php - Directory iteration using Codeigniter -


i have diirectory containing textfiles,i normaly use directoryiterator class avaialble in php iterate directory , filenames .i've got trouble trying ci. i'm new ci ,so please bear me :).

i've got in default controller named myblog (i wrote function after index function). 

<?php public function diriterate() { $this->load->helper('directory'); $mapi=directory_map('./myfolder/'); $this->load->view('index.php',$mapi); } ?>

and i'm trying in view

<?php foreach($mapi $key) { echo $key; } ?>

am doing plain wrong here ? .

(1) if understanding correct can run mysitename/class/function (in case localhost/myblog/diriterate) (2) directory inside rootfolder (rootfolder/myfolder) there no need of baseurl or ?.

should in view using directoryiterator class or create controller iteration,i'm confused , welcome .thanks in advance.

follow mvc convention.

model models/folder_model.php

class folder_model extends ci_model { function iterate() { $this->load->helper('directory'); $map = directory_map('./myfolder', 1); return $map; } }

for directory map, it'll in root directory of application, meaning path includes index.php. note 1 cause non-recursive , on top-level path.

controller controllers/folder.php

class folder extends ci_controller { function index() { $this->load->model('folder_model'); $map = $this->folder_model->iterate(); $this->load->view('folder', array('map' => $map)); } }

view views/folder.php

<? foreach ($map $item): ?> <?= $item ?> <? endforeach; ?>

this viewable @ http://localhost/index.php/folder.

c++ - Accessing inactive union member and undefined behavior? -

i under impression accessing union member other last 1 set ub, can't seem find solid reference (other answers claiming it's ub without support standard). so, undefined behavior? the confusion c explicitly permits type-punning through union, whereas c++ ( c++11 ) has no such permission. c11 6.5.2.3 structure , union members 95) if member used read contents of union object not same member last used store value in object, appropriate part of object representation of value reinterpreted object representation in new type described in 6.2.6 (a process called ‘‘type punning’’). might trap representation. the situation c++: c++11 9.5 unions [class.union] in union, @ 1 of non-static data members can active @ time, is, value of @ 1 of non-static data members can stored in union @ time. c++ later has language permitting use of unions containing struct s common initial sequences; doesn't permit type-punning. to determine whether union type-punning is allowe...

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.
