function debug
Same name in other branches
- 7.x includes/common.inc \debug()
- 8.9.x core/includes/common.inc \debug()
Outputs debug information.
The debug information is passed on to trigger_error() after being converted to a string using print_r() or var_export().
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.
Deprecated
in drupal:9.2.0 and is removed from drupal:10.0.0. Use dump() instead.
