Description:
------------
After executing a "SELECT" SQL query and then doing an odbc_fetch_array(), field names longer than 31 characters gets truncated.

Reproduce code:
---------------
<?php

$link = odbc_connect('MYSQL', '', '');  //  Connect to MySQL
$res = odbc_exec($link, 'select * from test');
var_dump(odbc_fetch_array($res));


$link = odbc_connect('Access', '', '');  //  Connect to Microsoft Access
$res = odbc_exec($link, 'select * from test');
var_dump(odbc_fetch_array($res));

?>

Expected result:
----------------
Assuming that a field name within the table `test` is '1234567890123456789012345678901234567890', expected result maybe like:

array(1) {
  ["1234567890123456789012345678901234567890"]=>
  string(1) "1"
}

array(1) {
  ["1234567890123456789012345678901234567890"]=>
  string(1) "1"
}

Actual result:
--------------
array(1) {
  ["1234567890123456789012345678901"]=>
  string(1) "1"
}

array(1) {
  ["1234567890123456789012345678901"]=>
  string(1) "1"
}

This is over a year old? Has anyone been able to fix as I am using latest version of PHP as of 17 Apr 2009 with dynamic queries and just encountered this issue

Many Thanks :-))

In /ext/odbc/php_odbc_includes.h, you can change the 'name' field, of the 'odbc_result_value' struct, from 32 to 256 (or whatever length you need), and then recompile PHP.

With that said, is this (changing 'name' length from 32 to 256) ever going to be a permanent fix in any upcoming official version of PHP?

This same issue is reported in:
