dynamic - PHP incomplete code - scan dir, include only if name starts or end with x -

-

i posted question before yet limited mix code without getting errors.. i'm rather new php :(

( dirs named in series "id_1_1" , "id_1_2", "id_1_3" , "id_2_1" , "id_2_2", "id_2_3" etc.)

i have code, scan directory files , include same known named file each of existing folders.. problem want modify bit code include directories names:

  1. ends "_1"
  2. starts "id_1_"

i want create page load dirs ends "_1" , file load dirs starts "id_1_"..

<?php   include_once "$root/content/common/header.php"; include_once "$root/content/common/header_bc.php"; include_once "$root/content/" . $page_file . "/content.php";  $page_path = ("$root/content/" . $page_file);  $includes = array();  $iterator = new recursiveiteratoriterator(                 new recursivedirectoryiterator($page_path),              recursiveiteratoriterator::self_first);  foreach($iterator $file) {     if($file->isdir()) {         $includes[] = strtoupper($file . '/template.php');     } }  $includes = array_reverse($includes);  foreach($includes $file){    include $file; }  include_once "$root/content/common/footer.php";  ?>

many thanks!

foreach($iterator $file) {     if($file->isdir()) {         // getfilename() gives directory name, when it's um, directory.         $dirname = $file->->getfilename();         if (substr($dirname, 0, 5) === 'id_1_') {             $includes[] = strtoupper($file . '/template.php');         }     } }

there's other ways this, tried add simple functions , logic, in hopes understand it.

ends with like

if (substr($dirname, -2) === '_1')

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
