Exemple #1 Exemple avec DirectoryIterator::isFile()

Cet exempe va lister tous les fichiers normaux du dossier courant.

<?php
$iterator 
= new DirectoryIterator(dirname(__FILE__));

to actually sort a directoryiterator you need to subclass the iterator and use a comparator function similar to this one

<?php
function cmpSPLFileInfo( $splFileInfo1, $splFileInfo2 )
{
    return
strcmp( $splFileInfo1->getFileName(), $splFileInfo2->getFileName() );
}

class
DirList extends RecursiveDirectoryIterator
{
    private
$dirArray;

    public function
__construct( $p )
    {
       
parent::__construct( $p );
       
$this->dirArray = new ArrayObject();
        foreach(
$this as $item )
        {
           
$this->dirArray->append( $item );
        }
       
$this->dirArray->uasort( "cmpSPLFileInfo" );
    }

    public function
getIterator()
    {
        return
$this->dirArray->getIterator();
    }

}
?>

shows all .jpg files in the current directory but how does the DirectoryIterator sort the output!?

$dir=new DirectoryIterator("./");
foreach ($dir as $file) {
  if ($dir->isDot()) {continue;}    //removes . and ..
    if (strripos($file,".jpg")==true) {
      echo $file . "<br>\n";
    }
}

I put in an example in __autoload, but it is useful here, too...

Yet another class/interface __autoload function. Includes an example usage of the SPL DirectoryIterator class, a settable case-ignore flag, and support for multiple file name patterns to allow easy integration from multiple sources.

<?php
/**
* __autoload
*
* @author Ken Comer
* @copyright released into public domain 2005 Ken Comer
*/

define('IGNORE_CASE',true);
// comment out the define() of IGNORE_CASE to be
//   case-sensitive. I like to ignore case so that I can
//   use UPPERCASE for the test versions of the file.

/**
* autoloads classes and interfaces for PHP5
*
* @author Ken Comer
*/

function __autoload($class_name) {

 
// This will be set the first time through.
  // Put your default values in the place indicated
  //    below so as to eliminate possible duplicates
  //    in the .ini include_path
 
static $possible_path = NULL;
 
// Leave this as NULL.

 
  // List here whatever formats you use for your
  //    file names. Note that, if you autoload
  //    a class that implements a non-loaded interface,
  //    you will also need to autoload that interface.
 
static $permitted_formats = array(
   
"&CLASS.class.inc"
   
,"&CLASS.class.inc.php"
   
,"&CLASS.class.inc.php5"
   
,"class.&CLASS.inc"
   
,"class.&CLASS.inc.php"
   
,"class.&CLASS.inc.php5"
   
,"&CLASS.interface.inc"
   
,"&CLASS.interface.inc.php"
   
,"&CLASS.interface.inc.php5"
   
,"i&CLASS.interface.inc"
   
,"i&CLASS.interface.inc.php"
   
,"i&CLASS.interface.inc.php5"
 
);
 
//  Put the &CLASS wherever the $class_name
  //    might appear

  // Only executed the first time __autoload is called
 
if (NULL===$possible_path):
   
// These are the default paths for this application
   
$possible_path = array_flip(array(
       
"."
       
,".."
       
,"../include"
       
,"/public_html/php/include"
   
));
   
// Customize this yourself, but leave the
    //      array_flip alone. We will use this
    //      to get rid of duplicate entries from the
    //      include_path .ini list.

    // Merge the flipped arrays to get rid of duplicate
    //      "keys" (which are really the valid include
    //      paths) then strip out the keys leaving only
    //      uniques. This is marginally faster than
    //      using array_combine and array_unique and
    //      much more elegant. Okay, it's weird, too.
   
$possible_path = array_keys(array_merge($possible_path,
           
array_flip(explode(ini_get("include_path"),";"))));
  endif;
/* static $possible_path initialization */

 
$possibility = str_replace("&CLASS",$class_name,$permitted_formats);

  foreach (
$possible_path as $directory ) {
    if (!
file_exists($directory) or !is_dir($directory))
    {
      continue;
    }
   
$file_to_check = new DirectoryIterator($directory);

    foreach (
$file_to_check as $file ) {
     
// ignore directories and files that do not contain
      // $class_name
     
if ( !$file->isDir()
          and (
defined(IGNORE_CASE) && TRUE===IGNORE_CASE )
            ?
stripos($file->getFileName(),$class_name)
            :
strpos($file->getFileName(),$class_name) ) :
       
       
// class_name was included, now compare against
        // all permitted file name patterns
       
foreach ( $possibility as $compare ):
            if ((
defined(IGNORE_CASE) && TRUE===IGNORE_CASE )
                ? !
strcasecmp($compare,$file->getFileName())
                :
$compare===$file->getFileName()
            ) {
             
// by using $compare, you will get a qualified
              //    file name
             
include_once($compare);
              return
TRUE;
            }
        endforeach;
/* $possibility */

     
endif;
    }
/* foreach $file_to_check */
 
}
}

Usage:
<?php
//open current directory
$dir = new DirectoryIterator(".");
// use do .. while since we need to iterate atleast once
// and the first two items are always "." and ".."
do  {
   
// if it isn't "." or ".."
   
if (!$dir->isDot()) {
       
// echo out pathname and "/" if it's a directory
       
echo $dir->getPathname() . ($dir->isDir() ? "/" : "");
    }
} while (
$dir->next())
?>

Outputs something like:
/path/file1
/path/dir1/
/path/file2
/path/file3
/path/dir2/

---
Note from the extension author:

Try this:

<?php
foreach(new DirectoryIterator(".") as $file)
{
    if (!
$file->isDot()) {
        echo
$file->getPathname() . ($file->isDir() ? "/" : "");
    }
}
?>
