I have this TRIVIAL code and I am pulling my hair out because of it:
<?php
function getAllEvents() {
$sql = "SELECT * FROM events
WHERE eventDate > NOW()
ORDER BY eventDate LIMIT 4";
print $sql;
$result = mysql_query($sql);
var_dump($result)
$list = array();
while ($row = mysql_fetch_assoc($result)) {
$list[] = $row;
}
return $list;
}
with the two diagnostic included as above. I use the sequel statement
in phpmyadmin and it yields four entries and they are correct. However,
the var_dump results in boolean(false) and no results are extracted (of
course).
The column eventDate is configured as DATE.
I have tried replacing the NOW() with the result of date('Y-m-d'), and
played with many other things including turning things into Unix times.
Nothing worked. Removal of the WHERE clause produced results of the
the first four entries by date in the table.
I simply cannot see why the query works properly when used in
phpmyadmin, but fails here. (Yes, they are going to the same database
and same database table.) It seems so simple and is something I have
done a million times.
What can I be missing?

What does mysql_error() say?

You want the first 4 future events, yes?

This turns out to be a "forget it and thanks". I was helping my
daughter with this one and the very first thing I asked her when they
came up with different results was "Are you going against the same
database and table?". She said yes, there was only one.
In working with it more today, she removed some zero date entries from
the table and used a workaround that I gave her. They still appeared,
so I asked her once again "Are you going against the same database and
table?". Then she remembered that she had set up a testing server and,
in fact, they were not the same database. Problem solved.
Thanks Micha.

Yes. See my response to Micha. It was my daughter's not thinking
clearly in answering my question.
