The syntactic-sugar form isn't there with the @, but it can still be done in a single line.

<?php

// DEFINE DECORATOR

$decoratorFunction = function($orig) { print "decorating $orig"; return function() use ($orig) { $params = func_get_args(); print "\nCalling a function with: " . count($params) . " arguments"; return call_user_func_array($orig, $params); }; };

// DEFINE A FUNCTION TO DECORATE

function someFunction($a, $b) { return $a + $b; }

// CREATE NEW DECORATED FUNCTION(s)

$decorated = $decoratorFunction("someFunction");

$decorated2 = $decoratorFunction("printf");

echo "\noutput: " . $decorated(1,2);

echo "\nOutput: " . $decorated2("\n%s", "cool"); }
