Plz help quick - mysql/php/web server undefined function all of a sudden

I have a web server that uses mysql-4.1.0/apache-2.4.6/php-4.3.4 on freebsd-5.1. It has been working fine for the past few years, now all of a sudden today I get an undefined function error. This is from httpd-error.log - PHP Fatal error: Call to undefined function: mysql_connect() in /...<stuff> This is the connection function I am using - <? $conn=mysql_connect("localhost","user","") or die ("Could not connect to the server"); mysql_select_db("simradusa", $conn) or die ("Could not get the database"); ?> If I comment out the above function the pages will load but of course none of the database stuff will load. If I leave the lines with the connect function uncommented the page fails to load altogether. As I mentioned - this just suddenly came about either today or over the weekend, I know it worked friday when I left the office. This particular machine has been up for 151 days 22 hours without a hiccup. thanks for the help, -- Chip Wiegand Computer Services Simrad, Inc www.simradusa.com chip.wiegand@simrad.com "There is no reason anyone would want a computer in their home." --Ken Olson, president, chairman and founder of Digital Equipment Corporation, 1977 (Then why do I have 8?
