Description:
------------
Compiled PHP 5.2.5 with Apache 2.2.6 with UnixODBC support and other standard options.

ODBC connection was set up using Instantclient version 10.2.0.3 ODBC driver. When tested using isql, the output was OK but when execute using PHP, the fields name truncated to only 15 chars resulting "Undefined Index" notice. This may be a notice but has huge impact on the system.

for example:

SS_SUBJECT_STATUS truncated to SS_SUBJECT_STAT.

Surprisingly, it seems that I'm alone. The closest article i found was field name limited to 30 chars but that is for MSSQL. Setting the defaultlrl also not working as the problem is in the field name, not the content.

Expected result:
----------------
isql output:

SQL> SELECT * FROM SUBJECT_SUMMARY s WHERE s.SS_SEMESTER_CODE='A042' AND s.SS_SUBJECT_CODE='LSI2023' AND s.SS_LECT_GROUP='A'
+-----------------+--------------+----------------+--------------+------------------+------------------+------------------+------------------+------------------+--------------------+--------------------+------------------+
| SS_SEMESTER_CODE| SS_STUDENT_ID| SS_SUBJECT_CODE| SS_LECT_GROUP| SS_TOTAL_CLASS   | SS_ATTEND_COUNT  | SS_LATE_COUNT    | SS_ABSENT_COUNT  | SS_UNKNOWN_COUNT | SS_WARNING_DATE    | SS_BAR_DATE        | SS_SUBJECT_STATUS|
+-----------------+--------------+----------------+--------------+------------------+------------------+------------------+------------------+------------------+--------------------+--------------------+------------------+
| 
+-----------------+--------------+----------------+--------------+------------------+------------------+------------------+------------------+------------------+--------------------+--------------------+------------------+


Actual result:
--------------
php output:

SS_SEMESTER_COD  	SS_STUDENT_ID  	SS_SUBJECT_CODE  	SS_LECT_GROUP  	SS_TOTAL_CLASS  	SS_ATTEND_COUNT  	SS_LATE_COUNT  	SS_ABSENT_COUNT  	SS_UNKNOWN_COUN  	SS_WARNING_DATE  	SS_BAR_DATE  	SS_SUBJECT_STAT
