You beat me to it Sid :)
Symfony definitely doesn't use the @ suppression operator.
The method appears in a lot of classes - sfRequest, sfDatabase, but they all
are just shortcuts for $sfParameterHolder->get().
Here's the source....
(File: sfParameterHolder.class.php, line 43)
/**
* Retrieves a parameter.
*
* @param string $name A parameter name
* @param mixed $default A default parameter value
*
* @return mixed A parameter value, if the parameter exists, otherwise null
*/
public function & get($name, $default = null)
{
if (array_key_exists($name, $this->parameters))
{
$value = & $this->parameters[$name];
}
else
{
$value = sfToolkit::getArrayValueForPath($this->parameters, $name,
$default);
}
return $value;
}
So you can clearly see, there is no @ operators.
The 'if statement' is a longer way of writing a ternary - both have exactly the
same effect.

Symfony doesn't use @ for retrieving get/post parameter, but uses it
for database connection and other connection type as well as object
chaining, but all these suppress errors are handled/caught somewhere
else (e.g.:write them to log or throw them to browser on dev mode).
