pg_last_error
pg_last_error returns the last error message for a given connection.
Error messages may be overwritten by internal PostgreSQL (libpq) function calls. It may not return an appropriate error message if multiple errors occur inside a PostgreSQL module function.
Use pg_result_error, pg_result_error_field, pg_result_status and pg_connection_status for better error handling.
Note:
This function used to be called pg_errormessage.
Parameters
- connection
-
An PgSql\Connection instance. When connection is null, the default connection is used. The default connection is the last connection made by pg_connect or pg_pconnect.
Warning:
As of PHP 8.1.0, using the default connection is deprecated.
Return Values
A string containing the last error message on the given connection.
