Need help with if(isset($variable))

General PHP Help
#1

Hey guys, I’m trying to set some variables to exclude people from an array.

So,
[php] if(isset($_SESSION[‘person1’])){
$_SESSION[‘person2’] = $person;
}else{
$_SESSION[‘person1’] = $person;
}

if(isset($_SESSION['person1'] && $_SESSION['person2'])){
	$_SESSION['person3'] = $person;
		}
if(isset($_SESSION['person1'] && $_SESSION['person2'] && $_SESSION['person3'])){
	$_SESSION['person4'] = $person;
		}
if(isset($_SESSION['person1'] && $_SESSION['person2'] && $_SESSION['person3'])){
	$_SESSION['person4'] = $person;
		}
if(isset($_SESSION['person1'] && $_SESSION['person2'] && $_SESSION['person3'] && $_SESSION['person4'])){
	$_SESSION['person5'] = $person;
		}
if(isset($_SESSION['person1'] && $_SESSION['person2'] && $_SESSION['person3'] && $_SESSION['person4'] && $_SESSION['person5'])){
	$_SESSION['person6'] = $person;
		}
if(isset($_SESSION['person1'] && $_SESSION['person2'] && $_SESSION['person3'] && $_SESSION['person4'] && $_SESSION['person5'] && $_SESSION['person56'])){
	$_SESSION['person7'] = $person;
		}
if(isset($_SESSION['person1'] && $_SESSION['person2'] && $_SESSION['person3'] && $_SESSION['person4'] && $_SESSION['person5'] && $_SESSION['person6'] && $_SESSION['person7'])){
	$_SESSION['person8'] = $person;
		}
if(isset($_SESSION['person1'] && $_SESSION['person2'] && $_SESSION['person3'] && $_SESSION['person4'] && $_SESSION['person5'] && $_SESSION['person6'] && $_SESSION['person7'] && $_SESSION['person8'])){
	$_SESSION['person9'] = $person;
		}
if(isset($_SESSION['person1'] && $_SESSION['person2'] && $_SESSION['person3'] && $_SESSION['person4'] && $_SESSION['person5'] && $_SESSION['person6'] && $_SESSION['person7'] && $_SESSION['person8'] && $_SESSION['person9'])){
	$_SESSION['person10'] = $person;
		}
if(isset($_SESSION['person1'] && $_SESSION['person2'] && $_SESSION['person3'] && $_SESSION['person4'] && $_SESSION['person5'] && $_SESSION['person6'] && $_SESSION['person7'] && $_SESSION['person8'] && $_SESSION['person9'] && $_SESSION['person10'])){
	$_SESSION['person11'] = $person;
		}[/php]

So I want it to check person 1 then 2 then 3 then 4 and set them in order.
So if #1 isnt set it sets #2, if #1 and #2 is set it sets #3, it #1 and #2 and #3 is set it sets #4 etc… etc…

Is there any easier way to do this? or have I got it correct?

Damn, can’t edit it anymore. Here is updated code.

[php] if(isset($_SESSION[‘person1’])){
if(isset($_SESSION[‘person2’])){
}else{
$_SESSION[‘person2’] = $person;
}
}else{
$_SESSION[‘person1’] = $person;
}

if(isset($_SESSION['person1']) && isset($_SESSION['person2'])){
	$_SESSION['person3'] = $person;
	$this->getRandomPerson($boardpoint,$task,$n);
		}
if(isset($_SESSION['person1']) && isset($_SESSION['person2']) && isset($_SESSION['person3'])){
	$_SESSION['person4'] = $person;
		}
if(isset($_SESSION['person1']) && isset($_SESSION['person2']) && isset($_SESSION['person3']) && isset($_SESSION['person4'])){
	$_SESSION['person5'] = $person;
		}
if(isset($_SESSION['person1']) && isset($_SESSION['person2']) && isset($_SESSION['person3']) && isset($_SESSION['person4']) && isset($_SESSION['person5'])){
	$_SESSION['person6'] = $person;
		}
if(isset($_SESSION['person1']) && isset($_SESSION['person2']) && isset($_SESSION['person3']) && isset($_SESSION['person4']) && isset($_SESSION['person5']) && isset($_SESSION['person6'])){
	$_SESSION['person7'] = $person;
		}
if(isset($_SESSION['person1']) && isset($_SESSION['person2']) && isset($_SESSION['person3']) && isset($_SESSION['person4']) && isset($_SESSION['person5']) && isset($_SESSION['person6']) && isset($_SESSION['person7'])){
	$_SESSION['person8'] = $person;
		}
if(isset($_SESSION['person1']) && isset($_SESSION['person2']) && isset($_SESSION['person3']) && isset($_SESSION['person4']) && isset($_SESSION['person5']) && isset($_SESSION['person6']) && isset($_SESSION['person7']) && isset($_SESSION['person8'])){
	$_SESSION['person9'] = $person;
		}
if(isset($_SESSION['person1']) && isset($_SESSION['person2']) && isset($_SESSION['person3']) && isset($_SESSION['person4']) && isset($_SESSION['person5']) && isset($_SESSION['person6']) && isset($_SESSION['person7']) && isset($_SESSION['person8']) && isset($_SESSION['person9'])){
	$_SESSION['person10'] = $person;
		}
if(isset($_SESSION['person1']) && isset($_SESSION['person2']) && isset($_SESSION['person3']) && isset($_SESSION['person4']) && isset($_SESSION['person5']) && isset($_SESSION['person6']) && isset($_SESSION['person7']) && isset($_SESSION['person8']) && isset($_SESSION['person9']) && isset($_SESSION['person10'])){
	$_SESSION['person11'] = $person;
		}[/php]

Because what I’m trying to do is,
Build an array with people.
Select a random person.
Check persons suitability, if fail - Set $_SESSION[‘person’]
Build an array with people.
Remove any $_SESSION[‘person’]
Rebuild array.
Select a random person.
Check persons suitability, if true - add to database.
I’m really stuck…

Heres everything…

Thankyou for those who viewed my problem. But I’ve sorted it ;D

Instead of using sessions, I used a temporary field in the database.
Set it to yes if person is selected.
Build an array with people who are ‘yes’
Select a random person.
Check persons suitability, if fail - temporary field in the database to ‘no’.
Rinse repeat until someone is found or, if($len == 0){ ERROR

Much easier.
Then with each job processed it resets the temporary field in the database if person is selected.

WOOOO!
