Re: [PHP] reading records alphebetically From: Jack Sasportas (jack <email protected>)

Since you only have a few records, creating a second index with the first
letter doesn't apply to you, but is a good idea in a huge db scheme.

The simplest & fastest way is to take the suggestions a few people made which
is
SELECT * FROM
table WHERE name LIKE '$letter%'

I would not suggest this
$result = mysql_query("SELECT * FROM table order by name");
while ($row = mysql_fetch_array($result)) {
  extract($row);
   $first_letter = strtolower($name[0]);
 }

NOT that it won't work, but you should consider CPU in your design, and you
don't want to make the computer go through all the records sequentially to
display the valid records. This would take a lot longer to deliver the results
in a large file, and would consume more resources...
