db2_conn_errormsg — Returns the last connection error message and SQLCODE value
$connection
] ) : string
db2_conn_errormsg() returns an error message and SQLCODE
value representing the reason the last database connection attempt failed.
As db2_connect() returns FALSE in the event of a failed
connection attempt, do not pass any parameters to
db2_conn_errormsg() to retrieve the associated error
message and SQLCODE value.
If, however, the connection was successful but becomes invalid over time,
you can pass the connection parameter to retrieve
the associated error message and SQLCODE value for a specific connection.
connectionA connection resource associated with a connection that initially succeeded, but which over time became invalid.
Returns a string containing the error message and SQLCODE value resulting from a failed connection attempt. If there is no error associated with the last connection attempt, db2_conn_errormsg() returns an empty string.
Example #1 Retrieving the error message returned by a failed connection attempt
The following example demonstrates how to return an error message and SQLCODE value after deliberately passing invalid parameters to db2_connect().
<?php
$conn = db2_connect('badname', 'baduser', 'badpassword');
if (!$conn) {
print db2_conn_errormsg();
}
?>
