(written in Japanese)1.http://d.hatena.ne.jp/rsky/20071126/11960778602.http://d.hatena.ne.jp/rsky/20071128/11962607323.http://d.hatena.ne.jp/rsky/20071130/1196426672This patch contains two features, anonymous function andsquare bracket array syntax.Anonymous function can be used in loop (does not exhaust memoryas create_function() in loop), work with opcode cachesand also can be called directly like JavaScript's one.For example:% php -r 'print_r(array_map(function($n){ return $n * $n; }, [1, 2, 3]));'Array(    [0] => 1    [1] => 4    [2] => 9)% php -r 'function($str){ echo $str, "\n"; }("foo");'fooMore examples are included in this archive:http://www.opendogs.org/pub/php-5.3dev-071228-anon-patch.zip-- /** * Ryusuke SEKIYAMA * rsky0711@gmail.com */
