Answer 1

See the RecursiveTreeIterator class

Allows iterating over a RecursiveIterator to generate an ASCII graphic tree.

$treeIterator = new RecursiveTreeIterator(
    new RecursiveDirectoryIterator('/path/to/dir'),
    RecursiveTreeIterator::SELF_FIRST);

foreach($treeIterator as $val) echo $val, PHP_EOL;

Output will be something like this (with c:\php on my machine):

|-c:\php5\cfg
|-c:\php5\data
| |-c:\php5\data\Base
| | \-c:\php5\data\Base\design
| |   |-c:\php5\data\Base\design\class_diagram.png
| |   \-c:\php5\data\Base\design\design.txt
| |-c:\php5\data\ConsoleTools
| | \-c:\php5\data\ConsoleTools\design
| |   |-c:\php5\data\ConsoleTools\design\class_diagram.png
| |   |-c:\php5\data\ConsoleTools\design\console.png
| |   |-c:\php5\data\ConsoleTools\design\console.xml
