(PHP 5 >= 5.1.2)
RecursiveDirectoryIterator::__construct — Constructs a RecursiveDirectoryIterator
$path
[, int $flags = FilesystemIterator::KEY_AS_PATHNAME | FilesystemIterator::CURRENT_AS_FILEINFO
] )
Constructs a RecursiveDirectoryIterator()
for the provided path.
path
The path of the directory to be iterated over.
flags
Flags may be provided which will affect the behavior of some methods. A list of the flags can found under FilesystemIterator predefined constants. They can also be set later with FilesystemIterator::setFlags().
Returns the newly created RecursiveDirectoryIterator.
Throws an UnexpectedValueException
if the path cannot be found or is not a directory.
Example #1 RecursiveDirectoryIterator example
<?php
$directory = '/tmp';
$it = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory));
while($it->valid()) {
if (!$it->isDot()) {
echo 'SubPathName: ' . $it->getSubPathName() . "\n";
echo 'SubPath: ' . $it->getSubPath() . "\n";
echo 'Key: ' . $it->key() . "\n\n";
}
$it->next();
}
?>
以上例程的输出类似于：
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

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
);
?>

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