Yes. PHP4 or PHP5? What have you tried already?

i tried like other languages. This is an example.
PHP5

class emr
{
function __construct($us ername)
{
}
function __construct($us ername, $password)
{
}
function __construct($us ername, $password, $name)
{
}
}
Then i have that error:Fatal error: Cannot redeclare emr::__construc t()

See my reply in alt.comp.lang.p hp; in short: Overloading like in Java is not
supported in PHP.

If that's what you wnat, why not declare some defaults for the variables:
function __construct($us ername, $password=false , $name=false)
{
if($name!==fals e)//execute some code
if($password!== false)//domething else
}
Etc.
Which makes you able to:
$a = new emr('username') ;

And all arguments left out will result in their default values.

Else, it's up to the earlier mentioned func_get_args() ;

Grtz,
