note 112192 added to functions.anonymous

One item not mentioned anywhere is how to invoke an anonymous function "in-line". To explain what I mean, let me use an actual example. Instead of creating code like this: <?php $wording = ($from == 0 && $to == 0 ? '< 1 Year' : ($to == 9999 ? ($from - 1) . '+ Years' : "$from - $to Years")); ?> You might, instead, want to use an anonymous function right in the assignment line. However, doing: <?php $wording = function() use ($from, $to) { ... } ?> would actually assign $wording to the Closure instance, not actually execute the function. The best way to do this that I've found is: <?php $wording = call_user_func(function() use ($from, $to) { if ($from == 0 && $to == 0) return '< 1 Year'; if ($to == 9999) return ($from - 1) . '+ Years'; return "$from - $to Years"; }); ?> It's a little longer than the first code sample, but I think it's more readable, and using this methodology opens up the ability to use more complex means of calculating a value without filling the variable scope with a bunch of temporary variables. ---- Server IP: 69.147.83.199 Probable Submitter: 184.71.0.166 ---- Manual Page -- http://php.net/manual/en/functions.anonymous.php Edit -- https://master.php.net/note/edit/112192 Del: integrated -- https://master.php.net/note/delete/112192/integrated Del: useless -- https://master.php.net/note/delete/112192/useless Del: bad code -- https://master.php.net/note/delete/112192/bad+code Del: spam -- https://master.php.net/note/delete/112192/spam Del: non-english -- https://master.php.net/note/delete/112192/non-english Del: in docs -- https://master.php.net/note/delete/112192/in+docs Del: other reasons-- https://master.php.net/note/delete/112192 Reject -- https://master.php.net/note/reject/112192 Search -- https://master.php.net/manage/user-notes.php
