Not sure what happened, but below is what the log is giving me when trying to access phpmyadmin, please help. Trying to debug a different problem and ran into this. Not really possible to revert back to when it was working.
PHP Fatal error: Call to undefined function mb_detect_encoding() in
/usr/share/php/gettext/gettext.inc on line 177
When trying to go the the site, I get this error, I think it's likely the two errors are related:
Database connection error (1): The MySQL adapter 'mysqli' is not available.
First error is caused by php because the extension mbstring is either not installed or not active.
The second error is output of phpMyAdmin/your site asking you to install / enable the mysqli extension.
To enable mbstring and mysqli edit your php.ini and add/uncomment the two lines with mbstring.so and mysqli.so on unix or mbstring.dll and mysqli.dll on windows
Unix /etc/(phpX/)php.ini
extension=mysqli.so
extension=mbstring.so
Windows PHP installation folder\etc\php.ini
extension=mysqli.dll
extension=mbstring.dll
Don't forget to restart your webserver after this.
EDIT:
User added he was using redhat in the comments so here's how you install extensions on all CentOS/Fedora/RedHat/Yum based linux distros
sudo yum install php-mysqli
sudo yum install php-mbstring
restart your werbserver
sudo /etc/init.d/httpd restart
you can verify your installation with a little php script in your document root.
This lists all settings, versions and active extensions you've installed for php
test.php
<?php
phpinfo();
After reading about the extension_dir = "ext" i added the line to php.ini but didnt work, then started to look apache error log and saw the PHP was in fact unable to find the dll's in the specified directory "ext". I commented the extension_dir line, restarted Apache and looked the error log again, saw that PHP was now looking the dll's in C:/PHP/ext (by default i guess), but since im using other folders, that's not the correct path, so i uncommented the extension_dir line and wrote this:
extension_dir = "C:/Apache24/PHP/ext"
In my configuration that is the correct path to dll's.
and of course, uncommented:
extension=php_mbstring.dll
extension=php_mysql.dll
extension=php_mysqli.dll
Restarted the Apache server and internet browser and now phpMyAdmin works with my mySQL login.
So, dll's incorrect path and dll's needed commented in php.ini were the problem.
Remember to restart Apache and internet browser after editing config files.
System spec:

Hope this help. Thx for your comments too.
in ubuntu 16.04 when i tried to connect to phpmyadmin a white blank paged appeared so i ran the above command and phpmyadmin works
sudo apt-get install php-mbstring php7.0-mbstring php-gettext
for mysql support install
sudo apt-get install php7.0-mysql
tested in ubuntu 16.04 with php 7 version
It looks like your PHP installation does not have the mbstring extension and the mysqli adapter extension installed.
Please check your phpinfo(); or run php -i | grep 'mbstring\|mysqli' in a terminal.
I had the same problem on my windows7- 32 bit:
1."PHP Fatal error: Call to undefined function mb_detect_encoding() in /usr/share/php/gettext/gettext.inc on line 177"
when i opened my php.ini file , "extension_dir" line looked like following :
extension_dir = "C:/wamp/bin/php/php5.4.16/ext/"
which i changed to :
extension_dir = "C:\wamp\bin\php\php5.4.16\ext\"
and it worked.
In php.ini, I had to change
extension_dir = "ext"
to
extension_dir = "C:/PHP/ext"
as my PHP was installed in C:\PHP. I had to use / instead of \, and then it worked.
Also uncomment mbstrings, mysqli and mysql extensions.
What helped me (using XAMPP on Windows) was to:
make sure that my path included the correct path for PHP (I had two PHP
installations, one under c:\php and the XAMPP installation in
c:\xampp\php which was the one I wanted to use)
check that the lines
extension_dir="C:\xampp\php\ext" extension=php_mbstring.dll extension=php_exif.dll ; Must be after mbstring as it depends on it were uncommented in the php.ini file (i.e. no ; at the beginning)
restart the Apache server
last but not least, clear the cache when reloading the page http://localhost/phpmyadmin/ (for instance with Ctrl-F5 in Chrome)
Recompile PHP with mbstring.
./configure --enable-http --with-apxs2 --with-mysql --with-gd
--with-curl --with-mbstring
make
make install
My guess would be to check that the mysqli extension is enabled in your PHP configuration. More info would be great (eg. OS, AMP stack, etc.).
Check in your php.ini configuration for mysqli and make sure there is no ';' in front of the extension. The one enabled on my setup is php_mysqli_libmysql.dll.
Try to install mysqli and pdo.
Put it in terminal:
./configure --with-mysql=/usr/bin/mysql_config \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd
I tried on Windows and I was getting same issue after enabling this in PHP installation folder\etc\php.ini:
extension=mysqli.dll
extension=mbstring.dl
You should also enable the following in the ini file:
extension_dir = "ext"
phpMyadmin is working now!
In windows 2008 Server.
i removed ";" in front of extension=php_mbstring.dll in php.ini file and it worked... i followed below link...
https://bugs.php.net/bug.php?id=64965
Some versions of windows do not come with libmysql.dll which is necessary to load the mysql and mysqli extensions. Check if it is available in C:/Windows/System32 (windows 7, 32 bits). If not, you can download it DLL-files.com and install it under C:/Windows/System32.
If this persists, check your apache log files and resort to a solution above which responds to the error logged by your server.
One options is:
disabled this extension_dir = "ext"
and the other is:
go to wamp icon and see php and the click on php error logs then from error log u can find exact error.
this error occurs only if paths are not properly set.
I had the same trouble, this is what worked for me.
You can click at the wampserver icon, then at the PHP error log.
Check if it says this:
Unable to load dynamic library 'c:/wamp/bin/php/php5.5.12/ext/php_ldap.dll'
If yes, then you can reload your version of PHP, by clicking at the wampserver icon, then PHP, then version, and then you click at your version.
Wait for everything to be online again, then try to access phpmyadmin.

I receive this error after trying to set up LAMP by following this tutorial, and I find myself receiving the above error after trying to set up phpmyadmin.
Fatal error: Call to undefined function mb_detect_encoding() in
C:\WebServer\Apache\htdocs\phpmyadmin\libraries\php-gettext\gettext.inc
on line 177
I followed the advice over here: PHP Fatal error when trying to access phpmyadmin mb_detect_encoding, and made those changes.
When I run phpinfo(), I see that support for MySQL and mb_string are enabled as shown below:
Install the gd library also.
check this link
http://www.php.net/manual/en/mbstring.installation.php
There's a much easier way than recompiling PHP. Just yum install the required mbstring library:
Example: How to install PHP mbstring on CentOS 6.2
yum --enablerepo=remi install php-mbstring
Oh, and don't forget to restart apache afterward.
Mbstring is a non-default extension. This means it is not enabled by default. You must explicitly enable the module with the configure option.
In case your php version is 7.2:
sudo apt-get install php7.2-mbstring
sudo service apache2 restart
In case your php version is 7.0:
sudo apt-get install php7.0-mbstring
sudo service apache2 restart
In case your php version is 5.6:
sudo apt-get install php5.6-mbstring
sudo service apache2 restart
On Windows open the file php.ini and make this changes:
Remove the comment and point to the ext directory
; extension_dir = "./" -> extension_dir = "C:/Php/ext"
Remove the comment of this extensions
extension=php_mbstring.dll
extension=php_mysqli.dll
Restart apache service
httpd -k restart
When I opened my php.ini file, "extension_dir" line looked like following :
extension_dir = "C:/wamp/bin/php/php5.4.16/ext/"
which i changed to:
extension_dir = "C:\wamp\bin\php\php5.4.16\ext\"
and it worked.
Under Windows / WAMP there doesn't seem to be any php_mbstring.dll dependencies on the GD2 extension, the MySQL extensions, nor on external dlls/libs:
deplister.exe ext\php_mbstring.dll
php5ts.dll,OK
MSVCR110.dll,OK
KERNEL32.dll,OK
deplister.exe ext\php_gd2.dll
php5ts.dll,OK
USER32.dll,OK
GDI32.dll,OK
KERNEL32.dll,OK
MSVCR110.dll,OK
Whatever php_mbstring already needs, it's built-in (statically compiled right into the DLL).
Call to undefined function mb_detect_encoding()
This error is also very specific and deterministic...
The function mb_detect_encoding() didn't fail because php_gd, php_mysql, php_mysqli, or another extension was not loaded; it simply was NOT found.
I'm guessing that all the answers that are reported as valid (for Windows / WAMP), that say to load other extensions, to change php.ini extension_dir paths (if this one was wrong to begin with, NO extensions would load), etc, work more due to a) un-commenting the extension = php_mbstring.dll line, or b) restarting Apache or the computer (for changes to take effect).
On Windows, most of the time the problem is that php_mbstring.dll is either:
Blocked by Windows. Unblock it by right-clicking it, check Properties.
Or PHP can't load php_mbstring.dll due to another version getting loaded (e.g., from some improper PHP DLLs install into C:\Windows\system32), some version mismatch, missing run-time DLLs, etc. Check Apache's and PHP's error log files first for clues.
More in-depth answer here: Call to undefined function mb_detect_encoding
For fedora/centos/redhat:
yum install php-mbstring
Then restart apache
you should use only english version of phpmyadmin if you are using all languages you should enable all languages mbstring in php.in file.....just search for mbstring in php.in
The problem could also be that Apache can't find php.ini
If you set PHPIniDir incorrectly.
Mine was set to: PHPIniDir "c:/php7"
But, the folder is actually just "php"
The clue was viewing phpinfo()
Which showed:
Configuration File (php.ini) Path C:\windows
I had the same problem with Ubuntu 17, Ispconfig was not processing the operations queued of any kind and also the server.sh command was not working.
I checked and the running PHP version after the OS upgrade was 7.1 so the solution was to type:
apt-get install php7.1-mbstring
and now is everything ok
Hope this helps some ppl, I got this error when i added the path and extension to "docref_root" "docref_ext" in my php.ini file, I then commented it out and it was ok, but cant get my help to work now.
In case your php version is 7.2:

pdo is working fine with mysql but with pgsql its giving error 'PDOException' with message 'could not find driver' I've installed php5-pgsql package which also includes pdo_pgsql
http://packages.debian.org/sid/php5-pgsql
This package provides a module for PostgreSQL database connections directly from PHP scripts. It also includes the pdo_pgsql module for use with the PHP Data Object extension.
my dsn is pgsql:dbname=DB;host=192.168.0.2
I am using Ubuntu 10.04
This message means you need to install and or activate postgresql extension in PHP
This solution works for me :
To install postgresql extension
[sudo] apt-get install php-pgsql
after, for activating it, uncomment pgsql and pdo-pgsql extensions in etc/php/$PHP_VERSION/apache2/php.ini file
Finally, type :
[sudo] /etc/init.d/apache2 restart
To restart apache server if you use apache such as was my case...
1) Have you enabled pgsql.so in php.ini (extension=pgsql.so)?
2) Is you Postgresql listenin on 192.168.0.2 interface? (You can check it by netstat -tpln)
3) How you authenticate your access into Postgresql?
Make sure you've uncommented the line that tells php where the Postgres driver is (usually extension=pgsql.so) in the main php.ini file.
I had the same issue. First of all - check is it enabled in php.ini. Uncomment extension=php_pdo_pgsql...
than set up extension directory!!
extension_dir = "ext" ; for your case it could be other dir.
and do not forget to restart server after changing the config.
Try to remove semicolon in front of
extension=pgsql
extension=pgsql.so
included in your php.ini file
You can do that from the XAMPP Control Panel.
Here is what I did to solve the problem.
Edit php.ini and remove ; from extension=pdo_pgsql. Also, add extension=pgsql.so to the php.ini file.
Make sure to restart the Apache server before you try to see the result.
I had the same problem with another solution. I lost my around 4 hours to solve this problem. Please check the following to solve this problem.
Check php.ini file and remove semicolon from this line
extension=pgsql
extension=pdo_pgsql
Restart your apache2 server
sudo service apache2 restart
Check if your PDO driver has updated in localhost phpinfo()
I did All the things right and still I had this problem. And you know why? Because I had several versions of php installed. So I was running php7.4 in my php cli but localhost was running on php7.2. So always check your php versions.
Check your php version on localhost and terminal cli
When you do not have postgresql installed on the same machine that is Apache and PHP; you have to install php-pgsql and don't have to add extensions in php.ini manually in Linux (in Windows yes), because redundancies are generated and this does not work (checked in error.log).
$ sudo apt install php-pgsql
Then you can check the existence of the extension enabled automatically in:
$ sudo nano /etc/php/7.0/apache2/conf.d/10-pdo.ini
Observations: In phpinfo() you will find the directory conf.d/ and the file error.log
GL
Just run php --ini and look for Loaded Configuration File in output for the location of php.ini used by your CLI
then check you have enabled the extensions correctly.
Copy libpq.dll from the PHP directory to Apache24\bin (or wherever your installation could be).
I am trying to connect to my database (remote server) which has PostgreSQL installed in it. My PHP code is trying to connect to the database using pg_connect(), but I get the error saying:- "Fatal error: Call to undefined function pg_connect() in /var/www/website/functions.php on line 82".
The line 82 simply is:
$db = pg_connect($conn_string);
where $conn_string = "host=".$hostname." port=5432 dbname=".$dbname." user=".$db_user." password=".$db_password.""
(all variables defined earlier)
I checked many forums and the only solution suggested was locating the php.ini file which contains a line:- extension = pgsql.so (for UNIX) and extension = php_pgsql.dll (for Windows).
This statement is supposed to be commented and the solution is to uncomment it. I have tried it but still does not change the situation. The remote server has a version later than PostgreSQL v9.0.4 installed.
I then installed PostgreSQL v8.4.8 on to my laptop and ran the website locally using MAMP. At first, Apache crashed for some odd reason, I fixed that problem but again I ended up with the same error as before i.e. Fatal error: Call to undefined function pg_connect()....
I also ran the phpinfo() and it showed that the php version does support the PostgreSQL module.I have spent an entire day searching for the solution but have been unsuccessful. This is my first project developing a website and I am out of wits. Any kinda help will be highly appreciated.
phpinfo() gives me a huge list of things at the terminal but the listings relevant to PostgreSQL are as follows:-
pdo_pgsql
PDO Driver for PostgreSQL => enabled
PostgreSQL(libpq) Version => 9.0.4
Module version => 1.0.2
Revision => $Id: pdo_pgsql.c 306939 2011-01-01 02:19:59Z felipe $
pgsql
PostgreSQL Support => enabled
PostgreSQL(libpq) Version => 9.0.4
Multibyte character support => enabled
SSL support => enabled
Active Persistent Links => 0
Active Links => 0
Directive => Local Value => Master Value
pgsql.allow_persistent => On => On
pgsql.auto_reset_persistent => Off => Off
pgsql.ignore_notice => Off => Off
pgsql.log_notice => Off => Off
pgsql.max_links => Unlimited => Unlimited
pgsql.max_persistent => Unlimited => Unlimited
I had restarted MAMP after every edit I made since it was mentioned in every post I have read so far. I believe that resets both Apache and php.
'pqsql.so' (which is the UNIX equivalent of 'php_pqsql.dll' in Windows) is present in the 'extension' directory. I also copy-pasted the 'pqsql.so' file on to the Apache/bin directory but it did not give me any change.
I am not running php in the command line primarily. I just was curious to see what phpinfo() would give me relevant to pgsql which I have mentioned in my reply above.
I am still working on the tools you have mentioned and will respond as soon as I get any results.
Thanks,
H
You need to install the php-pgsql package or whatever it's called for your platform. Which I don't think you said by the way.
On Ubuntu and Debian:
sudo apt-get install php-pgsql
Easy install for ubuntu:
Just run:
sudo apt-get install php5-pgsql
then
sudo service apache2 restart //restart apache
or
Uncomment the following in php.ini by removing the ;
;extension=php_pgsql.dll
then restart apache
Fatal error: Call to undefined function pg_connect()...
I had this error when I was installing Lampp or xampp in Archlinux,
The solution was edit the php.ini, it is located in /opt/lampp/etc/php.ini
then find this line and uncomment
extension="pgsql.so"
then restart the server apache with xampp and test...
Edit. I just noticed you were mentionning MAMP. My advice is for Windows but may be useful if you know what corresponding tools to use.
Things to try:
Have you restarted PHP and Apache since your editing of php.ini?
Is the php_pgsql.dll found in your php\ext directory?
Are you running php as a module? If so, try copying the php_pgsql.dll
file in the Apache\bin directory.
Are you running PHP from the command line with a flag specifying a
different php.ini file?
You could try using a tool such as Sysinternals' Filemon to view what
files are attempting to be accessed when running PHP.
You could try using a tool such as Dependency Walker to look at the dependencies for the postgreSQL DLL, in case you have a missing dependency. Quick search brought up ldd for Unix.
Add 'PHPIniDir "C:/php"' into the httpd.conf file.(provided
you have your PHP saved in C:, or else give the location where PHP
is saved.)
Uncomment following 'extension=php_pgsql.dll' in
php.ini file
Uncomment ';extension_dir = "ext"' in php.ini
directory
I had the same symptom in win7. I got this script:
<?php
phpinfo();
pg_connect("blah");
When I executed the phpinfo.php script via apache (http://localhost/phpinfo.php) then I got the error message:
Call to undefined function pg_connect() in...
When I executed the same script from command line (php phpinfo.php) then I got the expected message:
PHP Warning: pg_connect(): Unable to connect to PostgreSQL server: missing "=" after "blah"
In both cases the expected php.ini was used:
Loaded Configuration File C:\Program Files (x86)\php\php.ini
but the pgsql section was completely missing from the phpinfo in case of the apache-based execution and it was present in the command-line-based execution.
The solution was that I added the following line to the apache httpd.conf:
LoadFile "C:/Program Files (x86)/php/libpq.dll"
It seems that for some reason this file is not loaded automatically when apache runs the php script but it is loaded if I run the php script from the command line.
I hope it helps.
You have to follow these steps:
Open the php configuration file, which is located in the following directory
C: \ xampp \ php \ php.ini
Within that file search the extension section and uncomment the following lines
extension = php_pdo_pgsql.dll
extension = php_pgsql.dll
and restart your apache
I also had this problem on OSX. The solution was uncommenting the extension = pgsql.so in php.ini.default and deleting the .default suffix, since the file php.ini was not there.
If you are using XAMPP, the php.ini file resides in /XAMPP/xampfiles/etc
install the package needed.
if you use yum:
yum search pgsql
then look at the result and find anything that is something like 'php-pgsql' or something like that. copy the name and then:
yum install *paste the name of the package here*
For php 5.4 on Centos 6.10, we include these lines in php.ini
extension=/opt/remi/php54/root/usr/lib64/php/modules/pdo.so
extension=/opt/remi/php54/root/usr/lib64/php/modules/pgsql.so
extension=/opt/remi/php54/root/usr/lib64/php/modules/pdo_pgsql.so
It works.
I encountered this error and it ended up being related to how PHP's extension_dir was loading.
If upon printing out phpinfo() you find that under the PDO header PDO drivers is set to no value, you may want to check that you are successfully loading your extension directory as detailed in this post:
https://stackoverflow.com/a/14786808/2578505
On Gentoo, use USE flag postgres in /etc/portage/make.conf and re emerge "emerge php"
Uncommenting extension=php_pgsql.dll in the php.ini configuration files does work but, you may have to also restart your XAMPP server to finally get it working. I had to do this.
The solution has to do with the fact that your the file holding your php configurations. i.e php.ini has uncommented the extension responsible for acting as the middleman between php and postgres, by placing a ";" in front of the statement "extension=pdo_pgsql"
Quick Fix
Open the php.ini file in your favourite editor. (atom 🙌)
Search for the line "extension=pdo_pgsql", which is under the "Dynamic Extensions" section. (a simple ctrl + f) would get you there quick.
Remove the ";" in front of the line ";extension=pdo_pgsql".
Restart your server.
Go fix more errors like a rock star. 👍
If you got php5.6 using the ppa repository http://ppa.launchpad.net/ondrej/php/ubuntu,
then you should install the package using:
sudo apt install php5.6-pgsql
Finally, if you use apache2, restart it:
sudo service apache2 restart
For those of you who have this problem with PHP 5.6, you can use the following command:
yum install php56w-pgsql
For a list of more package names for PHP 5.6, open the following link and scroll down to packages:
PHP 5.6 on CentOS/RHEL 7.0 and 6.6 via Yum
In windows OS find this in php.ini "php_pgsql.dll" and remove the ";" in the extension then that's it :) Cheeers!

2) Is you Postgresql listenin on 192.168.0.2 interface? (You can check it by netstat -tpln)
3) How you authenticate your access into Postgresql?
Make sure you've uncommented the line that tells php where the Postgres driver is (usually extension=pgsql.so) in the main php.ini file.
I had the same issue. First of all - check is it enabled in php.ini. Uncomment extension=php_pdo_pgsql...
than set up extension directory!!
extension_dir = "ext" ; for your case it could be other dir.
and do not forget to restart server after changing the config.
Try to remove semicolon in front of
extension=pgsql
extension=pgsql.so
included in your php.ini file
You can do that from the XAMPP Control Panel.
Here is what I did to solve the problem.
Edit php.ini and remove ; from extension=pdo_pgsql. Also, add extension=pgsql.so to the php.ini file.
Make sure to restart the Apache server before you try to see the result.
I had the same problem with another solution. I lost my around 4 hours to solve this problem. Please check the following to solve this problem.
Check php.ini file and remove semicolon from this line
extension=pgsql
extension=pdo_pgsql
Restart your apache2 server
sudo service apache2 restart
Check if your PDO driver has updated in localhost phpinfo()
I did All the things right and still I had this problem. And you know why? Because I had several versions of php installed. So I was running php7.4 in my php cli but localhost was running on php7.2. So always check your php versions.
Check your php version on localhost and terminal cli
When you do not have postgresql installed on the same machine that is Apache and PHP; you have to install php-pgsql and don't have to add extensions in php.ini manually in Linux (in Windows yes), because redundancies are generated and this does not work (checked in error.log).
$ sudo apt install php-pgsql
Then you can check the existence of the extension enabled automatically in:
$ sudo nano /etc/php/7.0/apache2/conf.d/10-pdo.ini
Observations: In phpinfo() you will find the directory conf.d/ and the file error.log

Just run php --ini and look for Loaded Configuration File in output for the location of php.ini used by your CLI
then check you have enabled the extensions correctly.
Copy libpq.dll from the PHP directory to Apache24\bin (or wherever your installation could be).
