Hello everyone,
I am a new PHP user, from Belgium. I am trying to manage a MySQL database with PHP,
and I kindly request your help to solve a little (probably very stupid) problem I have
been dealing with for a while already ...
I have a MySQL database (called "sessions") with a auto-increment INT field called
"sessionID". I try to check if there is already a record in this database with a given
sessionID, which is called $sessionID in PHP. I use this query, which must be wrong
(but I cannot find out why !!!) :
SELECT * FROM sessions WHERE sessionID = $sessionID
Even though there is already a record with the right sessionID, my program does not
find it (I always get 0 when using mysql_num_rows() after the query). Though, if I
replace "$sessionID" by, for example 4, then that works and it says there is already a
record with that ID.
I guess the problem comes from comparing two different kinds of variables, but I can't
fix it ... Could anyone please help ? By advance, thank you !!!
Best regards from Belgium,
Jean-marc
