Problem

When reading ODBC result sets in PHP, column names are truncated to 32 characters

This is not a fault in the driver or communication, but a builtin limitation in the php code.

Solution

Compile PHP from source code after editing file ...<php-dir>/ext/odbc/php_odbc_includes.c:

In "struct odbc_result_value", increase size of "char name[32]" to your needs.
