I have ubuntu 14.04 EC2 instance. I have installed php 7 on it. when I execute any php command like php --version or any other. I get following error
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/php_mysqli.dll' - /usr/lib/php/20151012/php_mysqli.dll: cannot open shared object file: No such file or directory in Unknown on line 0
I have tried following
enable php_mysqli.dll in php.ini
enable mysqli.so
enable php_mysqli.so
sudo apt-get install php-mysql
but nothing worked for me.
Any suggestion how I can solve this?
If you are on Linux, you shouldn't have DLL files but SO files.
So first, you have to remove / disable the php_mysqli.dll you added in php.ini.
In order to use mysqli, you should then :
install the package for Ubuntu : apt-get install php-mysql
check if it is already enabled (with phpinfo() for example)
if not enabled, enable the module - check in /etc/php/mods-available/ folder if there is a mysqli.ini, containing extension=mysqli.so, then check for CLI / FPM / Apache / other if there is the symbolic link pointing to this file (for example for CLI, in /etc/php/cli/conf.d/ : 20-mysqli.ini -> ../../mods-available/mysqli.ini)
restart php / apache / nginx depending what you are using
In my case, it happened because I uncommented the extension=php_mysqli.dll line in php.ini file for running some other package. After Googling around I found that you should not uncomment anything directly from php.ini instead you should install the required PHP extension and it will do the rest.
I have recently encountered this problem on ubuntu16.04, I finally resolve it by adding a semi-colon at each line like extension=php_*.dll,I think that is because LAMP on ubuntu is intelligent enough，it automatically opens all of the extensions for us. And on windows,we have to enable the extensions manually by remove the semi-colon at each line like ;extension=php_*.dll in php.ini.
Run Phpinfo()
Search for your php.ini path
search extension=php_mysqli.so
comment like this
;extension=php_mysqli.so
If you are on Linux and using php8.1,
try to commenting extension=pdo_mysql in directory /etc/php/8.1/cli/php.ini file if the extension is uncommenting
uncommenting extension=pdo_mysql in directory
/etc/php/8.1/apache2/php.ini file if the extension is commenting
this method work for me
I just had the same problem and realised they were two folders in my /etc/php/7.0, which were apache2 and cli. Turned out the extension line in cli/php.ini was uncommented with the dll file, not the one in apache2 directory. Commenting it just solved the problem.
I managed to solved it like this:
add libs to php.ini (etc/php/7.3/apache2; etc/php/7.3/cli folders)
extension=pdo_mysql.so
restart apache (sudo systemctl restart apache2)
comment libs in php.ini (etc/php/7.3/apache2; etc/php/7.3/cli folder)
extension=pdo_mysql.so
go etc/php/7.3/mod_available
comment extension (because it is already loaded), for example, etc/php/7.3/mod_available/pdo_mysql.ini
;extension=pdo_mysql.so
If you see mcrypt.so under /etc/php/7.2 or /etc/php/7.3 just delete it and restart the server it will resolve the issue.
As when we updrage the php to latest version that file may get stored to latest versions which is not required.
I used following commands:
cd /etc/php/7.3
sudo rm -rf mcrypt.so
sudo service apache2 restart
Just comment out all lines with .dll extensions because you are on Ubuntu. Ubuntu support .so files.
In php.ini under Dynamic Extensions the line extension=php_mysqli.dll was enabled.
I disabled it by adding a semi-colon at the head of the line ;extension=php_mysqli.dll.
Saved and exited php.ini. Restarted Apache.
This resolved the error for me.
Whenever I try to enter my phpMyAdmin, it gives me this error:
The mbstring extension is missing. Please check your PHP configuration.
I've looked all over the Internet for a fix, but all I've found is errors similar to mine, but not the same, or the exact same but there was no fix given.
I am also using Windows.
In Centos I have installed a php extension.
I did this with:
yum install php-mbstring
Before sometime I also had the same problem. I have tried replacing the .dll file but no result. After some debugging I found the solution.
I had this in my php.ini file:
extension_dir = "ext"
And I'm getting mbstring extension missing error. So I tried putting the full path for the extension directory and it works for me. like:
extension_dir = "C:\php\ext"
Hope this will help.
Cheers,
check your php.ini file in the root directory of your php installation. In the extensions part of the configuration you should find:
;extension=php_mbstring.dll
remove the leading ';' to uncomment and enable the extension so it looks like this:
extension=php_mbstring.dll
restart your apache and it should work.
Edit: I just read that you are already using a webhost. Does your webhost have a interface where you can set php variables etc? Or a .ini file you can edit?
If not you may are forced to talk to the webhost and ask them to enable that particular extension.
My case was like this
Strangely, I noticed that the php.ini file that WAMP was using wasn't
the one in the php directory, but rather was referencing a php.ini
file in the bin directory... I copied my php.ini file to
wamp\bin\apache\apache2.4.17\bin directory, restarted the wamp
services and PHPMyadmin was off and running...
Thanks I solved the problem
In Ubuntu Server I have installed a php extension.
I did this with:
sudo apt-get install php-mbstring
Another reason for this problem is Php version. When I changed the running PHP version to 7.0.0, problem has gone.
Ubuntu 15.10
1) sudo nano /etc/php/7.0/apache2/php.ini
uncommited extension=php_mbstring.dll
2) sudo apt-get install php7.0-mbstring
3) restart apache2
install mbstring and restart your apache:
sudo apt-get install php-mbstring
sudo service apache restart
then remove ; from your php.ini file:
;extension=php_mbstring.dll
to
extension=php_mbstring.dll
If it still doesn't work..remove your php setup, without removing the databases from your phpmyadmin. Reinstall it.
NB: * if you want to remove all, all mention the one you need to.
sudo apt-get remove php*
Then install the php and modules of the php version that you need. here, php 7.1:
sudo apt-get install php7.1 php7.1-cli php7.1-common libapache2-mod-php7.1 php7.1-mysql php7.1-fpm php7.1-curl php7.1-gd php7.1-bz2 php7.1-mcrypt php7.1-json php7.1-tidy php7.1-mbstring php-redis php-memcached
restart your apache and check the php version.
sudo service apache restart
php -v
when all this is done, execute the following command to enable mbstring forcefully and restart your apache.
sudo phpenmod mbstring
sudo service apache restart
Hope it helps.
It did to me :)
I've solved my problem by this way:
Edit the php.ini file:
change extension_dir = "ext" into extension_dir = "D:\php\ext" （please write ur own full path for the extension directory）
change ;extension=php_mbstring.dll into extension=php_mbstring.dll （delete the ";"）
Then just save your php.ini file and copy it to ur Windows directory。(“C:\Windows“)
restart the apache server。
The above is my solution,Hope it will work for u.
Using xampp, this will work (php7 has been extracted to the xampp\php directory):
Make the following changes in the php.ini:
uncommend (remove the ;)
;extension=php_mbstring.dll
uncommend (remove the ;)
;extension=php_mysqli.dll
set the path to the extention Directory
extension_dir = "ext"
to the full path, for example:
extension_dir = "C:\xammp\php\ext"
Additional, change the xampp-settings in the httpd-xampp.conf:
change
LoadFile "C:/xampp/php/php5ts.dll"
to
LoadFile "C:/xampp/php/php7ts.dll"
change
LoadModule php5_module "C:/xampp/php/php5apache2_4.dll"
to
LoadModule php7_module "C:/xampp/php/php7apache2_4.dll"
change all appearance (3 times) of
IfModule php5_module
to
IfModule php7_module
That's it.
I had this problem in the past with MAMP on a Windows machine.
Open MAMP start page and go to your current configuration of PHP (phpinfo).
Check the Configuration File (php.ini) PATH.
Mine was set to C:\Windows, where of course I had no PHP.ini file.
Either change the php.ini path to C:\MAMP\conf\php5.6.8 (or your php version conf path) or just copy php.ini to c:\windows.
after installing WAMP 3 with Apache 2.4.17 and php5.6.17 I tried to look at php.ini from wampserver (green icon in tray).
It wasn't finding it.
I copied php.ini from the php.5.6.15 directory to the apache2.4.17\bin\ directory
and phpmyadmin worked fine without missing mbstring
Solved it.
I tried all of the solutions above but it still did not work. I'm currently using WAMP to launch the mysql server. When I tried to open the "php.ini" file with the WAMP panel, it said that it did not exist and asked me to create a new "php.ini" in the location, "C:\wamp\bin\apache\apache2.4.17\bin". Once I created this new "php.ini" file, I located the existing "php.ini" file which was in the path "C:\wamp\bin\php\php5.6.15", and cloned it. I then pasted the clone in the previous path where it had asked me to create the "php.ini" file.
Hope this helped.
I just installed WAMP 3 on Windows 10 and had this issue.
I had to go to C:\wamp64\bin\php\php7.0.0\ and copy the php.ini file to C:\wamp64\bin\apache\apache2.4.17\bin\
Then I restarted WAMP, and was finally able to access my phpMyAdmin file.
Note: this is probably not the correct way to do this because now there are 2 php.ini files. There is probably a setting in an Apache file that points to the php.ini file, but I haven't seen that yet. I will update this if I find it.
Strangely, I noticed that the php.ini file that WAMP was using wasn't the one in the php directory, but rather was referencing a php.ini file in the bin directory... I copied my php.ini file to wamp\bin\apache\apache2.4.17\bin directory, restarted the wamp services and PHPMyadmin was off and running...
In newer versions of PHP, "extension_dir" is not initially enabled.
In php's directory try change extension of configuration file (php.ini-development - default value of this file). I changed it to php.ini and phpmyadmin has worked.
The program can't start because php_mbstring.dll is missing from your computer. Try to fix it.
i use appserver to localhost and my server: C:/AppServ/www/dvd2/variables.php
Mozilla/5.0 (Windows NT 6.1; rv:33.0) Gecko/20100101 Firefox/33.0
Apache/2.2.8 (Win32) PHP/5.2.6
To solve this problem on Linux, you need to recompile your PHP with the --enable-mbstring flag.
You might get this error message if you've just installed the phpmyadmin package but haven't restarted apache yet; try restarting apache.
Please uncomment the following lines at php.ini
;extension=php_mbstring.dll
;extension=php_exif.dll ; Must be after mbstring as it depends on it
;extension=php_mysql.dll
;extension=php_mysqli.dll
This will help to solve.
The version of phpadmin you have installed is not compatible with the version of apache. Install the compatible version and you should be fine
I recently updated from PHP 5.4.44 to PHP 5.6.12 on my Windows 8.1 OS and got this phpMyAdmin missing mbstring error message.
After trying the above suggestions, none of which worked for me, I discovered version 5.4.44 placed the DLL extensions in the PHP root directory whereas version 5.6.12 placed them in the PHP\ext subdirectory.
All very fine except unfortunately someone forgot to change the php.ini accordingly. So two possible solutions:
Copy the DLL extensions from the ext sub-directory into the PHP root directory, or
Edit the php.ini file to call all the DLL extensions from the ext sub-directory.
I chose the easier first and phpMyAdmin now works fine.
Depending on you OS, you might need to install additional packets, e.g. php5-mbstring in SLES Linux.
I check phpinfo() and look for this line:
Configuration File (php.ini) Path C:\Windows
And I copy php.ini from C:\xampp\php to the folder and it works for me.
I had the same problem, the above solutions are not worked for me.
What I did is uninstalled the wamp and logout the Skype and re-installed wamp.
Then It got worked. I think the port used by wamp and Skype is same.
Hope this input will help.
Cheers :)
my solution : Copy a shortcut from your php.ini from your php-directory to the apache-dir. This way you refere too 1 file on the correct place. This solved (at least in my case) the problem.
just copy the php.ini file from C:\wamp\bin\apache\apache2.4.17\bin to C:\wamp\bin\apache\apache2.4.17\bin and then again restart apache server..
it will work fine.
My solution:
I had wamp x32 installed before, needed to remove and then installed the x64, receiving the same message "The mbstring extension is missing. Please check your PHP configuration.".
On php.ini, all references to wamp, such as extension_dir = were pointing to "C:/Program Files/Wamp/...". Check all paths, the correct for me is "C:/Wamp64/". Restart services and it's all right now.
The installation process adds the phpMyAdmin Apache configuration file into the /etc/apache2/conf-enabled/ directory, where it is read automatically. The only thing you need to do is explicitly enable the mbstring PHP extension, Because sometimes you forgot to enable the mbstring mode so simply type the below command to enabled the mbstring mode...
sudo phpenmod mbstring
Afterward, restart Apache for your changes to be recognized:
sudo systemctl restart apache2
I'm running a local server on my macbook (os x 10.9.2)
I'm trying to install mcrypt and I've run into a problem that I can't add the extension to my php.ini file, because apparently my php installation doesn't use a php.ini file.
Looking at phpinfo(), I see this:
Configuration File (php.ini) Path: /etc
Loaded Configuration File: (none)
In my /etc folder, a php.ini file doesn't exist. I do have a php.ini.default, but when I make a copy of that and name it php.ini, and restart apache, PHP just stops working entirely (my php code isn't interpreted and shows up when viewing the web site's source).
Is there something in the php.ini.default file I have to change before copying it to php.ini?
Edit: Upon further trial and error, I have found that if I create a blank php.ini file and restart the server, PHP runs just fine. There must be an error in php.ini.default that is killing PHP on my local server. I've tried using php.ini.default~orig too and the same problem happens. Any way to find out what is wrong with the php.ini.default file?
Edit2: Upon further random trial and error, if my php.ini only contains:
[PHP]
short_open_tag = On
PHP works. If it only contains:
[PHP]
short_open_tag = Off
PHP doesn't work. I'm so confused.
Edit3: Oh! The php.ini.default file had short_open_tag = Off, and of course I'm using short open tags everywhere. Edit2 clued me in. Wasted half a day on this. This is so embarrassing. Everything is working now.
In case someone else runs into the missing php.ini problem on OS X 10.9 or 10.10:
I ran into the same problem after trying install the latest php through homebrew. Turns out mac comes with php already installed, but no config file. Homebrew won't overwrite the system php binary, which remains the default.
Try sudo rm /usr/bin/php then brew install homebrew/php/php55.
I recently moved my website to a nginx server. My python code is running on the same machine on 8086 port, but my php curl module is not working. I don't know what I am doing wrong here.
I already installed php5-fpm, but stil not able to resolve this issue. I can not see the error also because nginx simply shows me the blank screen. Btw. it is printing all the values before curl_init() statement.
I can post my Nginx configuration also but i don't think so that is required.
You need to run /etc/init.d/php5-fpm restart
If you are on Windows, make sure to follow the below steps:
Rename php.ini-production or php.ini-development to php.ini
Specify the extension directory: extension_dir = "ext"
Enable the Curl extension (Uncomment in php.ini): extension=php_curl.dll
