FoxPro created .CDX files for Indexes. The problem is - does PHP use those indexes? And the secondary question is whether you have enough memory to 'permanently' cache those indexes? They don't improve performance very much unless they are kept in local memory all the time. The only way to fix this is to move to a real DBMS engine. Bob McConnell Well that might be a problem. The indexes, along with the files, are stored on the network and they are accessed over the network, not locally. Although to be fair; I have tried using a copy of the DBF it's Index File (CDX) locally and it didn't make any difference to the search. Either way, it all points in the same direction ... using a modern DBMS. It's just a problem on our end because all our customer data is in FoxPro databases and all the other applications are written for those FoxPro databases. --- Rahul Sitaram Johari Founder, Internet Architects Group, Inc.

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!

Your post definitely gives me hope. It's possible I'm doing something

I definitely have the foxpro database indexed. I use this FoxPro

INDEX ON PHONE TAG PHONE
I do have a .CDX file present for the Database and if I MODIFY

Did you check my Code? Is there any other way to pull records off a

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!

[PHP] Re: dbase_get_record_with_names; Very slow search!!!
uhh, i don't know
(time ago Fox was multi-platform unix/mac/dos)
did you found that on the web?

I do believe that what I'm doing is scanning the foxpro dbase row by
row to get the match ... which is why it's returning the results very
slow.
But I don't know if there's any other way to do this. Basically the
FoxPro DBF has 75,000 records and I have to search for the one row
which has the Phone number I'm looking for, and display results. If
there's any other way to do this ... I'll be more then happy to try.

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

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!

Re: [PHP] Re: dbase_get_record_with_names; Very slow search!!!
Back in 1996 FoxPro was multi-platform. The last FoxPro version
released for Mac was Visual FoxPro 3.0b (1996). After that Microsoft
bought FoxPro and Mac Support/Development was cut off. As of now,
there are NO known ODBC Drivers for FoxPro for the Mac Platform.
So that aside ... back to Original Topic:
Still no solution for a faster search through the dbf via PHP.
