MongoDB Driver issues with XAMPP

[Deepan]

I have issues in PHP-Mongodb Linux installation. After following the below steps, I am not able to access webpages instead it's getting downloaded.

1) Installed MongoDB PHP driver sudo pecl install mongo

2) Added mongo.so to /opt/lampp/lib/php/extensions/no-debug-non-zts-20100525 directory

3) Added "extension=mongo.so" to php.ini file

4) restarted XAMPP sudo /opt/lampp/lampp restart

Environment: Linux Mint 14 - 64 bit

If I try commenting step 3, I can access it but getting mongo class not found exception. Any help in resolving this issue would be appreciated. Thanks.

When it gets downloaded, is it just a white page with no content?
If that is the case, please check the PHP error logs, they should shed
some light on what is happening.

Thanks for the reply Hannes. I see source code in the downloaded file and i also see the following error in php error log.

[17-Jun-2013 01:00:43 UTC] PHP Warning:  PHP Startup: Unable to load dynamic library '/opt/lampp/lib/php/extensions/no-debug-non-zts-20100525/mongo.so' - /opt/lampp/lib/php/extensions/no-debug-non-zts-20100525/mongo.so: wrong ELF class: ELFCLASS64 in Unknown on line 0

Hello Deepan

It seems like when you pecl installed you used the "pecl" command that
came with your operating system, not the one you installed via xampp.
You need to locate the pecl command that came with xampp and use that
to pecl install the mongodb driver.
I would suspect it would look something like:
$ /opt/lampp/bin/pecl install mongodb

Thanks Hannes for the reply.

I tried using the lammp pecl for mongo installation, but the installation failed. I have included the error log. Am I missing something?

sudo /opt/lampp/bin/pecl install mongo

It looks like XAMPP didn't install the PHP header files (required to build pecl extensions).

Could you tell me how you installed XAMPP so I can try to reproduce this locally and figureout how exactly to build pecl extensions for it?

tar xvfz xampp-linux-1.8.1.tar.gz -C /opt

[Hannes Magnusson]

You need to download the "Development package" and install it (tar xvfz xampp-linux-devel*.tar.gz -C /opt ).

That package includes the header files and libraries needed to build pecl extensions like mongodb.

Hannes,

The problem on accessing php file still exists.

I installed XAMMP you provided. But still the following error is thrown when I try to access php file. It's downloading the source.

[21-Jun-2013 01:53:14 UTC] PHP Warning:  PHP Startup: Unable to load dynamic library '/opt/lampp/lib/php/extensions/no-debug-non-zts-20100525/mongo.so' - /opt/lampp/lib/php/extensions/no-debug-non-zts-20100525/mongo.so: wrong ELF class: ELFCLASS64 in Unknown on line 0

[Hannes Magnusson]

It looks like your XAMMP installation is broken, mixing 64bit and 32bit libraries.

I'd recommend you start fresh and download the two xammp packages again, and run the correct pecl binary from the new installation.

If that still doesn't work, please pastebin your entire console so I can see step-by-step what you did.

Issue got resolved.

I uninstalled XAMPP and installed Apache and PHP separately. Installed Mongo driver and added mongo.so extension in php.ini as instructed.
http://docs.mongodb.org/ecosystem/drivers/php/

Now I am able to access mongodb from my PHP.
