I need the MongoDB PHP driver on my CentOS 5.4 machine. My PHP version is 5.1.6. I downloaded the RPM and installed it. That created several files in /usr/bin directory. I copied
/usr/bin/mongo
to
/usr/lib/php/modules
which was what extension_dir showed on doing phpinfo();.
I also added
extension=mongo.so
in /etc/php.ini.
However on executing my PHP script, i still get
Mongo class not found.
What's going wrong here ?
Also, my phpinfo() shows PHP version 5.1.6 whereas running PHP from command line shows 5.3.3. Could anything be wrong with that ?
Thanks in advance.
You're saying your webserver and command line PHP report different versions. These are going to be installed in different locations, and their extensions are API incompatible with each other.
When you installed the php_mongo extension, it may have used the command line php to determine the directory to install the extension to.
Make sure you have the correct php_mongo for the php version of your webserver, and it is in the correct extensions directory. (get the directory from the php.ini returned by phpinfo())
I hope you realise PHP 5.1 is also many years out of date. Unless you have a specific reason to use a version that old, you should also look at upgrading to a more recent version.
Edit:
Just read your comment "I must also mention that /usr/bin/mongo is a binary executable file but its not having a .so extension. Im copying it as is to /usr/lib/php/modules"
No no no! :)
This is the mongo command line client. This is not the PHP extension!
You can run a find /* -name "mongo.so" to see where the installer put the file, this will probably also give you an indication of which version of PHP it was installed for.
It looks as though you are confusing the RPM-packages for the MongoDB server with the requirements to install the MongoDB PHP driver. The PHP driver provides access to the server from your PHP applications, and does not install any command line tools.
restart httpd !
yum service httpd restart

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/20131226/memcached.so' - /usr/lib/php/20131226/memcached.so: undefined symbol: php_msgpack_serialize in Unknown on line 0
Earlier today, I enabled forwarding of messages to root#localhost on my server to beam back to my personal email.
I have been receiving the above error message at 30 minutes intervals since. Of course, I checked and there's a PHP session cleaning script attached to cron to run at 30 minutes interval.
I have been searching around but couldn't find any specific solution.
My setup:
memcached 1.4.25
PHP 7.0
nginx/1.10.0
mysql Ver 14.14 Distrib 5.7.13
Ubuntu Server LTS 16.04
The closest I found to my issue above was this: http://community.rtcamp.com/t/php-warning-error-php-msgpack-serialize/6262 but there's no answer on that thread.
First you need to work out which PHP ini files are being loaded. From command line you can run php --ini. Technically apache/nginx can be running a different version, and you can look up using phpinfo(); exit(); test script if you want to view that one instead. As you're using cron, you're using the command line version anyway.
In one of these files you will find a line similar to:
extension="memcache.so"
If you don't need this extension at all, then just comment it out by prepending it with a ;:
;extension="memcache.so"
If you DO need the extension then it sounds like you need to rebuild this module. The easiest way is using PECL.
pecl install memcache
You might need to follow some instructions whilst running the install. Once it's done, you should be able to run php -v and it shouldn't output the same warning. If this has worked and you just see the php versions, you should restart nginx (if you need it on the website, the command line one should work instantly). :
sudo service nginx restart
I guess you can get a help from a similar topic on the site here.
But briefly, one of your extensions is loading memcache and the path in that is not correct.
You should find it in your php.ini and fix the path manually.
It means there is an extension=... or zend_extension=... line in one of your php configuration files (php.ini, or another close to it) that is trying to load that extension : ixed.5.2.lin
Unfortunately that file or path doesn't exist or the permissions are incorrect.
Try to search in the .ini files that are loaded by PHP (phpinfo() can indicate which ones are) - one of them should try to load that extension.
Either correct the path to the file or comment out the corresponding line.
Check if msgpack extension is installed and enabled (php -i | grep msgpack).
It seems that PHP in Ubuntu is compiled with it by default.
If it's installed and enabled, then check you memcached extension. Maybe you are using it from a previous installation or something similar.
tl;dr: I eventually had to clear everything PHP that is less than php7.0 from my server manually, along with their related cron jobs.
Long story:
Going through my running process (ps -aux | grep 'php'), I realized php5 is still in there running. Everything on my server uses PHP7, so that lingering process was redundant, plus there was a cron job that runs a session cleaning job on the php5 somewhere, using a script which goes looking for the so-called missing Memcached file.
After removing all phps that are less than php7 from system via apt, I also went in to delete all the existing folders that are less than php7 in /usr/lib/php5 and or /usr/lib/php/ along with their cron related jobs found in /etc/cron.d/php5 and or /etc/cron.d/php/
No more whining warnings from PHP session cleaning about memcache
I was getting a similar error with memcache.so and I noticed there was a new version of memcache that was installed the moment the system ran 'pecl install memcache' (automatically that updated to the latest version). The new version caused that error so I had to change the version 1 version lower to pecl install memcache-4.0.5.2 and it worked. Thanks #Farkie for that insight, that's when I realized that there was a new version that just came out a few days ago and that was it!
Just install msgpack extension and the error message should disappear:
apt install php-msgpack
You might also be missing igbinary extension:
apt install php-igbinary
I have successfully installed Mongodb on my win 7 system. I also installed php extension for MongoDB on my Wamp server and it works perfectly; yet I wish to know how I can use MongoDB in my laravel4 projects. I will like to use mongovel package but when I run 'composer update' there is always an error: php extension not found in your system. Also I installed jessengers package but got an error: MongoClient not available. Please I need help on how to get out of this. Thanks
You need to make sure that the extension is also available on the command line. In many cases there is a different php.ini for CLI. You can find this out by running:
php --ri mongo
if that does not provide any sort of output about version and settings, you don't have it installed properly.
Then you can use php --ini to find out where your INI files are - the ones that are used for running PHP on the command line
I am new to Node.js and MongoDB. I have successfully got the mongoDB running with node.js and am able to start it up and store data inside of collections. So the server is already running on localhost:27017 and works when accessing localhost:28017 .
Now that I have it running and working within Node, I wanted to test MongoDB out with PHP on my Xampp server running on Ubuntu, but am not able to get the phpinfo() to say it is using mongo yet.
I have followed the steps here to configure and install the driver. I have moved the mongo.so file to my xampps extensions and added the appropriate line in php.ini + restarted. But phpinfo() still doesn't show it.
I guess i am confused on the aspect of where do i put the mongo-php-driver folder? is this installed into the Xampp server as well, if so where do i put it?
It is already running and working using node.js , so was just getting confused why it wasn't working properly or getting connected.
Also while I'm at it, Is it possible to have php and node.js use the same mongoDB server running on port 27017?
EDIT:
I was able to get the server to at least give me an error message about the file after i edited the extension_dir to the correct path
extension_lib = "/opt/lampp/lib/php/extensions/no-debug-zts-20090626"
i am now getting this error
Warning: PHP Startup: Unable to load dynamic library '/opt/lampp/lib/php/extensions/no-debug-non-zts-20090626/mongo.so' - /opt/lampp/lib/php/extensions/no-debug-non-zts-20090626/mongo.so: wrong ELF class: ELFCLASS64 in Unknown on line 0
i guess I needed to change that php.ini option to get it to load properly. but it seems I have compiled the wrong mongo.so build. I try again.
Thanks
According to this:
http://montenasoft.com/en/blog/how-install-pecl-php-extension-64bit-linux-while-you-are-using-32bit-xampp
Because xampp is compiled with 32 bit, but the mongo driver you compile is 64 bit.
You may have to compile your mongo driver with these:
phpize
CFLAGS=-m32 CPPFLAGS=-m32 CCASFLAGS=-m32 ./configure
make
sudo make install
Or just install apache2, mysql, php separately. I think this is a better option.
I am trying to compile the imagemagick (imagick) extension to use in a non-thread-safe environment on windows.
I am using PHP 5.3.10 and have set up Visual C++ express as my compiling environment.
The problem is that I am using a non-thread-safe version of PHP as a FCGI module in Apache 2.2.
Thus, my PHP is supplied with a php5.lib and not a php5ts.lib. I believe this is the reason why I am getting these errors:
imagick.obj : error LNK2019: unresolved external symbol __imp__tsrm_mutex_alloc referenced in function _zm_startup_imagick
I have only ever built and compiled things on linux, so am not too sure how to do this on a windows environment.
How can I compile the extension so that it is non-thread-safe?
I downloaded the threadsafe binary of PHP 5.3.10 to get a copy of php5ts.lib. I was then able to compile the extension.
I am guessing that setting the ZTS preprocessor directive to either 1 or 0 would cause the extension to compile as either threadsafe or non-thread-safe. (Not too sure about this, so if someone could let me know if this is correct or not, it would be much appreciated. :) )
I then set up a virtual machine running Windows 7 and installed the latest version of WAMP. Reason being that it used a threadsafe version of PHP.
I placed the dll in the ext folder in the PHP installation and enabled it in php.ini. However, even after trying both the ts and nts version in WAMP, I would get:
PHP Warning: PHP Startup: Unable to load dynamic library 'c:/wamp/bin/php/php5.3.10/ext/imagick.dll' - The specified module could not be found.
in Unknown on line 0
But the thing is that c:/wamp/bin/php/php5.3.10/ext/imagick.dll' does exist, and yes I have checked this a lot of times.
I then downgraded ImageMagick to 6.6.2-10-Q16, but still see the same problem.
The same issue occurs on my dev machine running a nts version of PHP 5.3.10 on Apache 2.2 (all installed manually).
Looks like I could be wrong regarding the ZTS preprocessor. If I set ZTS=0 and compile, using dependency walker on the compiled dll still shows that it requires php5ts.dll which is only present on threadsafe versions of PHP.
I did more tinkering with dependency walker and found that I had to statistically link to msvc100d.dll. I then removed ZTS in the preprocessor definition and was able to compile using php5.lib instead of php5ts.dll. I think this should get me a non-ts dll.
However, when loading the extension, I am still getting:
PHP Warning: PHP Startup: Invalid library (maybe not a PHP library) 'imagick.dll' in Unknown on line 0
And errors from dependency walker:
Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.
Error: Modules with different CPU types were found.
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.
Installed visual c++ express 2008 and compiled using platform toolkit v90, but still facing the same issues.
Any tips appreciated :)
Solution Found! See my answer.
Got it! I hope this can help those compiling php extensions on windows in the future. What I have done is based on: https://wiki.php.net/internals/windows/stepbystepbuild
Note: I read an answer on this site that said compiling PHP extensions by itself on windows is unsupported. Based on my experiments yesterday, it seems to be a lot of work as well, so I am using the PHP build process.
The best way is to use the PHP build process.
Install Visual C++ Express 2008 (any version will do, but express is free) and Windows SDK 6.1 (note that we want the 6.1 version not anything older or newer).
Install the SVN client tools if you haven't done so and restart for your PATH variable to take effect.
Get the PHP SDK binary tools and extract it to C:\php-sdk.
Start the CMD Shell under Microsoft Windows SDK v6.1 in your start menu and run cd C:\php-sdk.
Run setenv /x86 /xp /release this creates a 32-bit release. You can use /x64 to build a 64-bit release (I have not tried this).
run bin\phpsdk_setvars.bat
run bin\phpsdk_buildtree.bat php53dev
Download the PHP source code and extract it to C:\php-sdk\php53dev\vc9\x86 so that you end up with C:\php-sdk\php53dev\vc9\x86\php5.3-xyz
Download the latest deps and extract everything to C:\php-sdk\php53dev\vc9\x86. You may be prompted to overwrite any existing folders, so press yes.
run cd C:\php-sdk\php53dev\vc9\x86
Check out the latest version of your extension from the svn repository: svn co http://svn.php.net/repository/pecl/imagick/trunk pecl/imagick I am checking out imagick here.
Install any dependencies. In my case, I need to install ImageMagick, so I downloaded the latest recommended windows binary. You will need to restart after installation to update your PATH variable, but you can do this after you have compiled. Make sure you install the C/C++ headers and includes as well.
Copy the contents of the includes directory from the ImageMagick install directory to C:\php-sdk\php53dev\vc9\x86\deps\include.
Copy the contents of the lib directory from the ImageMagick install directory to C:\php-sdk\php53dev\vc9\x86\deps\lib
Now, let's build: run cd C:\php-sdk\php53dev\vc9\x86\php5.3-xyz then buildconf then configure --help. Look at the help properly. It will show you all config flags and any avaliable extensions to enabled. In my case, since I added imagick, I had an option called --with-imagick
Run config: configure --enable-cli --with-imagick=shared --disable-zts If you want to build a non-thread-safe binary use --disable-zts, otherwise remove that configuration flag. I am not sure why, but sometimes extensions use the --with-myextension flag and sometimes --enable-myextension, so check configure --help for the flag to use. If you add =shared after the extension flag, it will be compiled as a separate DLL, which si what we want.
Compile: run nmake then nmake snap.
Done :) Check C:\php-sdk\php53dev\vc9\x86\php-5.3.10\Release (non-thread-safe) or C:\php-sdk\php53dev\vc9\x86\php-5.3.10\Release_TS (thread-safe). Your compiled binaries should be in there. The compiled extensions (pecl), should be in a ZIP file similiar to pecl-5.3.10-nts-Win32-VC9-x86.zip. Open this file and extract the extensio DLL to your ext folder in your PHP installation.
Enable the PHP extension and restart your webserver. Run phpinfo() and check that the extension is enabled.
If the extension does not work properly, make sure you reboot to update your PATH variable. In my case, I need to have the imagemagick install directory in my PATH variable.
???
Profit!
Is there a reason you need to compile? Why not download? It's usually much simpler/quicker on Windows.

I installed XAMPP , phpinfo: PHP Version 5.3.5
Downloaded PHPPDT, installed
downloaded webserver debug extension, copied dummy.php
added zend_extension="c:\edward\xampp\php\ext\5_3_x_nts_comp\ZendDebugger.dll"
stop, restart apache, get:
"the program cant start because php5.dll is missing from your computer"
(while php5nts.dll is included)
is installing zend studio ce the alternative or can i make it work with XAMPP? (using Zend Studio CE works)
if your php version is Non-Thread-Safe (nts)
you must use php extension with format example: extension=php_cl_dbg_5_2_nts.dll
else if your php version is Thread-Safe (ts)
you must use php extension with format example: extension=php_cl_dbg_5_2_ts.dll
(notice bolded words)
So if get error like above. Firstly, check your PHP version is nts or ts, if is nts.
Then check in php.ini whether has any line like zend_extension_ts="C:\xammp\php\ext\php_dbg.dll-5.2.x" choose right version of php_dbg.dll-5.2.x from it homepage (google for it).
Change from zend_extension_ts to zend_extension_nts.
Hope this help.
Download php5.dll (http://windows.php.net/download/) and copy it to apache/bin folder. That solved it for me (Win 7 64 bit apache 32 bit)
EDIT:
Start with the non-thread safe version.
For Wamp x86+Phalcon users (with same error):
Take care of download the right version of Phalcon:
Phalcon 1.3.2 - Windows x86 for PHP 5.5.0 (VC11)
I had the same problem I switched from wamp to xampp and yes PHP was working because my path was still pointing to my old installation. I had forgotten to change it to point to my new php installation which version of php didn't match the rest at all.
In case this might help someone, after installing the thread safe version of PHP 5.5.1, everything was working under apache for my dev sites, but I ran into the same "php5.dll is missing" problem installing Composer using the Composer-Setup.exe - or, as I soon discovered, just running something as simple as php -v from the command line. I made a copy of php5ts.dll and named it php5.dll and everything worked. I assume the Composer installer was specifically looking for "php5.dll" and I knew that the thread safe code would be run by the renamed .dll. I also assume something is wrong with my setup to screw up the command line functionality, but with everything working, I have more important issues to deal with than to try and find the problem.
I just now faced this issue while trying to restart XAMPP Apache.
What you can do to solve this is:
download PHP5.dll from http://originaldll.com/file/php5.dll/30704.html
Copy the downloaded php5.dll to C:\xampp\php
Start APACHE and MySql from XAMPP control panel
Hope my solution solves your problem.
Thank You!
I needed to change environment variable PATH and PHPRC. Also open new cmd.
I already had PHP installed and added EasyPHP when the problem came up. After I changed both variables to C:\Program Files (x86)\EasyPHP-DevServer-14.1VC9\binaries\php\php_runningversion it worked fine.
When you open phpinfo()
see if the thread safety is enable or not enable
also see the version of php
and see MSVC-- what is the number in place of --
and see the architecture
these all things help u to get the suitable php driver
here a url help u to get a php driver
https://s3.amazonaws.com/drivers.mongodb.org/php/index.html
What you can do to solve this is:
Download PHP5.dll or PHP7.dll from: http://windows.php.net/download/.
Copy the downloaded php5.dll or php7.dll to C:\xampp\php.
Start Apache and MySQL from XAMPP Control Panel.
