If I use placeholders (?) in a SELECT statement using odbc_prepare() and odbc_execute(), I get gibberish from the MySQL driver and it works correctly using the PostgreSQL driver.

If I change the query to "WHERE id=1", it works fine.  UPDATES using placeholders work fine for MySQL.

I am able to do the same queries in C using the same libraries for unixODBC and MyODBC (and postgres-odbc) and get correct results.  This may not be a PHP and/or PHP-odbc problem, but so far, it looks that way.

I get substantially the same results on an FC3 and a RH9 linux box with the following versions:

FC3:  php-4.3.10-3.2, php-odbc-4.3.10-3.2, unixODBC-2.2.9-1, MyODBC-2.50.39-19.1, mysql-3.23.58-14

RH9:  php-4.2.2-17, php-odbc-4.2.2-17, unixODBC-2.2.3-6, MyODBC-2.50.39-11, mysql-3.23.54a-11

Reproduce code:
$conn = odbc_connect('tstdb', 'xxxxx', 'yyyyy');
if ($conn == 0) {
    echo("connect failed");
    $sqlerr = odbc_errormsg($conn);
$stmt = odbc_prepare($conn, 'SELECT firstname, lastname FROM tst where id=?');
$result = odbc_execute($stmt, array(1));
if (!$result) {
    echo("SELECT failed");
    $sqlerr = odbc_errormsg($conn);
while (odbc_fetch_into($stmt, $row)) {
    print $row[0] . " " . $row[1] . "\n";   

Expected result:
I expect to get the firstname and lastname from the database.  The table is an int id and varchar(20) for the names.

Actual result:
Some kind of junk:  "std n_u"

Postgres gives the correct result (firstname and lastname from the database)

got a newer version of the tgz file this morning, built it successfully (using ./configure --with-unixODBC=shared,/usr) and ran it like so:

[jake@anhinga php4-STABLE-200504131242]$ php -dextension_dir=`pwd`/ext ~/x.php

and got exactly the same results as before (correct from pgsql, junk (n_u nT0) from mysql)

I have also run into another problem, which may be related in that php-odbc does not seem to do quoting correctly for placeholders for either pgsql or mysql ... not sure if i should file a different bug or add it to this one ... it also occurs on this version of php

Are you sure this isn't a bug with the Mysql ODBC driver?
