How to recursively return the anonymous function in PHP

PHP 5.2 Added the function of anonymous function, but I found the problem when the anonymous function recursion

 
  0) {        return $test ($a);    }}; $test (10);

As shown in the code above, I want to $test invoke it myself recursively in this anonymous function, but I find that it appears after the call.

Fatal error:function Name must be a string in/library/webserver/documents/test.php on line 9

That is $test , this variable is not recognized, can we have a way to recursively function in the anonymous function itself?

Need to pass $test as a reference with order for it

$test = function ($a) use (& $test) {    ...}

Tips:google helps.

php5.4 down through

$test = NULL, $test = function ($a) use (& $test) {    echo $a;    $a--;    if ($a > 0) {        return $test ($a);    }}; $test (10);
