Edit report at https://bugs.php.net/bug.php?id=18187&edit=1 ID: 18187 Updated by: nikic@php.net Reported by: bram at totalgsm dot net Summary: Consequent implementation of array referencing to user method -Status: Open +Status: Closed Type: Feature/Change Request -Package: Feature/Change Request +Package: *General Issues Operating System: any PHP Version: 4.2.1 -Assigned To: +Assigned To: nikic Block user comment: N Private report: N New Comment: Closing as the $callable() syntax now works for array-callbacks too (as of PHP 5.4). Instead of function_exists the function is_callable can be used. Previous Comments: ------------------------------------------------------------------------ [2002-07-05 11:46:28] bram at totalgsm dot net You support calling user methods using an array in the call_user_func() function. But related functions of call_user_func() don't support the syntax. I would like to see that function_exists could check if the user method exists. The following example code should work: class Foo { function bar($what = 'world') { print 'Hello ' . $what; } } $a_foo = new Foo(); $user_method = array($a_foo, 'bar'); if (!function_exists($user_method)) die('You shouldn\'t see this :)'); $user_method('PHP'); // Should print "Hello PHP" ofcourse. Furthermore the implementation of the user_method calling in call_user_func is incorrect for referencing variabeles, which might be pretty usefull.
