Does Berkeley DB 4.3.28 work fine PHP 4 ?

Hello! This is leena from pune. I want to use berkeley db with PHP 4. I have installed php extension of berkeley DB on my linux machine. (berkeley db version - 4.3.28 ) I have gone through php extension classes. [http://www.sleepycat.com/docs/ref/ext/php.html] However I m not able to create database with the help of those classes. [ Please take a note that I am not in favor of using php inbuilt dbm style functions as it does not allow to specify access mothods + not fit in my requirements. Anyone know which default method it uses?? ] Here goes my code - [ without creating environment as I am not able to create environment with DB4Env class, it givens segmentation error] /* -------------- */ $db = new Db4(null); $db->open(null,"/tmp/test1.db"-, "test", DB_CREATE, 0666); // Get the current value of "counter" $counter = $db->get("counter"); print "Counter Value is $counter"; $db->put("counter", 5); // put() is not availebale in DB4 still not giving error ??? $db->sync(); $db->close(); /* -------------- */ This program is neither giving error nor creating .db file How to get out of this? Is there any php application uses berkeley DB? Better to using PHP 5 ? Could any one sugesst links or sites where can I get code snippets of php and Berkeley DB? Thanks for the help in advance. Regards, Leena
