Problems that occur when installing extensions such as wamp, xampp, phpStudy, etc.

Sometimes the installation is completed in wonder7. Generally, you need to download the php_mongo.dll corresponding to the same version as php. Link: http://pecl.php.net/package/mongo/1.6.0RC2/windows

(1) php_mongo.dll is placed in the ext folder.

(2) Modify the extensi ' in php.ini with an absolute path

(3) Add or remove the extension=mongo.dll in php.ini

(4) Restart APACHE and visit pathinfo.php, See if mongo can be loaded successfully.

Problem: When accessing pathinfo.php, I did not find that mongo can be loaded, but apache starts normally, and php startup in unknown on line 0 pops up. At this time, you can check the apache logs or the php logs. There will be this warning PHP Warning: PHP Startup: in Unknown on line 0

I searched for a long time on Baidu and Google, but I couldn’t find the specific one. The ending is so scary!

You can cmd, enter the DOS environment, enter the php installation directory, and then use php -m to check whether the extension is already available. With the extension, do the following things.

Later, after searching and analyzing the data, I found that php’s support for the mongo library depends on 3 Dynamic link libraries: libeay32.dll, libsasl.dll and ssleay32.dll. These three libraries are generally in the php directory. So generally there should be these three dynamic libraries in the bin directory of apache to work. Sometimes one or two of them are missing in the bin directory of apache in the integrated environment. You can go in and look for them yourself, or copy all three.

After copying it, restart Apache and you can load mongo without warning
