The RecursiveTreeIterator class

(PHP 5 >= 5.3.0, PHP 7, PHP 8)

简介

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

$it = new RecursiveArrayIterator(array(1, 2, array(3, 4, array(5, 6, 7), 8), 9, 10));
$tit = new RecursiveTreeIterator($it);

foreach( $tit as $key => $value ){
echo $value . PHP_EOL;
}
