note 84584 added to function.str-replace

I've never seen it called interpolate before, but on a whim I decided to make another one-liner for myself. Somehow it turned out very much like Max's version. jaimthorn, your version also uses array_keys and array_values, which is basically like the other half of Max's function. I only used array_map because it returns the input array, unlike array_walk, both of which are doing the same thing (evaluating elements of array against a provided function). And if you don't think create_function is used a lot, head over to any of the functional languages, where anonymous functions are an integral part of the language, or even to Javascript, where every second line looks like this: var THAT = function () { /* code goes here */ } Anyhow, to the one-liner: (test.tmpl) hello %abc% replace %def% lol <?php $test = array("abc" => 9000, "def" => "hello?"); function _tmpl($arr, $tmpl) { return str_replace(array_map(create_function('$a', 'return "%$a%";'), array_keys($arr)), array_values($arr), file_get_contents($tmpl)); } ?> ---- Server IP: 219.94.145.73 Probable Submitter: 122.17.129.25 ---- Manual Page -- http://www.php.net/manual/en/function.str-replace.php Edit -- https://master.php.net/note/edit/84584 Del: integrated -- https://master.php.net/note/delete/84584/integrated Del: useless -- https://master.php.net/note/delete/84584/useless Del: bad code -- https://master.php.net/note/delete/84584/bad+code Del: spam -- https://master.php.net/note/delete/84584/spam Del: non-english -- https://master.php.net/note/delete/84584/non-english Del: in docs -- https://master.php.net/note/delete/84584/in+docs Del: other reasons-- https://master.php.net/note/delete/84584 Reject -- https://master.php.net/note/reject/84584 Search -- https://master.php.net/manage/user-notes.php
