If i do print_r in PHP, it prints the array in junk

Question

How can I print the array in a Tree-like format--making it easier to read?

Answer 1

Try:

<pre><?php print_r($var); ?></pre>

It will give the proper tree structure that HTML's whitespace policy trims out.

Answer 2

Are you wrapping the output in <pre> tags? That should get you pretty decent output, because it will show the spaces. Another option would be to install the xdebug extension, which then can replace var_dump so that it generates more-readable HTML output.
