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";
}
$it->next();
}
?>Résultat de l'exemple ci-dessus est similaire à :
SubPathName: fruit/apple.xml SubPath: fruit Key: /tmp/fruit/apple.xml SubPathName: stuff.xml SubPath: Key: /tmp/stuff.xml SubPathName: veggies/carrot.xml SubPath: veggies Key: /tmp/veggies/carrot.xml
You can use RecursiveDirectoryIterator::FOLLOW_SYMLINKS as a flag to the constructor to have RecursiveDirectoryIterator follow symlinks, which it does not do by default.
[EDIT BY danbrown AT php DOT net on 16-JUL-2012: Contains a typofix provided by (lightrekky AT gmail DOT com) in note #109280 on 02-JUL-2012.]The two default flags are zero (virtual) as with my PHP versions (5.3 and 5.4). Which means you can not check if those are set or not with the & bitwise operator:<?php// CURRENT_AS_FILEINFO (0)// KEY_AS_PATHNAME (0)### always FALSE ###$directoryIterator->getFlags() & RecursiveDirectoryIterator::CURRENT_AS_FILEINFO;?>But this also allows that you can use other flags right ahead without repeating the default ones:<?phpnew 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:<?phpnew RecursiveDirectoryIterator( '.', FilesystemIterator::SKIP_DOTS | FilesystemIterator::UNIX_PATHS);?>
