[problems getting mysql, mysqli, and mcrypt to load]

Hi All;

I am trying  to get some extensions to load in php 5.3.23. This was installed over 5.2.3 because 5.3 does not have an php5apache2_2.dll file. When I do a phpinfo mysql and mysqli do not show up. I have check the error logs and have seen the following, My OS is Win 7 64 bit.

 

[22-Mar-2013 12:06:07] PHP Warning:  PHP Startup: mysql: Unable to initialize module

Module compiled with module API=20090626, debug=0, thread-safety=0

PHP    compiled with module API=20060613, debug=0, thread-safety=1

These options need to match

 in Unknown on line 0

PHP    compiled with module API=20060613, debug=0, thread-safety=1

 in Unknown on line 0

 

Then in apache error.log file I noticed this:

 

PHP Warning:  PHP Startup: Unable to load dynamic library 'C:\\PHP523\\ext\\php_mcrypt.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:\\PHP523\\ext\\php_mhash.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:\\PHP523\\ext\\php_mysql.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:\\PHP523\\ext\\php_mysqli.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:\\PHP523\\ext\\php_pdo_mysql.dll' - The specified module could not be found.\r\n in Unknown on line 0

 

To me it looks like the double slashes might be the problem, but I don't know where to go to get rid of them, so am I on the right track, or is there something else wrong?
