Hi,
sorry if maybe this is a bit dumb question, but I'm a begginer with php...
I got a mysql database, where two of the fields of a table record times as
CHAR(8) in the format hh:mm:ss
I want to take this two times and get the difference between them in
seconds, for example 12:01:30 - 12:00:00

Talking under correction, but you'll be better of using a TIME column in
MySQL. You can also do all the calculations with MySQL's build in time
functions already, which will save you allot of time, seeing that all the
calculations can be done via a single

First of all, if you're storing time then you're better off using the
DATETIME column type. Even though it may take a bit more space than
CHAR(8), unless you absolutely need the ultimate in table optimization,
use DATETIME.

note that I put:
$startTime = $linea[startTime];
I misppeled it while copying, this shuold be
$startTime = $line[startTime];

Thank you very much Erik, I'll try it :)
anyway, it would be nice to know what's wrong with the code I posted, why
does it work with CHAR and not with TIME types?

That error means your query failed and the result set is not valid. You
can't use LIKE on a TIME column.
Can you explain exactly what you want? How are you storing the times,
what are the times, what kind of data do you want to pull out of the
table?

This is one of those situations where having your database using the
most appropriate field types would help. When you've got it as CHAR
there's little you can do in the way of
