I've been making upgrades on my Dev workstation using XAMPP for a long time now, from the various version 7s up through 8.012.
I seem to have hit a wall upgrading to 8.1.
I've edited the apache config to use the new version of php. Taking the php.ini-development and renaming it to php.ini, then uncommenting the openssl extension has no effect after I restart apache:
extension=openssl
Openssl isn't enabled in the php info page:
And if I try and enable mongodb by moving my extension over from the previous installation, and uncomment the extension in php.ini and restarting apache again I get an error:
extension=php_mongodb.dll
Update: I now find that enabling ANY PHP module does not work under PHP 8.1.
I can roll back to the previous version of php-8.0.12 and have a fully functioning php again. When I roll back to the previous version enabling and disabling PHP modules still works. It does not work under PHP 8.1.
I'd like to stay up to date with the latest release if at all possible!
What am I doing wrong with this version of PHP? Why can't I enable anything?
I've had to set the FULL PATH to the extensions directory on Windows. Once I did that and restarted, I was able to enable / disable extensions. Look for this line in php.ini and adjust it to your needs:
; On windows:
extension_dir = "C:\xampp\php-8.1.0\ext\"
This setting only seems important on Windows. Set that line the way you want it, restart apache and you should be good to go!
You are copying an incompatible module compiled with the older version. If you are upgrading the PHP version, You'll need an extension DLL file compiled with that specific version of PHP and suitable for your server environment. You can download the compatible packages from here PECL. Download and put the .dll file in your extension directory. Then, you'll need to enable that extension.
Here is the guide for the windows system Installing a PHP extension on Windows.
For MongoDB, get it here https://pecl.php.net/package/mongodb
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.
I'm beginer with Symfony2 Framework and php. I have started doing a SF2 tutorial and i stopped on setting up the project. I can't install Composer from SF official page on Windows 8, when i choose a php.exe from my php file and click install, then i see following error:
Some settings on your machine make Composer unable to work properly.
Make sure that you fix the issues listed below and run this script again:
The openssl extension is missing, which means that secure HTTPS transfers are impossible.
If possible you should enable it or recompile php with --with-openssl
I'm working with WebServ 2.1. I have added to php.ini DEVELOPMENT following code
extension_dir = C:\WebServ\php\ext
extension=php_openssl.dll
C:\WebServ\php\ext is a path to folder with extension files and it contain php_openssl.dll.
It still doesn't work. Do anybody knows how to fix it?
Print phpinfo() and make sure SSL is present there.
Don't forget to restart the webserver after editing php.ini
Was trying to play with symfony2. If I hit the web/config.php of my symfony2 installation it shows me the following problems
Install and enable the mbstring extension.
Install and enable the intl extension (used for validators).
Install and enable a PHP accelerator like APC (highly recommended).
Install PDO drivers (mandatory for Doctrine).
I can understand that these are not mandatory ones but question is I fixed these in my php.ini file but still cant see any reflection in this page. Here is how I fixed the above problems
extension=php_intl.dll
extension=php_mbstring.dll
extension=php_pdo_mysql.dll
Didnt install anything for APC so no complain with that. Restarted apache server "thousand" times, but no luck.
Side Note:
I tried to figure out something from phpinfo(). I can see one discrepancy. The phpinfo is showing one of my old php directory path F:\Softwares\Development\PHP\php-5.5.13-x64. This path used to exist in my system PATH variable earlier. But I myself remove this location from System PATH variable. But it is still visible in phpinfo(). But if I print the PATH variable from command prompt or cygwin console, it shows the correct PATH variable.
Also ran php app/check.php. It shows everything OK except the APC, which is completely fine for me. But it also shows that "PHP CLI can use a different php.ini file than the one used with your web server".
Environment Details:
OS: Windows 7
php: php-5.4.30-Win32-VC9-x86
Apache: Win32-2.4.9 VC9
MySQL: mysql-5.6.19-winx64
Not using any xampp/wampp etc.
Few more hear left on my head. Please help.
Make sure that you have these extensions in your ext directory, if not search and put it in the directory (for windows extension file type must be .dll).
APC https://www.dropbox.com/s/hmnrgle8xing3fo/php_apc.dll
INTL https://www.dropbox.com/s/wm14zk0grc6pm6v/php_intl.dll (you also need ICU lib)
mbstring https://www.dropbox.com/s/wm14zk0grc6pm6v/php_intl.dll
PDO mysql https://www.dropbox.com/s/hd5cm02oti8qw3s/php_pdo_mysql.dll
Also, don't forget to restart apache after changes in php.ini
I'm trying to install XDebug on my local machine with Win 7, Apache 2, PHP 5.3.6 TS VC9 build (server manually installed, no package). I've followed instructions at http://xdebug.org/find-binary.php:
I've downloaded dll, moved to dir with other extensions, added following code to C:\Windows\php.ini, restarted server and - in contrary to my expectations - xdebug is neither installed nor listed in phpinfo page.
zend_extension="E:\www\server\php\ext\php_xdebug-2.1.2-5.3-vc9.dll"
Altough I've gone trough my phpinfo and XDebug site several times I still have no idea what can cause this problem. Do you have any suggestions how to get XDebug working please?
Thank you
According to netbeans manual you have to add the xdebug configuration file to the apache php ini directory and not the local php ini directory to make it work with anykind of wamp.
1) http://wiki.netbeans.org/HowToConfigureXDebug
2) Definition of wamp: http://en.wikipedia.org/wiki/WAMP
try zend_extension**_ts**=...
and the in a console fire php -m to see whats in. No need to restart server
I "solved" the problem by updating from 5.3.6 to 5.3.8. I dont know where the problem was, but update and it will work fine. (I used http://xdebug.org/find-binary.php)
