note 118254 added to function.array-reduce

So, if you were wondering how to use this where key and value are passed in to the function. I've had success with the following (this example generates formatted html attributes from an associative array of attribute => value pairs): <?php // Attribute List $attribs = [ 'name' => 'first_name', 'value' => 'Edward' ]; // Attribute string formatted for use inside HTML element $formatted_attribs = array_reduce( array_keys($attribs), // We pass in the array_keys instead of the array here function ($carry, $key) use ($attribs) { // ... then we 'use' the actual array here return $carry . ' ' . $key . '="' . htmlspecialchars( $attribs[$key] ) . '"'; }, '' ); echo $formatted_attribs; ?> This will output: name="first_name" value="Edward" ---- Server IP: 72.52.91.14 Probable Submitter: 68.97.17.89 ---- Manual Page -- http://php.net/manual/en/function.array-reduce.php Edit -- https://master.php.net/note/edit/118254 Del: integrated -- https://master.php.net/note/delete/118254/integrated Del: useless -- https://master.php.net/note/delete/118254/useless Del: bad code -- https://master.php.net/note/delete/118254/bad+code Del: spam -- https://master.php.net/note/delete/118254/spam Del: non-english -- https://master.php.net/note/delete/118254/non-english Del: in docs -- https://master.php.net/note/delete/118254/in+docs Del: other reasons-- https://master.php.net/note/delete/118254 Reject -- https://master.php.net/note/reject/118254 Search -- https://master.php.net/manage/user-notes.php
