Name of the table from which to select rows.


An array whose keys are field names in the table table_name, and whose values are the conditions that a row must meet to be retrieved.


Any number of PGSQL_CONV_FORCE_NULL, PGSQL_DML_NO_CONV, PGSQL_DML_EXEC, PGSQL_DML_ASYNC or PGSQL_DML_STRING combined. If PGSQL_DML_STRING is part of the options then query string is returned.

Example 1971. pg_select() example

= pg_connect('dbname=foo');
// This is safe, since $_POST is converted automatically
$rec = pg_select($db, 'post_log', $_POST);
 if (
$rec) {
"Records selected\n";
 } else {
"User must have sent wrong inputs\n";
