok and as a third check I have accessed the server
from outside and got and edited the default html I have a problem with
PHP

The error.log shows two lines:

PHP Warning: PHP Startup: Unable to load dynamic library 'C:\\Program
Files\\PHP\\ext\\php_ifx.dll' - The specified module could not be
found.\r\n in Unknown on line 0
PHP Warning: PHP Startup: Unable to load dynamic library 'C:\\Program
Files\\PHP\\ext\\php_netools.dll' - The specified module could not be
found.\r\n in Unknown on line 0

The relevant bit of the httpd.conf looks like this:

#BEGIN PHP INSTALLER EDITS - REMOVE ONLY ON UNINSTALL
PHPIniDir "C:/Program Files/PHP/"
LoadModule php5_module "C:/Program Files/PHP/php5apache2_2.dll"
#END PHP INSTALLER EDITS - REMOVE ONLY ON UNINSTALL

Can anyone explain why I get \\ in the program line in the error log
as I think this must be the cause the module is not found and loaded.
Where does it come from?

Thanks in advance
