Previous Comments: ------------------------------------------------------------------------ [2010-03-06 12:17:02] kalle@php.net Function call chaining is not supported in any versions of php, its was however decided at the May 2009 PDM to implement it together with array dereferencing in PHP6. ------------------------------------------------------------------------ [2010-02-18 15:02:43] adam dot jorgensen dot za at gmail dot com Description: ------------ When returning an anonymous function from a method or function call, the returned closure is not directly executable in a logical fashion. The closure needs to be stored in order to be executed or must be called via the call_user_func family of functions. This is fairly illogical and inconsistent with the idea of closures. Reproduce code: --------------- function test($a) { return function($b) use($a) { echo $a . ':' . $b . '<br/>'; }; } call_user_func(test(1), 2); $x = test(1); $x(2); test(1)(2); Expected result: ---------------- Output should be: 1:2 1:2 1:2 Actual result: -------------- Execution fails. Error: PHP Parse error: syntax error, unexpected '(' ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=51083&edit=1
