Constructs a RecursiveDirectoryIterator() for the provided 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().

Exemplos

Exemplo #1 RecursiveDirectoryIterator example

<?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();
}

?>

O exemplo acima irá imprimir algo similar 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
);
?>
