The 'fieldname' that is passed from MySQL to PHP depends upon the terminology of the
SELECT clause (not the
schema of the table). So the column's name is text (BTW not a good choice) but the
query knows the resultant
value as "left(text,64)"
- issue the query from the command line or in an admin pkg, and check the column
headings, if you want to see
what I mean!
Use an AS to give the computed-column a 'good name' and you'll be away:-
$result = @mysql_query("select ID, Writer, left(text,64) as Intro from Reports where
writer like '%kim%';");
...
> $text= $row["Intro"];
