pg_last_error
(PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)
pg_last_error — Get the last error message string of a connection
Description
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
connectionisnull, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect().WarningAs of PHP 8.1.0, using the default connection is deprecated.
Return Values
A string containing the last error message on the
given connection.
