Test script: --------------- <? $dbq = "test.mdb"; $sql = "SELECT * FROM table1"; $pdo = new PDO("odbc:Driver={Microsoft Access Driver (*.mdb)};Dbq=$dbq;"); $result = $pdo->query($sql,PDO::FETCH_ASSOC); foreach ($result as $row) { echo $row['COMMENT'] . "\n"; } ?> Expected result: ---------------- the script should return whatever chars are in the memo field, up to 65536 max. instead it only handles 255 chars as if it were a text field. Actual result: -------------- between 256 and 259 returns scrambled data. at 260 gives "zend mm heap corrupted". a 261 CLI blows up. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62215&edit=1
