Using IBM DB2 V7.1 and MS SQL Server 7 ODBC database connections.
Print the result of odbc_error() or odbc_errormsg() after each call to an odbc_ function that gives no error and, sooner or later, you'll get garbage instead of a blank string!

On persistent connections, a  failed T-SQL will allow odbc_error and odbc_errormsg to return the error, but a subsequent successful T-SQL will not clear the error.  Is it a bug?

If you use an argument, make sure its the CONNECTION_ID and not the RESULT_ID.

Testing the result can return a null string or sometimes a garbage string.

# -- Example code  --
$rs = odbc_exec($dbc, $sql);

#this is wrong but won't error out until
#you demo the page for a client!
  if (odbc_error($rs)) die(...);

#these work
  if (odbc_error()) die(...);
  if (odbc_error($dbc)) die(...);

I have use this function, its very simple and cute.
with IBM DB2
<?php
        
// you must set the connection first
        
if (odbc_error())
         {
               echo
odbc_errormsg($conn);
         }
        
// if you want to show the perfect error message
         // then format it using string functions.
?>
Have a good day!
