i will try to help you
but think i'm old in Fox but new in php
and sadly never used php+fox
so, reading your code
i see you are scanning the whole dbf file from php
Fox cant help you in this way
if there is not another option for scan a dbf
the row by row method is very slow

Your post definitely gives me hope. It's possible I'm doing something
wrong!
I definitely have the foxpro database indexed. I use this FoxPro command
...
INDEX ON PHONE TAG PHONE
I do have a .CDX file present for the Database and if I MODIFY STRUCTURE
and I can see the INDEX present on PHONE.
Did you check my Code? Is there any other way to pull records off a
FoxPro Database? Can you use SQL Commands via PHP on FoxPro databases
(SELECT * FROM .... ) ?
Thanks

even though the dbf has 10K records
Fox can't spend "minutes" to found a match
by the way, its very strange
to have 35 columns in a table/dbf or whatever....
pay attention to the comment of Ashley
in Fox, you should:
SELECT directory
INDEX on phone_number to idx_directory_phone
- or -
INDEX on phone_number tag phone of cdx_directory
i worked with Fox
with dbfs of 2 millions of records
and the speed is amazing -- using indexes of course!

Ave,
I'm connecting to a foxpro database (dbase) and simply running a
search to retrieve a record. It's a very simple code.
The problem is, as the database is growing, the search is becoming
ridiculously slow ... and I mean it's taking "minutes". When the
dbase had 10,000 records ... search was fast & efficient ... as if
you were connecting to a mySQL Database. Now that the database has
over 75,000 records and still growing ... it's taking minutes to search.
The database has about 35 fields; Search is based on a phone number.
This is the code ...
<?php
#Open DBF
$db = dbase_open("dbase.dbf", 0);
#PULL UP RECORD
if ($db) {
$record_numbers = dbase_numrecords($db);
for ($i = 1; $i <= $record_numbers; $i++) {
$row = dbase_get_record_with_names($db, $i);
if ($row['PHONE'] == $_POST['PHONE']) {
#Retrieve row & display fields
echo $row['STUFF']; } }
}
?>
It works ... but it's getting way too slow.
One thing with FoxPro DBF's is that they use an Index file for
searches within FoxPro. These are .CDX files which contain the Index.
You can create an Index on, for example, PHONE field. However I don't
think there's any way in PHP to reference this Index file for faster
searches.
Is there any possibility to improve search response time?
Thanks!
