Reasons why php_cmd.dll extension cannot be used under php5.2 and Solutions

I used php_mongo.dll vc6 ts in php5.2.13.

Added extension = php_assist.dll to PhP. ini.

After Apache is restarted, new Mongo is still unavailable. Why?

Then I tried Google, and some of them could be used in 5.3 With php_cmd.dll of 5.2. I tried it, but it still didn't work.

Therefore, Apache/logs/error. log can only be viewed.

The error message is as follows:

Error 1

PHP warning: PhP startup: Unable to load dynamic library 'd: \ Wamp \ php5.2.17 \ php_cmd.dll '-\ xd5 \ xd2 \ XB2 \ xbb \ xb5 \ xbd \ xd6 \ xb8 \ xB6 \ xA8 \ xb5 \ xc4 \ xc4 \ xa3 \ xbf \ xe9 \ xA1 \ xa3 \ r \ n in unknown on line 0

Obviously, the path of extension_dir is missing/EXT during configuration.

Restart Apache after modification

Error 2

PHP warning: PhP startup: Mongo: Unable to initialize module \ nmodule compiled with module API = 20090626, DEBUG = 0, thread-Safety = 1 \ NPHP compiled with module API = 20060613, DEBUG = 0, thread-Safety = 1 \ nthese options need to match \ n in unknown on line 0

This is because 5.3 php_cmd.dll was used at the time. I forgot to replace it with 5.2 vc6ts.

With version 5.2, restart Apache to run everything freely.

For PHP extension problems, it is intuitive to see logs/error. log. Write this blog post and take this as an example.
