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

kod:<pre style="font-size:x-small; font-family: monospace;"><?php
$info = array(´coffee´, ´brown´, ´caffeine´);
// Listing all the variables
list($drink, $color, $power) = $info;
print "$drink is $color and $power makes it special.
";
// Listing some of them
list($drink, , $power) = $info;
print "$drink has $power.
";
// Or let´s skip to only the third one
list( , , $power) = $info;
print "I need $power!
";
?></pre>
list() är härligt, eller hur?
