RecursiveDirectoryIterator::__construct — Construit un objet RecursiveDirectoryIterator

Description

public RecursiveDirectoryIterator::__construct(string $directory, int $flags = FilesystemIterator::KEY_AS_PATHNAME | FilesystemIterator::CURRENT_AS_FILEINFO)

Construit un objet RecursiveDirectoryIterator() concernant le dossier souhaité.

Liste de paramètres

directory: Chemin du dossier sur lequel itérer.
flags: Drapeaux à passer pour changer le comportement de l'itérateur. Une liste de drapeaux peut être trouvée dans la liste des constantes de FilesystemIterator. Elles peuvent aussi être renseignées plus tard au moyen de FilesystemIterator::setFlags()

Erreurs / Exceptions

Lance une exception UnexpectedValueException si le répertoire n'existe pas.

Lance une exception ValueError si directory est une chaîne vide.

Historique

Version	Description
8.0.0	Lance désormais une exception ValueError quand `directory` est une chaîne vide ; Auparavant, une RuntimeException était lancée.

Exemples

Exemple #1 Exemple avec RecursiveDirectoryIterator

<?php

$directory = '/tmp';

$it = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory));

$it->rewind();
while($it->valid()) {

    if (!$it->isDot()) {
        echo 'SubPathName: ' . $it->getSubPathName() . "\n";
        echo 'SubPath:     ' . $it->getSubPath() . "\n";
        echo 'Key:         ' . $it->key() . "\n\n";
    }

    $it->next();
}

?>

Résultat de l'exemple ci-dessus est similaire à :

SubPathName: fruit/apple.xml
SubPath:     fruit
Key:         /tmp/fruit/apple.xml

SubPathName: stuff.xml
SubPath:     
Key:         /tmp/stuff.xml

SubPathName: veggies/carrot.xml
SubPath:     veggies
Key:         /tmp/veggies/carrot.xml

You can use RecursiveDirectoryIterator::FOLLOW_SYMLINKS as a flag to the constructor to have RecursiveDirectoryIterator follow symlinks, which it does not do by default.

The two default flags are zero (virtual) as with my PHP versions (5.3 and 5.4). Which means you can not check if those are set or not with the & bitwise operator:

<?php
// CURRENT_AS_FILEINFO (0)
// KEY_AS_PATHNAME (0)

### always FALSE ###
$directoryIterator->getFlags() & RecursiveDirectoryIterator::CURRENT_AS_FILEINFO;

?>

But this also allows that you can use other flags right ahead without repeating the default ones:

<?php
new RecursiveDirectoryIterator(
    '.', 
    FilesystemIterator::UNIX_PATHS
);
?>

There is no need to repeat the default flags. Please note that this is different to FilesystemIterator which has as well the SKIP_DOTS flag as default which is non-zero:

<?php
new RecursiveDirectoryIterator(
    '.', 
    FilesystemIterator::SKIP_DOTS
        | FilesystemIterator::UNIX_PATHS
);
?>
