pg_last_error
(PHP 4 >= 4.2.0)
pg_last_error -- Get the last error message string of a
connection
Description
string pg_last_error ( [resource connection])
pg_last_error() returns the last error message for given
connection.
Error messages may be overwritten by internal PostgreSQL(libpq)
function calls. It may not return appropriate error message,
if multiple errors are occurred inside a PostgreSQL module
function.
Use pg_result_error(), pg_result_status() and pg_connection_status()
for better error handling.
Note: This function used to be called pg_errormessage().
See also pg_result_error().
pg_last_notice
(PHP 4 >= 4.0.6)
pg_last_notice -- Returns the last notice message from
PostgreSQL server
Description
string pg_last_notice ( resource connection)
pg_last_notice() returns the last notice message from the
PostgreSQL server specified by connection. The PostgreSQL
server sends notice messages in several cases, e.g. if the
transactions can't be continued. With pg_last_notice(),
you can avoid issuing useless queries, by checking whether
the notice is related to the transaction or not.
Warning
This function is EXPERIMENTAL and it is not fully implemented
yet. pg_last_notice() was added in PHP 4.0.6. However, PHP
4.0.6 has problem with notice message handling. Use of the
PostgreSQL module with PHP 4.0.6 is not recommended even
if you are not using pg_last_notice().
This function is fully implemented in PHP 4.3.0. PHP earlier
than PHP 4.3.0 ignores database connection parameter.
Notice message tracking can be set to optional by setting
1 for pgsql.ignore_notice in php.ini from PHP 4.3.0.
Notice message logging can be set to optional by setting
0 for pgsql.log_notice in php.ini from PHP 4.3.0. Unless
pgsql.ignore_notice is set to 0, notice message cannot be
logged.
