note 83945 added to function.str-replace

I always miss interpolate functionality in PHP, so I wrote this little helper method. It allows you to specify your own markup using $prefix and $postfix. <?php # Interpolate a string using hash. # by Maxim Chernyak ( http://mediumexposure.com ) function interpolate($template, $hash, $prefix = '#{', $postfix = '}' ) { $tokenize = create_function('$token', 'return "'. $prefix .'".$token."'.$postfix.'";'); $keys = array_keys($hash); $values = array_values($hash); $keys = array_map($tokenize, $keys); return str_replace($keys, $values, $template); } ?> For example: <?php $result = interpolate('Hello, #{username}. Welcome to #{site}.', array('username' => 'Hakunin', 'site' => 'php.net')); ?> ---- Server IP: 209.41.74.194 Probable Submitter: 209.10.106.40 ---- Manual Page -- http://www.php.net/manual/en/function.str-replace.php Edit -- https://master.php.net/note/edit/83945 Del: integrated -- https://master.php.net/note/delete/83945/integrated Del: useless -- https://master.php.net/note/delete/83945/useless Del: bad code -- https://master.php.net/note/delete/83945/bad+code Del: spam -- https://master.php.net/note/delete/83945/spam Del: non-english -- https://master.php.net/note/delete/83945/non-english Del: in docs -- https://master.php.net/note/delete/83945/in+docs Del: other reasons-- https://master.php.net/note/delete/83945 Reject -- https://master.php.net/note/reject/83945 Search -- https://master.php.net/manage/user-notes.php
