perl style in php ?

Often I just want to be able to get at a single element from a
function that returns an array. For example, if I just want the
current year I need to write:


$today = getdate();
$year = $today['year'];


Call me lazy but this is two steps to return a single value.
In perl I can nest these two step together into something like:

$year = ( $getdate() )['year'];


I've tried to get several variations of this to work in php but I
don't seem to be having any luck.

Is this style possible in php?

Thanks,

Not quite, although PHP 5 introduces object dereferencing, which comes
close:

<?php

function array2object($array) {
$obj = new stdClass;

foreach ($array as $k => $v) {
$obj->$k = $v;
}

return $obj;
}

$array = array('name' => 'joe');
print array2object($array)->name;

?>

Indexed arrays can be parsed the usual way through the list() function.

No. What I often do in this situation is use extract(). Example:

extract(getdate());
// $year, $mon, $seconds, etc. are now set
