PHP : Function Reference : PostgreSQL Functions : pg_close

pg_close

Closes a PostgreSQL connection (PHP 4, PHP 5)
bool pg_close ( [resource connection] )

pg_close() closes the non-persistent connection to a PostgreSQL database associated with the given connection resource.

Note:

Using pg_close() is not usually necessary, as non-persistent open connections are automatically closed at the end of the script.

If there is open large object resource on the connection, do not close the connection before closing all large object resources.

Parameters

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() or pg_pconnect().

Return Values

Returns TRUE on success or FALSE on failure.

Examples

Example 1905. pg_close() example

<?php
$dbconn
= pg_connect("host=localhost port=5432 dbname=mary")
  or die(
"Could not connect");
echo
"Connected successfully";
pg_close($dbconn);
?>

The above example will output:

Connected successfully

Code Examples / Notes » pg_close

mark

This function closes the current database connection specified by a handle returned from a pg_connect() call.
<?php
   $pgsql_conn = pg_connect("dbname=mark host=localhost");
   if ($pgsql_conn) {
       print "Successfully connected to: " . pg_host($pgsql_conn) . "<br/>\n";
   } else {
       print pg_last_error($pgsql_conn);
       exit;
   }
   // Do database stuff here.
   if(!pg_close($pgsql_conn)) {
       print "Failed to close connection to " . pg_host($pgsql_conn) . ": " .
      pg_last_error($pgsql_conn) . "<br/>\n";
   } else {
       print "Successfully disconnected from database";
   }
?>
Of course you normally wouldn't print a message.  
Regards, --mark

pg_close(...) will not technically close a persistent connection but instead returns it back to the connection pool thus giving you the desired effect of having the connection closed within your script.
