I am connecting to an MS Access database. The connection and exec work
fine. My problem is getting the data.
The following two statement work;
$row = odbc_fetch_array($rs);
$value = $row['Newspaper'];
If I change to
$value = $row[1];
is_null($value) returns true.
What am I doing wrong or is an idiosyncrasy of using MS Access?

This would probably tell more:
print_r($row);

Okay.. Thanks for the response.
Array ( [Newspaper] => Review [Year] => 1887 [Month] => 5 [Day] => 20
[Page] => 4 [Column] => 3 [Father First] => Joe [Father Middle] =>
[Mother First] => [Mother Middle] => [Mother Maiden] => [First] =>
Daughter [Middle] => [Last] => Allen [Date Of Birth] => 05/18/1887
[Date Of Baptism] => [Church] => [Counter] => 1 [NewspaperKey] => 1
[Comments] => )
Hope this helps..
Thanks again.

Okay??? I guess I don't know what I thought I knew!!
Doesn't "odbc_fetch_array" returns an associative array. If so, can't
I address the elements either by name "newspaper" or by index "1".
One minor point, the index I should be using is "0" since the
associative array is 0 based.
Appreciate some suggestions on what I need to address the elements of
my array, $row, via an index value.
Thanks again...

Which is exactly what you should get if you fetch as an associative
array. If you want to access the values by index, you need to fetch
with an indexed array (odbc_fetch_row())/

as I understand it, the array contents have to be defined.
If you define an array with names rather than number, then you can not
assume 0 is going to be the first array item. Or that 0 will be associated
with the first item by default.
$item[0]="aaa"
$item[1]="bbb"
$item['sample']="ccc"
$item['data']="data"
$item[2]="ddd"
If I wanted to recall the third item in the array, I would have to use
['sample'] not [2].
If [2] did not exist, I can not assume [2] would equate to ['sample'].
IOW, what you defined in the array, is what can be recalled.

Richard, odbc_fetch_array() IS defining the array. Just not the way he
expects.

Okay.. obdc_fetch_row() seems to have worked. I was under the opinion
that with an Associative Array the item could be addressed via either
a name or an index. I guess I'm wrong. Apparently an Associative Array
can only be indexed via a string value. Strange...

Go to:
www.php.net
and look at
odbc_fetch_array, odbc_fetch_row, odbc_result

No, there are two different kinds of arrays.

With SQLite, you can use a qualifier to fetch the array as either numeric,
or associative, or both:
http://php.net/manual/en/function.mysql-fetch-array.php
array mysql_fetch_array ( resource $result [, int $result_type =
MYSQL_BOTH ] )
This may be helpful as well:
http://www.phpro.org/tutorials/Introduction-to-PHP-PDO.html
I had problems using associative arrays when, for instance, I wanted to
fetch a series of rows which might be
$db->exec("INSERT INTO tEmail (id,name,email) VALUES (
'$ID', '$Name', '$Email' )");
For some reason I was unable to use the associative indexes in a "for" loop
such as
for( $i = name; $i <= email; $i++)
but this was OK:
$line = 0;
while ($row = $qres->fetcharray(SQLITE3_BOTH)) {
for ($i = 0; $i < 2; $i++) {
$arr[$line][$i] = $row[$i];
}
$name = $arr[$line][1]; // should also be OK to use
$arr[$line][name];
$email = $arr[$line][2];
$line++;
}
I didn't spend much time with it. Since it worked with numeric indexes, I
was OK with that, but associative would have been clearer.

What is the value of 'name' + 1?
Associative array indexes are not numeric, so you can't increment them.
And although SQLLite can return an array with both indexed and
associative arrays, odbc_fetch_array() doesn't.

I was attempting to do what I have done in Borland Delphi, where array
indexes are always numeric, but can be referenced by enumerations that are
simply aliases for numeric values.
Here are ways to emulate that, but it seems too complicated to make it
worthwhile:

I don't know how SQLite does this, but essentially it must create the
equivalent of another associative array which has a 1:1 correspondence of
the text key indexes and a numeric value of the row of the array. I suppose
it would work to assign numeric variables with numeric row indexes, such as:
$nID=0; $nName=1; $nEmail=2;
Then it would probably be legal to use:
For( $i=$nID; $i<=$nEmail; $i++ )
Just some ideas. Thanks.
