I just thought this was a fun and interesting way for lining up method calls and then calling them
back-to-back. Might be useful as a basis for a transactional execution class or something.
<?php
$q = new SplQueue();
$q->setIteratorMode(SplQueue::IT_MODE_DELETE);
$q->enqueue(array("FooBar", "foo"));
$q->enqueue(array("FooBar", "bar"));
$q->enqueue(array("FooBar", "msg", "Hi there!"));
foreach ($q as $task) {
if (count($task) > 2) {
list($class, $method, $args) = $task;
$class::$method($args);
} else {
list($class, $method) = $task;
$class::$method();
}
}
class FooBar {
public static function foo() {
echo "FooBar::foo() called.\n";
}
public static function bar() {
echo "FooBar::bar() called.\n";
}
public static function msg($msg) {
echo "$msg\n";
}
}
?>
Results:
FooBar::foo() called.
FooBar::bar() called.
Hi there!
