list
(PHP 3, PHP 4, PHP 5 )
list --
Assign variables as if they were an array
Description
void
list ( mixed ...)
Like array(), this is not really a function,
but a language construct. list() is used to
assign a list of variables in one operation.
Notã:
list() only works on numerical arrays and assumes
the numerical indices start at 0.
