print_r in drupal_set_message

This example will print our human readable information about the $_SESSION inside a drupal_set_message. You can replace the $_SESSION with any other variable or array (or object).

  1. drupal_set_message('<pre>'. print_r($_SESSION, true) .'</pre>');


I think the Drupal code standards always has TRUE/FALSE in uppercase. I know both work but when checking my work with the coder module I don't like it to complain about little things.

I use this technique to figure out what's up very often. Usually to make sure what should be there is.

Just what I needed. Thanks.
