Re: [PHP-DB] Extracting data from Arrays in ISAM table

Any advise would be appreciated. I have no ideas on how to start.
The best option would be to normalise the data by breaking the names out
to a separate table. However, if that's not feasible my suggestion is
similar to that itoctopus sent, but a bit more memory efficient.
Inside the loop getting the records, do the following...
foreach (explode(',', $single_result['name']) as $name)
$arr_all_names[$name] = 1;
Then after the loop, to get an array of the names...
$arr_all_names = array_keys($arr_all_names);

RE: [PHP-DB] extracting data
Ok,
I am lost now, I am just trying to read the documentation on odbc...here is
what I have so far. This seems to work...or at least not give any errors.
How do I know get to the result set in the select statement to move this
data somewhere else? I just want to get the entire result set so I can load
it into another db.
Thanks,
Eddie

$connect=odbc_connect('mytest','sa', '');

$parms=array(sa,);
$eddie=odbc_execute($stmt, $parms);

You can actually do this from any machine, although you will need an ODBC
driver on the Linux/Mac OS X/Unix side.
Another alternative is to dump the .mdb to mysql format and move it over.
But ODBC is the way to go. Beginning PHP Databases from Wrox cover this a
lot, but you can get started with just a DSN and a basic odbc_connect.
Create it as a System DSN - it will cause less problems.
If you are on a *nix or Mac OS X, then you will want to tell the PHP script
where the files are that contain the DSN (odbc.ini) and the ODBC Driver
Manager (libiodbc.so). There are basic examples and explanations in the
HOWTO at www.iodbc.org. It's *nix geared, but just remove the putenv()'s
at the beninning of the examples and they will work fine.

I posted this to the php general list also so forgive me if you are seeing
this twice. Can I use php to extract data from an access db? The php
script and access db will be local. I will then upload the file to my
server.
Thanks,

RE: [PHP-DB] extracting data
Andrew is correct about iodbc. As soon as they write an allbase connector I
will be all over it.
Here is a function I use to facilitate working with odbc
function odbc_fetch_into_array($rs) {
$result = array();
if (!odbc_fetch_row($rs)) return false;
$numfields = odbc_num_fields($rs);
for($lpLoop=1; $lpLoop=$numfields; $lpLoop++) {
$fieldname = odbc_field_name($rs,$lpLoop);
$fieldval = odbc_result($rs,$lpLoop);
$result[$fieldname] = $fieldval;
}
return $result;
}
It simulates mysql_fetch_array. Usage is similar to mysql.
while( odbc_fetch_into_array($eddie))
{
$myvar1= odbc_result( $eddit, fieldname1
);
$myvar5= odbc_result( $eddit, fieldname5
);
code for this line of table
}
As for how to move the data somewhere else? To another odbc? to mysql?
where? And do you want to manipulate the data before moving it?
Cheers
Jason

[PHP-DB] Extracting data from html files into csv
hi all, I have a huge project coming up today where I need to extract a large number of entries from a directory. What I would like to do is use a site ripper [to download each properties HTML file to a local directory on my pc] and then run some sort of extraction on the file to create an excel, or delimited file. 1. All entries have the same basic format 2. Not all fields are present for each Does anyone know of a program to strip this type of data into a xls or cvs file? thanks much, olinux _ Do You Yahoo!?
