My code is like this:
if( ($this->master=socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0 )
{
die("socket_create() failed, reason: ".socket_strerror($this->master));
}
when I run my php file which create connection with web socket, I got error
Fatal error: Call to undefined function socket_create() in the line
if( ($this->master=socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0 )
Therefore i am not able to connect web socket and also not able to get response message from socket because Socket Status: 3 (Closed) is displaying in my browser when run client page .
Have you got an idea what is missing?
Thank you in advance.
You'll need to install (or enable) the Socket PHP extension: http://www.php.net/manual/en/sockets.installation.php
For a typical XAMPP install on windows you probably have the php_sockets.dll in your C:\xampp\php\ext directory. All you got to do is go to php.ini in the C:\xampp\php directory and change the ;extension=php_sockets.dll to extension=php_sockets.dll.
If you are using xampp 7.3.9. socket already installed. You can check xampp\php\ext and you will get the php_socket.dll. if you get it go to your xampp control panel open php.ini file and remove (;) from extension=sockets.
Open the php.ini file in your server environment and remove ; from ;extension=sockets. if it's doesn't work, you have to download the socket extension for PHP and put it into ext directory in the php installation path. Restart your http server and everything should work.
Follow these steps if you're on openSuse or SUSE.
Install php7 if it's not already installed.
zypper in php7
If you have php7 installed, update it with:
zypper update php7
Install php7-sockets
zypper in php7-sockets
Sometimes the version of your xampp (wamp or ...) is different with CLI. I suggest first using php --ini to find that use a correct version.
Moreover to solve this problem, you can open your xampp and use shell.
I got this error when my .env file was not set up properly. Make sure you have a .env file with valid database login credentials.
I just changed my server and experience these errors below:
Fatal error: Call to undefined function mysqli_init() in /home/blacktwitter/public_html/system/database/drivers/mysqli/mysqli_driver.php on line 126

Website is in Codeigniter. It works on one server very well and on the local machine too. But when I upload that website at the new server I have that errors. Of course I changed important parameters like database connection, base_url() etc.
I was suspicious about database, but I have created a new database and user etc. and changed connection info.
Why does this happen? It will be helpful to know if it is a bug at the server or at the website. Also when I create some index.html with some test code everything is fine.
It is not a bug in your application, it is just a missing driver, so, you have couple of options...
Go to your php init and uncomment the following:
extension=php_mysqli.dll
If not, try installing it at your server, it varies depending on your distribution.
Try installing php5-mysqlnd
If you cannot do it by hosting restrictions then just move to mysql driver (wont need to change other configurations or queries in CodeIgniter or anything else...)
like this (at your config file)
$db['default']['dbdriver'] = 'mysql'; (you might have mysqli now)
I just had this issue on a ubuntu16.04, php7.1 install with Codeigniter 3.
Solution was simple (if hard to find!)
sudo apt-get install php7.0-mysql
I realised that the mysql*.ini files where missing from the etc/php/7.1/mods-available directory. Not sure how it happened, but that worked for me.
If you use 7.2, simply type sudo apt-get install php7.2-mysql
Use this:
sudo apt-get install php7.*-mysqli
or
sudo phpenmod mysqli
sudo service apache2 restart
This is actually not a CodeIgniter issue but PHP installation issue.
I have installed PHP5.6 in my Linux server and is having a hard time following the googled solutions of using the ff command in order to install the missing mysqli_extension in PHP.
What I tried is but is returning the warning message: Unable to locate package php5-mysqli
sudo apt-get install php5-mysqli
However, my php version is 5.6 so I tried
sudo apt-get install php5.6-mysqli
Then it works.
The problem is php's mysql extension might not have installed, if you are using php 7, just issue the below command and install the extension,
sudo apt-get install php-mysql
Open the folder where you have installed PHP, Edit php.ini file
uncomment this line:
extension=php_mysqli.dll
I know the difference is not that big but for the ones who are running CentOS:
sudo yum install php-mysqli
sudo systemctl status httpd
We are installing the mysqli extension using yum and then restarting our httpd server for the changes to take effect, and in case you are not using httpd just replace httpd for the name of your service.
For me this was a missing line in php.ini that solved it, as I copied another php.ini file to my XAMPP installation.
Worth checking if the line: "extension=php_mysqli.dll" exist (if running Windows, but this isn't applicable for OP, as it's a Linux system), or if the "extension_dir" exists and is correct.
1、apt-get install (yum, compile install whatever) php5-mysqlnd extension.
2、if not work, make sure mysqli is loaded
root#x19-ws07-1:/etc/php5/apache2# cat /proc/31682/maps | grep mysql
if is loaded, you can see:
7f2cd3266000-7f2cd3285000 r-xp 00000000 fd:00 864561 /usr/lib/php5/20131226/mysqli.so
7f2cd69ef000-7f2cd6a2e000 r-xp 00000000 fd:00 864559 /usr/lib/php5/20131226/mysqlnd.so
3、if not loaded use php --ini to find config file
xxxx#xxxx:~$ php --ini
Configuration File (php.ini) Path: /etc/php5/apache2
Loaded Configuration File: /etc/php5/apache2/php.ini
Scan for additional .ini files in: /etc/php5/apache2/conf.d
Additional .ini files parsed: /etc/php5/apache2/conf.d/05-opcache.ini,
/etc/php5/apache2/conf.d/20-mysqli.ini
4、if not config extension, config like this and remember restart your web server
xxxx#xxxxx:~$ cat /etc/php5/apache2/conf.d/20-mysqli.ini
; configuration for php MySQL module
; priority=20
extension=mysqli.so
In Linux, you can install MySQL driver extension.
sudo apt-get install php-mysql
In Windows with XAMPP, the driver has already saved in ext directory, but you need to enable it in php.ini. You need to uncomment this line:
extension=php_mysqli.dll
You also need to check the extension directory location in php.ini. I use absolute path (not relative path) declaration to make it works.
extension_dir="your\absolute\path\to\xampp\php\ext"
For example,
extension_dir="C:\xampp\php\ext"
I tried, comment out below line in /etc/php/cli/php.ini file.
extension=php_mysqli.dll
I am using Ubuntu 16.04 on AWS-EC2 instances and PHP 7.0. This solved my problem.
In my case using Windows I had all the necessary extensions uncommented, but it wasn't loading them. Then, I checked the extension directory variable in php.ini and it was as "ext", but then I remembered I'd had a similar problem previously. So what I did was basically put the explicit directory. Something like this:
extension_dir = "C:\php\ext"
Of course the specific ext directory depends entirely on your own setup and locations.
After updating the php.ini file you just have to restart Apache to apply the changes.
If you installed your Apache manually (not using pre-packaged solutions like XAMPP or WAMPP) you just have to use these commands in either a Command Prompt or a Powershell with administrator rights.
net stop Apache2.4
net start Apache2.4
If your webserver is running with a lower version of MySQL, then you will get this error as MySQLi is not supported in MySQL < 4.1.3
It is highly recommended to go with MySQLi instead of going back to MySQL extension.
More info on php.net
I suggest you do the following:
change:
'dbdriver' => 'mysqli',
'dbprefix' => '',
to:
'dbdriver' => 'mysql',
'dbprefix' => '',
in database.php file.
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!
Hi I have tryed to install zend framerwork on Ubuntu 14.04.
in installing steps I have changed
/etc/php5/apache2/php.ini

After than my other php project stoped working.

You have to restart your php process, or in your case, likely apache -
$ sudo service apache2 restart
In other cases, it could be :
$ sudo service php5-fpm restart
Or I've even seen
$sudo service httpd restart
In both cases, it seams that you have a typo, you try to include a file named:
view/display/home .php
where it should probably read:
view/display/home.php
without the extra space... between home and .php
Check your apache error logs to see if you have another error in your php.ini file. I had an error somewhere else, and apache was pretty much ignoring my ini file after encountering the error.
I am trying to use the new facebook api and it requires libcurl PHP. I used
sudo apt-get install php5-curl
sudo apachectl -k restart
And it didn't work. I get the same error and the phpinfo() page says nothing about libcurl.
The source of this problem is probably that I built some of the tools from source (apache2, php), but then I got bored so installed a lot of the extensions with the package manager. But I'm not exactly how to go about diagnosing the point of failure.
The apt-get install for curl definitely worked, and can be found in
/usr/lib/php5/20060613/curl.so
I think a lot of my confusion stems from not knowing which files go where, and what purpose they have. Any help would be appreciated, and please tell me if I need to provide more information.
edit:
The specific error I get is:
Exception: Facebook needs the CURL PHP extension.
from line
if (!function_exists('curl_init')) {
throw new Exception('Facebook needs the CURL PHP extension.');
}
Ubuntu: 9.10
PHP: 5.2.13
Loaded Configuration File: /etc/php5/apache2/php.ini
In general it's a bad idea to mix and match software from your distribution's package manager with stuff you've built yourself. The package manager will not know anything about the stuff you've built yourself and so can get confused.
Not only that but who's to say the stuff from the package manager is even binary compatible with the stuff you've built yourself? If you build it all yourself then at least you know it will all be compatible.
Sounds to me like you should uninstall the extensions and build them yourself. If you can't or don't want to do that then go back and install apache and friends through your package manager but I would recommend having patience and going for the former option.
Answer of Questions
What version of Ubuntu?
What version of PHP?
How is Apache and PHP set up?
What ini files does phpinfo() say is parsed? (should be near the top)
Perhaps apt failed to properly modify your php.ini file to load the curl extension?
Check out your php.ini and see if you have line like:
extension=curl.so
or maybe:
extension=/usr/lib/php5/20060613/curl.so
To check if php-curl is installed please follow these steps:
Create a file in your web server (in Ubuntu it would be in /var/www folder), name it info.php
Open that file and type this command:
<?php phpinfo(); ?>
Save that file
Open your favorite browser and open that file (ex: http://localhost/info.php)
Now you will see the Information about your PHP installation
Search for Curl, and if you cannot find it, it mean your php doesn’t have curl installed.
To install php-curl please follow these steps:
Open your terminal and type this command:
sudo apt-get install curl libcurl3 libcurl3-dev php5-curl php5-mcrypt
After it finish open php.ini file (mine is at /etc/php5/apache2/php.ini ) and add this command: extension=curl.so
Save the file and restart apache with this command:
/etc/init.d/apache2 restart
Check the PHP information page again, you will find PHP-CURL installed
That’s it
