Morning!
Just a quick question.
Say I have a column in my database that could contain NULLS, empty spaces,
or an actual value.
If I do:
$my_query = "SELECT my_column FROM my_database WHERE 1 = 1";
$my_result = ifx_query($my_query, $connect_id);
while($row = ifx_fetch_row($my_result)) {
$my_column = trim($row['my_column']);
if ($my_column != "") {
echo "Test";
}
}
The way PHP assigns the query results to the $my_column variable, wouldn't;
if ($my_column != "") not do anything for the rows that contained NULLS or
empty spaces?
