PHP Startup Unable to load dynamic library php_mongo.dll

Question

I'm a beginner for this. I'm trying to install mongodb driver on php.

Platform: Windows 8.1 64bit.
PHP 5.5.9
Apache/2.4.7

Followed the instruction here:http://php.net/manual/en/mongo.installation.php#mongo.installation.windows

I've tried all php_mongo.dll file with VC11 and put in php/ext folder. and added extension=php_mongo.dll in php.ini file but when I tried to start apache in xampp controller I got an error.

    Php Startup: Unable to load dynamic library
  'C:\xampp\php\ext\php_mongo.dll' -%1 is not a valid Win32 application.

I've already check my VC compilator version inside phpinfo() and it's stated there MSVC11 with architecture: x86.

it would be nice if someone can help me. Thanks. appreciate it.

Make sure you download the correct .DLL for your PHP installation. Good chance you're running apache x86, so download an x86 php_mongo.dll. Also if you're running PHP as an Apache module, make sure you pick the thread safe (ts) one and also pick this type of dll that matches the PHP version you're running.

The versions must match or else you will get a php startup error. Find these Mongo DLLs here.

I did this then I got an error libsasl.dll not found. I simply copied the libsasl.dll found in my PHP installation directory to the Apache installation directory (where httpd.exe is found). Then I restarted my Apache and it worked!

The trick here is indeed to copy the libsasl.dll from the php folder to the apache binary folder – bjori Sep 04 '14 at 22:28

"make sure you pick the thread safe (ts) one and also pick this type of dll that matches the PHP version you're running." yes! – Benten Apr 03 '20 at 19:35

For anyone googling this in 2017, the PECL Package has been updated and is now found at http://pecl.php.net/package/mongodb/1.2.9/windows

and use:

extension=php_mongodb.dll

instead of:

extension=php_mongo.dll

It worked for me, although there was already a "libsasl.dll" available in C:\xampp\apache/bin. I just replaced the copy from C:\xampp\php\libsasl.dll to C:\xampp\apache\bin\ and it did the trick – Prashanth kumar Nov 14 '17 at 23:36

If you are still having problems after doing the above, do try older version drivers instead.

That is what worked for me on for my XAMPP/ PHP 5.5 on windows 8.

Older drivers can be found here: https://s3.amazonaws.com/drivers.mongodb.org/php/index.html

New drivers can be found here: http://pecl.php.net/package/mongo/1.5.5/windows

This is normally because we use 64 Bit supported DLL file 64 Bit system. But the wamp/xampp architecture could be 32 Bit. We need to use based on the wamp/xampp architecture not the windows architecture. So, try to find relevant version of DLL file to the wamp/xampp architecture. The solution in the below link worked like a charm to me,

This link helps you to find the wamp/xampp architecture, https://stackoverflow.com/a/22454865/4874281

Yes bitnami wamp turned out to be 32bit. Can't believe that worked. – user5389726598465 Jul 19 '18 at 07:34

After doing all the steps as mentioned in previous comments xampp may not be able to load the ".dll" file. Just ensure to add the path of the ".dll" file's folder to the environment variable as a system variable path.

I was facing same issue, then after adding the path of the ".dll" file's folder to the environment variable as a system variable path, it worked. It is then able to find the file.

At the end that was the only step which was stopping xampp to load the ".dll" file, although it was present in that folder. Often people miss this step as it is no where pointed out clearly.

My PHP version is 7.2.3 x86

Go to this website and pick DLL according to php version:

https://pecl.php.net/package/mongodb/1.4.2/windows

And set this in php.ini

extension=mongodb
