Hi , In order to enable bcmath I need to recompile php 4.3.4 on suse 8.2. but , I would like to preserve the actual installation just in case anything goes wrong ( as this is my production server) What files should I backup / restore if after compilation php is not working? My actual installation consists of php 4.3.4 With the Zend Optimizer and apache 1.329 Thanks MAuricio -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
