<?php
# Another attempt at named args (perl-inspired):
# list_to_assoc('key', 'value', 'key', 'value', ...) =>
# pairs[]
function list_to_assoc() {
$list = func_get_args();
$assoc = array();
while ($list and count($list) > 1) {
$assoc[array_shift($list)] = array_shift($list);
}
if ($list) { $assoc[] = $list[0]; }
return $assoc;
}
# Usage:
function example($required) {
$args = func_get_args(); array_shift($args); # drop 'required'
$rest = list_to_assoc($args);
echo "$required\n" . $rest['comment'];
}
?>
example("This is required...",
'comment', 'this is not.'); # this is like 'comment' =>
'this is not'
