SYNOPSIS
string pg_last_error ([resource $connection]) DESCRIPTION
pg_last_error(3) 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 multi- ple errors occur inside a PostgreSQL module function. Use pg_result_error(3), pg_result_error_field(3), pg_result_status(3) and pg_connection_status(3) for better error handling. Note This function used to be called pg_errormessage(3). PARAMETERS
o $connection - PostgreSQL database connection resource. When $connection is not present, the default connection is used. The default connection is the last connection made by pg_connect(3) or pg_pconnect(3). RETURN VALUES
A string containing the last error message on the given $connection, or FALSE on error. EXAMPLES
Example #1 pg_last_error(3) example <?php $dbconn = pg_connect("dbname=publisher") or die("Could not connect"); // Query that fails $res = pg_query($dbconn, "select * from doesnotexist"); echo pg_last_error($dbconn); ?> SEE ALSO
