I have just upgraded to PHP 5.2 from PHP 4. I am using Apache 2 with MYSQL. Before the upgrade, everything was working well. (Was able to connect to my MYSQL database from PHP interface. However, now with the same PHP codes, I am not able to connect to the MYSQL database instead I am getting errors such as: *Fatal error*: Call to undefined function mysql_connect() in *C:\Program Files\Apache Group\Apache2\htdocs\viewusers.php* on line *7 Line 7 is: $dbc = mysql_connect ('localhost') OR die ('Could not connect to mysql: ' .mysql_error() ); *However, this was working fine before the upgrade. WHAT DO I NEED TO DO. In a second attempt to fix the problem, I dited the system path to the directory where php is installed. Now the error message is gone but still cannot to the database. Whilst I tried to retrieve data from the database using the PHP scripts, nothing comes from the database. Also I tried to post but the data is not put in the data.base Note when I upgraded to PHP 5, I still left the PHP 4 files in the computer. PLEASE HELP ME -- Thank you very much. Abdou Karim Jallow
