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.

回答2:

sudo apt-get install php5-mcrypt sudo apt-get install php5-mysql 

...etc resolved it for me :)

hope it helps

回答3:

Look /etc/php5/cli/conf.d/ and delete corresponding *.ini files. This error happens when you remove some php packages not so cleanly.

回答4:

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.

回答5:

If you put the ; symbol, this action inactive the extension.

I had the same problem and did the following:

1. Uninstall php with purge parameter:

   sudo apt-get --purge remove php5-common 

2. And install again:

   sudo apt-get install php5 php5-mysql 

回答6:

If you are using 5.6 php,

sudo apt-get install php5.6-curl

回答7:

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 Zend Engine v2.4.0, Copyright (c) 1998-2014 Zend Technologies 

回答8:

My problem was solved by the following command

sudo apt-get install php5-mcrypt 

I have

• PHP 5.3.10-1ubuntu3.4 with Suhosin-Patch (cli)
• Ubuntu Desktop 12.04
• Mysql 5.5

回答9:

Somehow the gmp.so file seems to have been deleted from my system. This is what fixed it for me:

sudo apt-get install --reinstall php5-gmp

回答10:

Try this:

• Open php.ini
• Path: etc/php5/cli/php.ini
• Remove or comment: extension=ssh2.so then save it.

回答11:

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!

回答12:

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 PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php5/20131226/profiler.so' - /usr/lib/php5/20131226/profiler.so: cannot open shared object file: No such file or directory in Unknown on line 0 PHPUnit 5.7.17 by Sebastian Bergmann and contributors. 

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 PHPUnit 5.7.17 by Sebastian Bergmann and contributors. 

i.e. no more warning.
