Question on MySQL and PHP


I am trying to write a page in PHP3 running on my Redhat 6.1. I have Apache 1.3.9, MySQL 3.22.27 and PHP 3.0.12 running ok. However, when I want to the following code running my Linux:


$db = mysql_connect('localhost', 'root','');


$result = mysql_query("SELECT * FROM employees",$db);

printf("First Name: %s<br>\n", mysql_result($result,0,"first"));

printf("Last Name: %s<br>\n", mysql_result($result,0,"last"));

printf("Address: %s<br>\n", mysql_result($result,0,"address"));

printf("Position: %s<br>\n", mysql_result($result,0,"position"));


I have the following error:

Fatal error: Call to unsupported or undefined function mysql_connect() in /home/httpd/html/php/showdb.php3 on line 11

It seems that I need to do connections for the PHP an MySQL.  However, most of the document I found on the web just teaching me install and recompile the php3 and mysql from scratch. Do I really need to do it? Can I just change some config file and restart the services? If yes, which file I should change.

I would be appreciated if there is a step by step instruction for!

Have you installed the PHP-mysql module and configured it in the php3.ini? PHP might not use the MySQL module by default, and if that is the case, it would give the error you described.

hi feenix,

Can you tell me how to install the MySQL module? Where I can I find it and how to install it?

Seems like there is no MySQL module for PHP in the RedHat 6.1 CD, strange. But I did find the module from a few places, one is

Just install it (rpm -i package), and then open your /etc/httpd/conf/php3.ini. There should be a section names Dynamic Extensions. There should read:

Then your MySQL module should work okay.
