I have...
1.compiled and made ssh2.so.
2.placed the PHP extension (ssh2.so) in the "extension_dir"
3.been editing the correct php.ini file (extension=ssh2.so), the file "Loaded
Configuration File" entry listed in the phpinfo() output.
4.restarted apache server.
but, "php -m" prints no ssh2 module.
any idea?
For php -m to show the ssh2 module, you have to edit the CLI php.ini for that.
There are generally TWO php.ini, one for Apache module and the other for the CLI version of PHP.
In Ubuntu, you will edit /etc/php5/cli/php.ini, but YMMV
Oh, and the syntax is very much the same, so a copy-paste should do the job.
Hope this helps !
It is not php -m that you want to do but rather to create a php file in your web site containing:
<?php
phpinfo();
?>
Accessing this via Apache will show you what modules are loaded. You may want to configure Apache to secure access to this.

I run a PHP script and get this error:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20090626/ixed.5.2.lin' - /usr/local/lib/php/extensions/no-debug-non-zts-20090626/ixed.5.2.lin: cannot open shared object file: No such file or directory in Unknown on line 0
What does that mean?
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.
If you're on Linux, you can find all loaded configuration files by typing this in shell:
php -r "print phpinfo();" | grep ".ini"
UPDATE:
As mentioned in comments, this can be even more accurate:
php -i | grep ini
phpStom with XAMPP
TL;DR Except from verifying that the files exist, you might need to add the drive letter to some records in your php.ini file
I suddenly started having a problem using phpStorm 7 for debugging php with xampp and xdebug. When trying to set intellij interperter to be xampps php I got a lot of the warnings like the one in the question, for example:
Unable to load dynamic library '/xampp/php/ext/php_bz2.dll'
For some reason I had to add my drive letter to the records of extension_dir and browscap in the php.ini file:
extension_dir = "\xampp\php\ext"
browscap = "\xampp\php\extras\browscap.ini"
to
extension_dir = "e:\xampp\php\ext"
browscap = "e:\xampp\php\extras\browscap.ini"
If you just want to make the error disappear, and you don't need the extension, then by all means comment the line out in php.ini. But if you actually want to fix the problem here is some additional info.
There are various causes for this based on the exact module, but there are also some general guidelines.
Open phpinfo() and look for extension_dir under the Core section. This is where your modules should be located.
For instance, /usr/lib/php/modules for Unix/Linux.
If the file does in fact exist, make sure permissions are adequate.
If the file does not exist, use the resources below to install it.

Loading .dll in Linux
I've encountered this warning message while I was trying to install a php-extension via the php.ini file;
until I figured out that you cannot load .dll extensions in Linux,
but you have to comment the extensions that you want to import ;extension= ... .dll and install it correctly via sudo apt-get install php-...
note: ... is the extension name you want to enable.
php -r "echo php_ini_loaded_file();"
Will show in CLI current ini loaded file, search there for Your extension, path to it is incorrect.
In my case, this message started to appear when I updated the php version to 7.4.
To solve it I had to look for the php.ini files found inside the php version folder (/etc/php/7.4/apache2/ && /etc/php/7.4/cli/) checking the lines where the extensions I could see that the extensions gd2 and intl were uncommented.
Note that you can also get this error if your PHP library doesn't have the "other" directory opening permission. In my particular case, I noticed this when using php -l to syntax check a script in my text editor. This meant that since my account was called "volomike", that account didn't have permission to run the libraries that the php command relied upon.
For instance, on Ubuntu 14.04, I had PHP5 installed automatically into the path /usr/lib/php5/20121212+lfs. However, because I was working in C++ in building some shared objects, I messed around with the directory permissions and screwed things up such that non-root accounts did not have the directory execute (directory open) permissions to view /usr/lib/php5/20121212+lfs. So, I typed the following command to rectify that problem:
sudo chmod o+x /usr/lib/php5/20121212+lfs.
Now when I do php -l example.php as a non-root user, it never gives me this "Unabled to load dynamic library" problem anymore.
I had the same problem on XAMPP for Windows when I try to install composer.
I did php -v and php throwing error :
Unable to load dynamic library '/xampp/php/ext/php_bz2.dll'
It took me a while until I realized that I need to setup my XAMPP. So I run setup_xampp.bat and php return to works like a charm.
I had this error on a number of modules when I had been running different versions of PHP side by side on my server. To sort this out, I needed to install the packages it couldn't find for that specific PHP version. So, for example, if I saw:-
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/20160303/xml.so'
I would install the library for the PHP version specifically:-
sudo apt-get install php7.1-xml
And then restart Apache. Fixed it for me. You can check your version like this:-
php -v
I had the same problem on XAMPP for Windows10 when I try to install composer.
Unable to load dynamic library '/xampp/php/ext/php_bz2.dll'
Then follow this steps
just open your current_xampp_containing_drive:\xampp(default_xampp_folder)\php\php.ini in texteditor (like notepad++)
now just find - is the current_xampp_containing_drive:\xampp exist?
if not then find the "extension_dir" and get the drive name(c,d or your desired drive) like.
extension_dir="F:\xampp731\php\ext" (here finded_drive_name_from_the_file is F)
again replace with finded_drive_name_from_the_file:\xampp with current_xampp_containing_drive:\xampp and save.
now again start the composer installation progress, i think your problem will be solved.
What I did was;
1 - I first find out what version of PHP I am using thru the function phpinfo()
<?php
phpinfo();
?>
2 - From there you will find the location of your configuration(php.ini) file
3 - Open that file
4 - Comment out the line similar to the image below
This might be a different value but it should be related to extension.
I am no expert but this process helped me solved similar problem.
In my case I got this error because I downloaded a thread-safe version of the dll (infixed with -ts-), but my installation of php was a non-thread-safe (infixed with -nts-). Downloading the right version of the dll, exactly matching my php installation version fixed the issue.
After Windows 10 XAMPP now I installed LAMPP (XAMPP) on Ubuntu. Windows XAMPP had a lot less to configure compare to MAC (iOS) but now with Linux Ubuntu I had a few more since there are more going in Linux (a good thing).
I confused and activated mysqli.dll (and mysql.dll: erase "#" in /etc/php/7.2/cli/php.ini
I started to get the PHP Warning: PHP Startup: Unable to load dynamic library message related to dll. I commented out mysql(and i).dll in the same file but the message didn't go away up until I commented out " " in /opt/lampp/etc/php.ini.
Looks like XAMPP reads php.ini file from /etc/php/7.2/cli and makes modification in php.ini of /opt/lampp/etc. (;extension=php_pdo_mysql.dll after ";" restarted Apache and no more any message.
I encountered a similar error. The mistake I made was to use the "controller" name as "Pages" instead of "pages" in my url.
In Windows, it could be a wrong path in "System environment variables".
"Path" to the php.exe directory must be the good one.
'C:/PHP/5.2.13/ext\php_mcrypt1.dll'
I'd say there's some typo on your php.ini (the extra 1). Perhaps you're loading a different php.ini from what you expect (see the output of php.ini to make sure).
Other than that make sure that php_mcrypt.dll and PHP:
Were linked to the same VC runtime library (typically msvcrt.dll for VC6 or msvcrt90.dll for VC9) – use e.g. the dependency walker for this
Are both debug builds or both release builds
Both have ZTS enabled or ZTS disabled
For libraries that depend on further libraries (DLLs), make sure they are available (e.g. in the same directory as the extension)
PHP should give you meaning errors if any of the first three conditions above is not satisfied, but I wrote those anyway because I'm not sure for PHP 5.2.
From C:\xampp\php\php.exe I got
Unable to load dynamic library ''
C:\xampp\php\ext\php_.dll (The specified module could not be found.)
I solved by commenting out
C:\xampp\php\php.ini
;extension=
I had the same problem when I tried to use php with sql server, when I added the sqlsrv libraries ... it gave me the error, after several days of researching there, I understood that microsoft does not support x64 in this case so what I did was install laragon x86 and use the corresponding libraries. I hope it helps with something
Go to system env variable and set the php ext dir path as
C:\xampp\php\ext
basically it's finding the ext directory and then locating it's file but it's unable to find the files becuase php path is set as different.

When I attempt to install Laravel 5 I get a dependency error. I'm using Uniform Server on Windows 7. I have enabled php_mbstring.dll and I checked it's loading properly. (I think)
Here is the console output (Composer):
Here are the extensions in my php.ini
Here are the phpinfo() mbstring details:
I don't know where to go from here.
Any idea?
Pay attention that, both in Windows and Linux, PHP can run with multiples php.ini configuration files.
In general, when you find this kind of issue, you have to double check that the configuration file loaded is the same that you are editing or you need to find the right path and add the extension also to the right php.ini configuration file.
While running a script through a web server, you can find the configuration file using the function
phpinfo();
and checking the line "Loaded Configuration File" (or just look for php.ini)
For what concern the CLI you can run in CMD
php --ini
and check the first lines in order to find the Loaded Configuration File value.
I followed the manual, I mpved the php_mongo.dll into the PHP extension folder,
and added extension=php_mongo.dll to the php.ini file and it's given me an error when I try and you rockmango that "To make things right, you must install php_mongo module. Here for installation documents on PHP.net." but I have alread done this any solutions? I am running the lattest version of PHP and mongodb
Check php --ini shows the correct config file being used.
Check php -i (phpinfo) and make sure the module is actually loaded.
Double check you have the right flavour of the module for your version of PHP. (VC6, VC8, VC9, TS, NTS, etc.)
I got my mongo module (1.2.9) for PHP 5.4 32bit on windows from stealth35. It works like a charm.
Often there are multiple PHP locations with different php.ini files.
If you are worried about working in mod_php (through apache) or as a fastcgi then create a file with the following contents.
<?php phpinfo();
Then visit that file in a browser. It will have all the settings and modules listed that are currently being loaded. It will also tell you which php.ini file and modules directory being used.
Please make sure that the ini listed is the one you added mongo dll line.
just getting into php. Trying to get NuSphere remote debugging working. I am coming from VS background so i like that NuSphere is c compiled and not java.
Ok so if you use NuSphere maybe you can help me. I've dumped the dbg-php.5.3.so file in my extensions directory. I've modified my php.ini file:
zend_extension="/usr/local/lib/php/extensions/no-debug-non-zts-20090626/dbg-php-5.3.so"
[debugger]
debugger.enabled=on
debugger.profiler_enabled=on
the file is found.. except when i restart the webserver and run phpinfo (from my user account on a WHM/Cpanel server) the module does not show as being loaded??
I am using the trial version.. not sure if that matters.
This is what I did:
Login to SSH and type php -i | grep php.ini
This will give you the path to the php.ini file you need to edit, on this system it happens to be /usr/local/lib/php.ini (Running CentOS 6 x86_64 with WHM/cPanel).
Edit /usr/local/lib/php.ini and search "extension_dir" which will give you the path to place dbg-php-5.3.so, on this system it happens to be /usr/local/lib/php/extensions/no-debug-non-zts-20090626. Add the .so file there and continue to modify your php.ini file with the debugger options.
To test the the debugger is being loaded I restart httpd "service httpd restart" and then "php -v" to verify the extension loaded properly.
I hope this helps!
