Regarding a "deferment" operator for dvogel at ssc dot wisc dot edu, pick your poison:
<?php
// using ternary operators
function pick($a,$b) { return (isset($a) ? $a : $b); }
$a = (pick($b,$c) ? pick($c,$d) : null);
?>
<?php
// using varargs function
function pick($a) {
$argc = func_num_args();
for ($i = 0; $i < $argc; $i++) {
$arg = func_get_arg($i);
if (! is_null($arg)) {
return $arg;
}
}
return null;
}
$a = pick($b, $c, $d);
?>
