[ PHP-MySQL ] Fatal error: Call to undefined function

[8cc]

RedHat Enterprise Linux 4

Relevant packages installed:
php-4.3.9-3.8
php-mysql-4.3.9-3.8
MySQL-server-standard-5.0.15-0.rhel4

httpd and mysql daemons are both running.

I have a phpinfo() file that shows up perfectly. Okay then, httpd and php are working.
However, when I pull up a simple script to connect to mysql, I get:

PHP Code:

Fatal error: Call to undefined function: mysql_connect() in /var/www/html/connect.php on line 4 


When I first got this error, I read that you had to install the php-mysql package, so I did that, but the error persists. Any help would be appreciated.

EDIT: Forgot to mention that although php was installed with the distro, it indeed has "--with-mysql=shared,/usr" as seen in phpinfo()...
Maybe the "/usr" is the problem since the mysql data directory is /var/lib/mysql?

Found this link: http://www.somacon.com/p109.php

I've done everything there, but still no luck.

Resolution:

Replaced MySQL 5 with MySQL 4.1
