Even though several other answers suggest it, installing more unnecessary software is generally not the best solution. Instead, you should fix the underlying problem. The reason these messages appear is because you are trying to load those extensions, but they are not installed. So the easy solution is simply to tell PHP to stop trying to load them:
First, find out which files are trying to load the above extensions:
$ grep -Hrv ";" /etc/php5 | grep -E "extension(\s+)?="
Example output for Ubuntu:
/etc/php5/mods-available/gd.ini:extension=gd.so
/etc/php5/mods-available/pdo_sqlite.ini:extension=pdo_sqlite.so
/etc/php5/mods-available/pdo.ini:extension=pdo.so
/etc/php5/mods-available/pdo_mysql.ini:extension=pdo_mysql.so
/etc/php5/mods-available/mysqli.ini:extension=mysqli.so
/etc/php5/mods-available/mysql.ini:extension=mysql.so
/etc/php5/mods-available/curl.ini:extension=curl.so
/etc/php5/mods-available/sqlite3.ini:extension=sqlite3.so
/etc/php5/conf.d/mcrypt.ini:extension=mcrypt.so
/etc/php5/conf.d/imagick.ini:extension=imagick.so
/etc/php5/apache2/php.ini:extension=http.so
Now just find the files that are loading the extensions that are causing the errors and comment out those lines with a ;
. For some reason this happened to me with the default install of Ubuntu, so hopefully this helps someone else.
Seems like you upgraded PHP to newer version and old .ini files are still pointing to old location.
The solution: find out where are modules located now
ls -l /usr/lib/php5
There should be a directory similar to old 20090626
. In my case it is now 20131226
The .ini files giving you an error are located at /etc/php5/cli/conf.d/
Just edit those .ini files which module gives you an error. For example, in case the error is for mcrypt module:
sudo vi /etc/php5/cli/conf.d/20-mcrypt.ini
Change the line:
extension=/usr/lib/php5/20090626/mcrypt.so
to reflect the new path for .so file. In my case the correct path should be:
extension=/usr/lib/php5/20131226/mcrypt.so
That's it! The error is gone. Ofc you'd have to do it with each module giving you an error.
I found this solution by blog.tordeu.com, and it's
sudo aptitude purge php5-suhosin
I'm not sure, but it seems that the suhosin
is no longer needed, it worked for my, my PHP version:
PHP 5.4.34-1+deb.sury.org~lucid+1 (cli) (built: Oct 17 2014 15:26:51)
Copyright (c) 1997-2014 The PHP Group

Well for Ubuntu 14.04 I was getting that error just for mcrypt:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20121212/mcrypt.ini' - /usr/lib/php5/20121212/mcrypt.ini: cannot open shared object file: No such file or directory in Unknown on line 0
If you have a closer look at the error, php is looking for mcrypt.ini and not for mcrypt.so at that location. I just copy mcrypt.so to mcrypt.ini and that's it, the warning is gone and the extension now is properly installed. It might look a bit dirty but it worked!
I had enabled the extension_dir in php.ini by uncommenting,
extension_dir = "ext"
extension=phpchartdir550.dll
and copying phpchartdir550 dll to the extension_dir (/usr/lib/php5/20121212), resulted in the same error.
PHP Warning: PHP Startup: Unable to load dynamic library 'ext/phpchartdir550.dll' - ext/phpchartdir550.dll: cannot open shared object file: No such file or directory in Unknown on line 0
PHP Warning: PHP Startup: Unable to load dynamic library 'ext/pdo.so' - ext/pdo.so: cannot open shared object file: No such file or directory in Unknown on line 0
PHP Warning: PHP Startup: Unable to load dynamic library 'ext/gd.so' - ext/gd.so: cannot open shared object file: No such file or directory in Unknown on line 0
As @Mike pointed out, it is not necessary to install all the stuff when they are not actually required in the application.
The easier way is to provide the full path to the extensions to be loaded after copying the libraries to the correct location.
Copy phpchartdir550.dll to /usr/lib/php5/20121212, which is the extension_dir in my Ubuntu 14.04 (this can be seen using phpinfo()) and then provide full path to the library in php.ini,
; extension=/path/to/extension/msql.so
extension=/usr/lib/php5/20121212/phpchartdir550.dll
restart apache: sudo service apache2 restart
even though other .so's are present in the same directory, only the required ones can be selectively loaded.
I had a similar problem, which led me here:
$ phpunit --version

Unlike the above, installing the software did not resolve my problem because I already had it.
$ sudo apt-get install php5-uprofiler
Reading package lists... Done
Building dependency tree
Reading state information... Done
php5-uprofiler is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 52 not upgraded.
I found my solution via : Debian Bug report logs
$ sudo vim /etc/php5/mods-available/uprofiler.ini
I edited the ini file, changing extension=profiler.so to extension=uprofiler.so .... the result, happily:
$ phpunit --version

i.e. no more warning.
(For Ubuntu users)
I had the same problem, but none of the answers above solved that. Here is how I solved the problem.
Open your php.ini
file (mine was in /etc/php/7.3/cli/php.ini
).
You may have something like this:
extension=pdo_mysql
Or maybe:
extension=/here/is/the/path/to/your/file/pdo_mysql.so
Add the following line before extension=pdo_mysql
extension=pdo
So, you will have:
extension=pdo
extension=pdo_mysql
It seems that the problem is (at least in my case) that we need to load pdo
extension first to load the pdo_mysql
extension.
Hope that helps!
