RecursiveDirectoryIterator::__construct — Construye un objeto RecursiveDirectoryIterator
$directory, int $flags = FilesystemIterator::KEY_AS_PATHNAME | FilesystemIterator::CURRENT_AS_FILEINFO)Construye un objeto RecursiveDirectoryIterator() para el directorio deseado.
directoryRuta del directorio sobre el cual iterar.
flagsBanderas a pasar para modificar el comportamiento del iterador. Una lista de banderas puede encontrarse en la lista de constantes de FilesystemIterator. También pueden ser especificadas más tarde mediante FilesystemIterator::setFlags()
Se lanza una excepción UnexpectedValueException si el directorio no existe.
Se lanza una excepción ValueError
si directory es una cadena vacía.
| Versión | Descripción |

Ahora se lanza una excepción ValueError
cuando directory es una cadena vacía;
Anteriormente se lanzaba una RuntimeException.

Ejemplo #1 Ejemplo con 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();
}
?>El resultado del ejemplo sería algo similar a:
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.
[EDIT BY danbrown AT php DOT net on 16-JUL-2012: Contains a typofix provided by (lightrekky AT gmail DOT com) in note #109280 on 02-JUL-2012.]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
);
?>
