(PHP 4, PHP 5)
pg_dbname — 获得数据库名
$connection
)
pg_dbname() 返回给定 PostgreSQL
connection 资源的数据库名称。如果
connection 不是有效的 PostgreSQL 连接资源则返回 FALSE。
Example #1 pg_dbname() 例子
<?php
error_reporting(E_ALL);
pg_connect("host=localhost port=5432 dbname=mary");
echo pg_dbname(); // mary
?>

This function is as simple as it sounds, it returns the name of the database your are currently connected to on the handle retrieved from a pg_connect() call.
<?php
$pgsql_conn = pg_connect("dbname=mark host=localhost");
if ($pgsql_conn) {
print "Successfully connected to database: " . pg_dbname($pgsql_conn) .
" on " . pg_host($pgsql_conn) . "<br/>\n";
} else {
print pg_last_error($pgsql_conn);
exit;
}
?>

Content-type: text/html
X-Powered-By: PHP/4.3.1
Successfully connected to database: mark on localhost<br/>
Again this function is much more useful when you are changing which database you are connected to in your program.
