1.2.634. List With Reference¶
Support for references in list calls is not backward compatible with older versions of PHP. The support was introduced in PHP 7.3.
<?php
$array = [1,2,3];
[$c, &$d, $e] = $a;
$d++;
$c++;
print_r($array);
/*
displays
Array
(
[0] => 1 // Not a reference to $c, unchanged
[1] => 3 // Reference from $d
[2] => 3
)
*/
?>
