Call to undefined function mysql_connect windows

I just installed PHP and Apache on my home PC. When I try to call function mysql_connect I get:

fatal error: call to undefined function mysql_connect.

I have loaded php.ini where I have uncommented lines extension=php_mysql.dll and extension=php_mysqli.dll and changed extension directory to extension_dir = "C:\php\ext" - which is the directory where files php_mysql.dll and php_mysqli.dll are. How can I fix this problem?

After looking at your phpinfo() output, it appears the mysql extensions are not being loaded. I suspect you might be editing the wrong php.ini file (there might be multiple copies). Make sure you are editing the php file at C:\php\php.ini (also check to make sure there is no second copy in C:\Windows).

Also, you should check your Apache logs for errors (should be in the \logs\ directory in your Apache install.

If you haven't read the below, I would take a look at the comments section, because it seems like a lot of people experience quirks with setting this up. A few commenters offer solutions they used to get it working.

Another common solution seems to be to copy libmysql.dll and php_mysql.dll from c:\PHP to C:\Windows\System32.

Background about my (similar) problem:

I was asked to fix a PHP project, which made use of short tags. My WAMP server's PHP.ini had short_open_tag = off. In order to run the project for the first time, I modified this setting to short_open_tag = off.

PROBLEM Surfaced: Immediately after this change, all my mysql_connect() calls failed. It threw an error

fatal error: call to undefined function mysql_connect.

Solution: Simply set short_open_tag = off.

My PC is running Windows 7 (Apache 2.2 & PHP 5.2.17 & MySQL 5.0.51a), the syntax in the file "httpd.conf" (C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\httpd.conf) was sensitive to slashes. You can check if "php.ini" is read from the right directory. Just type in your browser "localhost/index.php". The code of index.php is the following:

There is the row (not far from the top) called "Loaded Configuration File". So, if there is nothing added, then the problem could be that your "php.ini" is not read, even you uncommented (extension=php_mysql.dll and extension=php_mysqli.dll). So, in order to make it work I did the following step. I needed to change from

PHPIniDir 'c:\PHP\'

to

PHPIniDir 'c:\PHP'

Pay the attention that the last slash disturbed everything!

Now the row "Loaded Configuration File" gets "C:\PHP\php.ini" after refreshing "localhost/index.php" (before I restarted Apache2.2) as well as mysql block is there. MySQL and PHP are working together!

You have probably forgotten to restart apache/wamp/xamp/whatever webserver you use, you need to do that in order to make it work

Check your php.ini, I'm using Apache2.2 + php 5.3. and I had the same problem and after modify the php.ini in order to set the libraries directory of PHP, it worked correctly. The problem is the default extension_dir configuration value.

The default (and WRONG) value for my work enviroment is

; extension_dir="ext"

without any full path and commented with a semicolon.

There are two solution that worked fine for me.

1.- Including this line at php.ini file

extension_dir="X:/[PathToYourPHPDirectory]/ext

Where X: is your drive letter instalation (normally C: or D: )

2.- You can try to simply uncomment, deleting semicolon. Include the next line at php.ini file

extension_dir="ext"

Both ways worked fine for me but choose yours. Don't forget restart Apache before try again.

I hope this help you.

Hi I got this error because I left out the ampersand (&) in

; php.ini
error_reporting = E_ALL & ~E_DEPRECATED

Be sure you edited php.ini in /php folder, I lost all day to detect error and finally I found I edited php.ini in wrong location.

After change our php.ini, make sure to restart Apache web server.

Just for future reference, copying all these extension files to Windows/System or Windows/System32 is unnecessary.

All that is required is a copy of the php.ini file you edit in the PHP dir to copied to the root Windows dir.

phpinfo will clearly explain the below: Configuration File (php.ini) Path C:\Windows

Logical sense will explain that php wants to load a config located in the Windows dir. :-)

One time I had a problem while using Off instead of off. And also check the pads one more time... The path has to be exact. Also add the following line to your environmental variable.

C:\your-apache-path\bin; C:\your-php-path\bin;C:\your-mysql-path\bin

If you are in Windows, right click My Computer, select properties, and navigate to the Advanced tab... (is Windows 7). Click on Advanced system settings first then select the Advanced tab and then Environmental variables. Select PATH and click on Edit. Make a copy of the string in a .txt file for back up (it might be empty)--- set your environmental variables... Log out and log back in.

Since mysql_connect 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. by default xampp does not load it automatically

in your php.ini file you should uncomment

;; extension=php_mysql.dll

to

extension=php_mysql.dll

Then restart your apache you should be fine

This same problem drove me nuts (Windows 10, Apache 2.4, MySql 5.7). For some reason (likely PATH related), the .dlls would not load after uncommenting the correct exension dlls and extension_dir = "ext" in php.ini. After trying numerous things, I simply changed "ext" to use the full directory path. For example. extension_dir = "c:/phpinstall/ext" and it worked.

I think that you should use mysqli_connect instead of mysql_connect
