PHP: list() function
PHP: Assign variables as if they were an array
The list() function is used to assign values to a list of variables. Like array(), this is not really a function, but a language construct. list() is used to assign a list of variables in one operation.
Version:
(PHP 4 and above)
Syntax:
list(varname1, varname2.... varnamen )
Parameters:
| Name | Description | Required / Optional |
Type |
|---|---|---|---|
| varname1 | The first variable to be assigned | Required | Mixed* |
| varname2..n | Next variable to be assigned | Optional | Mixed* |
*Mixed : Mixed indicates that a parameter may accept multiple (but not necessarily all) types.
Return value:
The assigned array.
Value Type: Array
Example:
<?php
$w3r1_array = array("php","javascript","asp");
list($x, $y, $z) = $w3r1_array;
echo "We have covered $x, $y and $z.";
$w3r2_array = array("php","javascript","asp");
list($x, , $z) = $w3r2_array;
echo "We have covered $x and $z and so many other topics";
?>
