in the following php what does the '@' sign do:

1 )

Code: Select all

if(@$_SESSION['login'] !== true) {
 ...
}
2 )

Code: Select all

@ini_set('session.use_trans_sid', 0);
3 )

Code: Select all

@ob_start();
what is the difference if it was not in these examples?

thanks

thanks, that makes sense

similarly, what does this '&' sign do?

Code: Select all

if (!isset($this->globalvariables))
{
 require_once(cms_join_path(dirname(__FILE__), 'class.globalvariables.inc.php'));
 $globalvariables =[color=#FF0000]&[/color] new GlobalVariables();
 $this->globalvariables = [color=#FF0000]&[/color]$globalvariables;
}
