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.


(PHP 4 and above)


list(varname1, varname2.... varnamen )


Name Description Required /
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


$w3r1_array = array("php","javascript","asp");
list($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";


We have covered php, javascript and asp.We have covered php and asp and so many other topics

PHP: Tips of the Day

PHP: How to generate a random, unique, alphanumeric string for use in a secret link?

Security Notice: This solution should not be used in situations where the quality of your randomness can affect the security of an application. In particular, rand() and uniqid() are not cryptographically secure random number generators. See Scott's answer for a secure alternative.

If you do not need it to be absolutely unique over time:

md5(uniqid(rand(), true))

Otherwise (given you have already determined a unique login for your user):

md5(uniqid($your_user_login, true))
