What the does list () do?!

amitrus

Been trying to understand someone else's script all day long. Ran into the list() function and the PHP manual has been no help. Can someone put it fairly simply? with an example maybe?

(you could send it to the "user Contributed Notes" in the PHP manual and make a good contribution)

Thanks,

list() takes a list of individual variables (aka 'scalar' variables) and presents them as if they were the successive elements of an array. I find it mostly useful when retrieving from a database: instead of putting the results into an array:

$data = pg_fetch_row($qry);
echo $data['name'] . ;
echo $data['address'] . ;
...

you can just say:

list($name,$address) = pg_fetch_row($qry);
echo $name . ;
echo $address . ;
