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.

Exemplu 1. list() examples

<?php

$info
= array('coffee', 'brown', 'caffeine');

// Listing all the variables
list($drink, $color, $power) = $info;
print
"$drink is $color and $power makes it special.\n";

// Listing some of them
list($drink, , $power) = $info;
print
"$drink has $power.\n";

// Or let's skip to only the third one
list( , , $power) = $info;
print
"I need $power!\n";

?>

Exemplu 2. An example use of list()

<table>
<tr>
  <th>Employee name</th>
  <th>Salary</th>
