Check DB connection state

Does anyone know how I can check the state of the db connection?

In asp it would be something like this
if(conn.state = 1) then
end if

how would this be done in php?

my DB_DSN looks like this

PHP Code:

---

define('DB_DSN',  'pgsql://phptest:[email protected]/phptest'); 


---

echo connection_status();

will tell you the connection state.

and what is this

define('DB_DSN', 'pgsql://phptest:[email protected]/phptest');


all you did was assign a variable that equals
'pgsql://phptest:[email protected]/phptest'

how is that helping?

yes, I defined a variable that holds my connectionString to the database. It's like assigning the Application("ConnectionString") in a global.asa in asp.

that way all I have to do is

PHP Code:

---

// connects to database
$db = DB::connect(DB_DSN);

// querys the database
$getRecords = $db->query('SELECT * FROM tablename');

// closes connection
$db->disconnect();
