Apache crashed while connecting to MYSQL

I had installed latest WAMP and tried to load a php page which uses a class file.
the class file has code to connect to the Db for fetching records.
When ever the script attempts to make a connection i got the following Error
Window popup in IE and I am not able to do any DB related operation.

Code Sample
-----------------------------------------------------------------
function mysqlConnect(){
//Using Nonpersist connection
$this->_connection=@mysql_connect($this->str_dbServer, $this->str_dbUname, $this->str_dbPass) or $this->returnError("Unable to connect to Database server");
//Using Persist Connection

@mysql_select_db($this->str_dbName,$this->_connection); //Selecting DBASE
}



function mysqlDisconnect(){
// Disconnect the database after dbase access
@mysql_close();
}
----------------------------------------------------------------

How can this be solved?

This is the Err popup message that i got, after this message the browser hangs for few seconds.

Fix to this Issue

This issue is related to the version of PHP. in php version greater that 5, to close a connection we need to specify the connection identifier as its param.

you MUST specify the connection handle.
mysql_close($conenction_handle);

So rewrite the code as

-----------------------------------------------------------------
function mysqlConnect(){
//Using Nonpersist connection
$this->_connection=@mysql_connect($this->str_dbServer, $this->str_dbUname, $this->str_dbPass) or $this->returnError("Unable to connect to Database server");
//Using Persist Connection

@mysql_select_db($this->str_dbName,$this->_connection); //Selecting DBASE
}



function mysqlDisconnect(){
// Disconnect the database after dbase access
@mysql_close($this->_connection);
}
----------------------------------------------------------------

This will work.
