I am getting this error Fatal error: Call to undefined function mysql_connect() in /var/www/html/test1.php on line 8
for the following code:
<?php
$host = "localhost";
$user = "user12";
$pass = "34klq*";
ini_set ('display_errors', 1);
$r = mysql_connect($host, $user, $pass);
if (!$r) {
echo "Could not connect to server\n";
trigger_error(mysql_error(), E_USER_ERROR);
} else {
echo "Connection established\n";
}
echo mysql_get_server_info() . "\n";
mysql_close();

I have PHP, MYSQL, php-Mysql installed in my system:
[root#localhost ~]# rpm -qa | grep mysql

output of phpinfo() :

Also I have edited the /etc/php.ini file:
extension=mysql.so
But even then I am getting this error.

You should open your php.ini file located in php folder, and uncomment this line of code:
;extension=php_mysql.dll
So it looks like this:
extension=php_mysql.dll
Your php folder location depends on your lampp/wampp installation, if using xampp its located in: xampp/php/php.ini

if you are working on linux [debian]
apt-get install php5-mysql
because your PHP is not able to talk with mysql

I cheated and looked on my phone
The build of your PHP spectifically says '--without-mysql'
Therefore, mysql functions will not be available.
You should rebuild.

Your PHP is configured with --without-mysql.
The documentation describes how to configure with mysql extension enabled. You may have your reasons, but PDO would be a better choice here is the documentation for configuring with PDO mysql.

Fatal error: Uncaught Error: Call to undefined function db2_connect()

I have some problem. I have been looking it for almost a week. I have done include ibm_db2.dll, change php version but not working. When I run the db2 query, it shows Fatal error: Uncaught Error: Call to undefined function db2_connect() in C:\laragon\www\hpc_dev\db2_conn.php:15 Stack trace: #0 C:\laragon\www\hpc_dev\index.php(3): include() #1 {main} thrown in C:\laragon\www\hpc_dev\db2_conn.php on line 15
Currently I am using php version 7.4.12 64bit (ts) using laragon in Windows 10. I also have tested using Xampp and the same problem occur. Below are my codes to connect to ibm db2:
db2_conn.php:
<?php
ini_set("display_errors", 1);
$database = 'DB2';
$user = 'xxx';
$password = 'xxx';
$hostname = 'xx.xx.xx';
$port = 60000;
$conn_string = "DRIVER={IBM DB2 ODBC DRIVER};DATABASE=$database;" .
"HOSTNAME=$hostname;PORT=$port;PROTOCOL=TCPIP;UID=$user;PWD=$password;";
$conn = db2_connect($conn_string, '', '');
if ($conn) {
echo "Connection succeeded.";
db2_close($conn);
}
else {
echo "Connection failed.";
}
?>
My code to show data from db2:
<?php
include("db2_conn.php");
$sql = "SELECT * FROM EMPLOYER WHERE EMPR_LOGIN_NAME = 'xxxxx'";
if ($conn)
{
$stmt = db2_exec($conn, $sql);
$row = db2_fetch_assoc($stmt);
echo $row['SECTOR_DESC'];
db2_close($conn);
}
?>
I don't know either the problem comes from db2 extension or others. Please help me.
For information, I have download the ibm db2 extension here: https://github.com/ibmdb/php_ibm_db2
Thanks
Your question omits details of the command-lines and actions you performed.
Most likely you missed a step in the configuration.
Remember to open the laragon terminal and verify that the Db2 driver is loaded:
php -m | grep ibm
should return ibm_db2 if you have correctly configured the correct version of the extension.
If you do not see that the ibm_db2 extension is loaded then any db2_connect will fail until you resolve the missing module.
For information the current laragon_full (November 2020) delivers PHP 7.2 TS, and that works correctly with the php_ibm_db2.dll TS for v7.2.x "out of the box" (which you must first download and configure).
Additionally, if I upgrade the PHP version for laragon to PHP 7.4.12 TS, and subsequently download and configure the matching php_ibm_db2.dll TS for php v7.4.x, then it all "just works" without any issues on Win 10 x64 2020 to connect to Db2-LUW and run queries etc.
It helps to verify that your Db2 client is correctly configured. You can do that independently of PHP. If you are using the clidriver Db2-client (the smallest footprint driver) you can configure the db2dsdriver.cfg XML file and then run db2cli validate -connect -dsn -user ... -passwd ... to verify that the connection works. If you are using either the Db2-runtime-client or the Db2 full client, or a local Db2-server, you can run (in the laragon terminal):
(after configuring your Db2 node directory and Db2 db directory via appropriate configuration commands )::
set DB2CLP=**$$**
db2 connect to $yourdsn user ... using ...

Uncaught Error: Call to undefined function odbc_connect() [duplicate]

I'm testing out php 7 and have come across this error:
Fatal error: Uncaught Error: Call to undefined function odbc_connect()
From the doc page: http://php.net/manual/en/function.odbc-connect.php php 7 is not listed as supported.
Does anyone have a way around this or know when it will be supported?
Thanks#
There is written in doc: ODBC support doesn't need any extension dll. It is true in PHP 5.x, I had to remove "extension=php_odbc.dll" from ini file.
But in PHP 7 I had to put it back.
I found the file "ext/php_odbc.dll" in the new PHP 7 directory again. It works for me :).
The DOC page does list PHP 7, so just install php-odbc and you should be good to go. Currently using it myself on RedHat EL7 with Remi php7.
I ran into the same problem. However according to the link you provided PHP7 is in fact supported. So I'm not sure why you have so many comments telling you to go re-write your code.
This is what ultimately fixed the issue for me:
sudo apt-get install php-odbc
Followed by restarting Apache.
PHP 7.2.7, add extension=php_odbc.dll in php.ini file while either using database as MS Access or Sql Server
C:\xxxxxx\php\php.ini
*no semicolon before to extension=php_odbc.dll
Just enble "php_odbc.dll" extension by removing the semicolon and restart Apache.
If there is no such line in php.ini, simply create it on yourself (you will find many similar lines in php.ini) by adding: extension=php_odbc.dll and then restart Apache.
If Apache does not start or cannot load php_odbc.dll, look into to the ext-Folder of PHP, if there is such a DLL called php_odbc.dll. If there is no such DLL, Xampp/PHP7 does not support ODBC natively. In that case you should install an older Xampp Version with PHP 5.x
From php.ini file:
> ; Notes for Windows environments :
> ;
> ; - ODBC support is built in, so no dll is needed for it.
> ; - Many DLL files are located in the extensions/ (PHP 4) or ext/ (PHP 5+)
But, in PHP 7, ODBC is not by default. Explicit
extension=odbc
worked for me (new syntax recommended)
Edit:
If your architecture is x64
you must use C:\Windows\SysWOW64\odbcad32.exe
instead of C:\Windows\system32\odbcad32.exe
Here is the error message:
Redhat PHP Fatal error: Uncaught Error: Call to undefined function
odbc_connect()
On Redhat Linux 7 you run:
yum install php-odbc
You will get these packages marked in red:
Code sample to test your connection via php command line run: php [filename].php

PDO will not run since upgrading PHP to 5.4.22

I just recently upgraded my server's PHP version to 5.4.22, and now every script that uses PDO does not work.
An example of my PHP script which won't work:
<?php
$dsn = 'mysql:dbname=testDB;host=127.0.0.1';
$user = '[hidden]';
$password = '[hidden]';
try {
$pdo = new PDO($dsn, $user, $password);
} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
exit;
}
?>
When i run the script i get: Fatal error: Class 'PDO' not found, i get this same error for every script that creates a connection.
I ran a check on puTTY to check PDO was even there and it found this:
root#cpanel [~]# php -m | grep -i pdo
PDO
pdo_mysql
pdo_sqlite
My php.ini has
extension=pdo.so
extension=pdo_sqlite.so
; sqlite was removed by EasyApache v3.22.24 on Sat Dec 14 23:24:10 2013 (PHP v5.4.x incompatibility)
; extension=sqlite.so
extension=pdo_mysql.so
phpinfo(); in PHP file claims im on PHP Version 5.3.10
How ever in my terminal # php -v says PHP 5.4.22
So this had really confused me why i'm getting two versions.
Your question shows that you are checking the PHP version via the command line. But PHP via a web browser is going to use a module loaded into Apache which is a completely different thing. So check the output of phpinfo(); in a PHP script loaded via the web browser. Is PDO installed or shows as installed via that?
Wherever your Apache config files are look for the directory mods-available and the file php5.load. Under Ubuntu 12.04 it would be in this path:
/etc/apache2/mods-available/php5.load
And the contents should be:
LoadModule php5_module /usr/lib/apache2/modules/libphp5.so
Does the path in that file match where the newly compiled libphp5.so is installed?
Also, that LoadModule php5_module line could be a part of your main Apache configuration. Look around to find where that is set. And then just set the path of the new module to me wherever it’s actually installed.

Fatal error: Call to undefined function mysql_connect() [duplicate]

Fatal error: Uncaught Error: Call to undefined function mysql_connect()

Closed 3 months ago.
I have set up PHP, MySQL, and Apache. localhost() for PHP and it is working well. But after I downloaded MySQL, it reports:
Fatal error: Call to undefined function mysql_connect()
How can I fix this?
You upgraded to PHP 7, and now mysql_connect is deprecated. Check yours with:
php -version
Change it to mysqli_connect as in:
$host = "127.0.0.1";
$username = "root";
$pass = "foobar";
$con = mysqli_connect($host, $username, $pass, "your_database");
If you're upgrading legacy PHP, now you're faced with the task of upgrading all your mysql_* functions with mysqli_* functions.
If you get this error after upgrading to PHP 7.0, then you are using deprecated libraries.
mysql_connect — Open a connection to a MySQL Server Warning This
extension was deprecated in PHP 5.5.0, and it was removed in PHP
7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used.
More here: http://php.net/manual/en/function.mysql-connect.php
Open your terminal and run bellow command.
sudo apt-get install mysql-server
If you are running PHP you will also need to install the php module for mysql 5:
sudo apt-get install php5-mysql
Verify that your installation of PHP has been compiled with mysql support. Create a test web page containing <?php phpinfo(); exit(); ?> and load it in your browser. Search the page for MySQL. If you don't see it, you need to recompile PHP with MySQL support, or reinstall a PHP package that has it built-in
PHP.INI
Check if you forgot to enable the options below(loads the modules for mysql among others):
; Directory in which the loadable extensions (modules) reside.
; http://php.net/extension-dir
; extension_dir = "./"
; On windows:
extension_dir = "ext"
Use.
<?php $con = mysqli_connect('localhost', 'username', 'password', 'database'); ?>
In PHP 7.
You probably have PHP 7 in XAMPP. You now have two option: MySQLi and PDO.
For CPanel users, if you see this error and you already have PHP 5.x selected for the site, there might be a CPanel update that disabled mysql and mysqli PHP extensions.
To check and enable the extensions:
Go to Select PHP Version in CPanel
Make sure you have PHP 5.x selected
Make sure mysql and mysqli PHP extensions are checked
This error is coming only for your PHP version v7.0.
you can avoid these using PHP v5.0
else
use it
mysqli_connect("localhost","root","")
i made only mysqli from mysql
A solution could be to use adapter functions like these to start using mysqli instead of mysql over your entire application:
if (!function_exists('mysql_connect')) {
function mysql_connect($host = '', $user = '', $password = '', $database = '', $port = 0, $socket = '') {
return mysqli_connect($host, $user, $password, $database, $port, $socket);
}
}
if (!function_exists('mysql_select_db')) {
function mysql_select_db($link, $dbname) {
mysqli_select_db($link, $dbname);
}
}
I had this same problem on RHEL6. It turns out that the mysql.ini file in /etc/php.d only had a module name but needed a full path name. On my RHEL6 system the entry that works is:
; Enable mysql extension module
extension=/usr/lib64/php/modules/mysql.so
After modifying the file, I restarted apache and everything worked.
My solution is here (I needed just to remove the last slash (NB: backward slashes) from PHPIniDir 'c:\PHP\'): Fatal error: Call to undefined function mysql_connect() cannot solve
Am using windows 8 n this issue got resolved by changing the environment variables
follow these steps:
Open my computer properties->advanced system settings->Environment variables.
Under 'system variables', select 'path' and click on 'edit'
In 'variable value', add 'C:\php;' OR the path where php installed.
click OK and apply the settings and restart the system.
It should work.
Here is a quick fix:
All the pros will probably hate me for this answer. But I got the same error on a server: Fatal error: Uncaught Error: Call to undefined function mysql_connect() that was using PHP 7. Did not have time to rewrite all the mysql code so a quick, temporary fix if anyone needs it is in CPANEL to look for PHP Configuration and change the version for that account to something like PHP 5.4 instead of PHP 7. Then the code worked fine without the above error.
If you are using Windows10, PHP 7.2 and try to connect to mysql.
If this error occurred
Uncaught Error: Call to undefined function mysqli() in
The do the following steps to get it correct.
Go to the PHP installation folder,
CHeck for php.ini file, (Only dev, prod file is there, then one of the file as php.ini file)
Look for "extension=mysqli" and remove the ";" before it.
Look for "extension_dir" and mentioned the path of "ext" directory.
Restart the application.
Hope this helps to someone.
Check if mysqli module is installed for your PHP version
$ ls /etc/php/7.0/mods-available/mysql*
/etc/php/7.0/mods-available/mysqli.ini /etc/php/7.0/mods-available/mysqlnd.ini
Enable the module
$ sudo phpenmod mysqli
This Code Can Help You
<?php
$servername = "localhost";
$username = "root";
$password = "";
$con = new mysqli($servername, $username, $password);
?>
But Change The "servername","username" and "password"
The problem shows up when you're using mysql_connect in your code lines so just add it as in mysqli_connect and it will solve the problem.
You also have to then use mysqli throughout your code lines or the problem would surface again.
The example mysql_select_db will then be mysqli_select_db for selecting Database.
