# Class FilesystemIterator was introduced to have a better DirectoryIterator
# without having to change DirectoryIterator or RecursiveDirectoryIterator.
# On top of FilterIterator the new GlobIterator was introduced. This one allows
# to implement Countable(). But a glob stream flattens all structure, so it
# cannot be derived from RedursiveIterator. With the new structure all children
# of FilesystemIterator have nearly the same behavior. Just their capabilities
# are a bit different. Check out new inheritance tree on SplFileInfo:
#
# [marcus@frodo PHP_5_3]$ php ext/spl/examples/class_tree.php SplFileInfo
# make: `sapi/cli/php' is up to date.
# SplFileInfo
# |-DirectoryIterator (Iterator)
# | \-FilesystemIterator
# | |-GlobIterator (Countable)
# | \-RecursiveDirectoryIterator (RecursiveIterator)
# | \-Phar (ArrayAccess, Countable)
# |-PharFileInfo
# \-SplFileObject (RecursiveIterator, SeekableIterator)
# \-SplTempFileObject
- Fix callable/static mess, the following will now all result in a E_STRICT
. binding a dynamic function as a static callback
. static call of a dynamic function
. is_callable() on a static binding to a dynamic function
# [marcus@frodo PHP_5_3]$ php -a -d error_reporting=8191
# make: `sapi/cli/php' is up to date.
# Interactive shell

# php > class t{ function f() { echo "Funny\n"; } }
# php > $c = array("t","f");
# php > call_user_func($c);

# Strict Standards: call_user_func() expects parameter 1 to be a valid callback, non-static method t::f() cannot be called statically in php shell code on line 1
