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!
