PHP: mssql_close

Description

bool mssql_close ( [resource link_identifier] )

mssql_close() closes the link to a MS SQL Server database that's associated with the specified link identifier. If the link identifier isn't specified, the last opened link is assumed.

Zwraca TRUE w przypadku sukcesu, FALSE w przypadku porażki.

Note that this isn't usually necessary, as non-persistent open links are automatically closed at the end of the script's execution.

mssql_close() will not close persistent links generated by mssql_pconnect().


Please note that on PHP5 this function dont work correct. You have to call it at last two times to make it work.



example:

<?PHP

$query = mssql_query('SELECT * FROM T1'); // query error, T1 object invand

$query = mssql_fetch_row($query);

print_r($query); 



mssql_select_db('DB1', $conn); //db dont exists error



$conn=@mssql_connect('localhost','usr','psw'); //conn success

mssql_select_db('DB1', $conn); //no errors



$query = mssql_query('SELECT * FROM T1'); // no problem, query success

$query = mssql_fetch_row($query);

print_r($query);  // success



echo '<hr>';



mssql_close() or die('failed closing mssql'); // no error!

mssql_select_db('DB2', $conn); //no errors!



$query = mssql_query('SELECT * FROM T2'); // no problem, query success

$query = mssql_fetch_row($query);

print_r($query);  // success



mssql_close() or die('failed closing mssql'); // no error, mssql closed

mssql_select_db('DB2', $conn); //failed, db dont exists



$query = mssql_query('SELECT * FROM T2'); // query error, T2 object invand

$query = mssql_fetch_row($query);

print_r($query);  // failed

?>



so, in fact you have to call mssql_close() two times to shutdown connection..

mssql_close
