returning multiple arrays

[stijn0713]

I call a method and i want to return more then one value. this can be done in several ways, i've seen some like

 

$x = $a . "|" . $b . "|" . $c;

return $x;

 

and then using explode where you invoke the method.

 

This trick worked for me untill i wanted to return 3 arrays.

 

After exploding the arrays by |, i cannot use them anymore, e.g. i cannot f.e. print_r them. I will only display 'array'.

 

I guess this has something to do with call by reference / call by value.

 

Could somebody explain it more precisely ?

 

Thanks

Firstly, if your function needs to return more than one value your likely doing too much within the function.

 

Anyway, just return the arrays within an array.

 

return array($a, $b, $c);
