function debug in Zircon Profile 8.0

Same name and namespace in other branches

1. 8 core/includes/common.inc \debug()

Outputs debug information.

The debug information is passed on to trigger_error() after being converted to a string using _drupal_debug_message().

Parameters

$data: Data to be output.

$label: Label to prefix the data.

$print_r: Flag to switch between print_r() and var_export() for data conversion to string. Set $print_r to FALSE to use var_export() instead of print_r(). Passing recursive data structures to var_export() will generate an error.
