Standard PHP Library (SPL)¶
The Standard PHP Library (SPL) is a collection of interfaces and classes that are meant to solve common problems.
SPL offers features, functions, classes and interfaces in many different fields : iterators, data structures, files, exceptions, and observers.
One of the most famous SPL features is the function spl_autoload_register(), which register an autoload handler.
<?php
// SPL and autoloading
spl_autoload_register(function ($class) {
include 'classes/' . $class . '.class.php';
});
if ($object instanceof Countable) {
$count = count($object);
} elseif ($object instanceof Traversable)
$count = iterator_count($object);
} else {
print "Can't count this";
}
?>
