note 105634 added to functions.anonymous

As already noted in the documentation, the 5.4 alpha releases reintroduce $this back into anonymous functions; note that it is bound early and refers to the object scope in which the function created it (in contrast with, say, JavaScript, where it refers to the scope in which the function is called). So <?php class test1 { private $foo = "This is Class One"; public function make_anonymous_function() { return function() { echo $this->foo; }; } } class test2 { private $foo = "This is Class Two"; public function use_anonymous_function() { $t1 = new test1; $func = $t1->make_anonymous_function(); echo $func(); } } $t2 = new test2; $t2->use_anonymous_function(); ?> outputs "This is Class One". ---- Server IP: 69.147.83.197 Probable Submitter: 125.237.147.185 ---- Manual Page -- http://www.php.net/manual/en/functions.anonymous.php Edit -- https://master.php.net/note/edit/105634 Del: integrated -- https://master.php.net/note/delete/105634/integrated Del: useless -- https://master.php.net/note/delete/105634/useless Del: bad code -- https://master.php.net/note/delete/105634/bad+code Del: spam -- https://master.php.net/note/delete/105634/spam Del: non-english -- https://master.php.net/note/delete/105634/non-english Del: in docs -- https://master.php.net/note/delete/105634/in+docs Del: other reasons-- https://master.php.net/note/delete/105634 Reject -- https://master.php.net/note/reject/105634 Search -- https://master.php.net/manage/user-notes.php
