The nuDebug() function is a PHP utility that helps developers debug their applications by logging information during code execution.

It accepts multiple types of inputs—such as strings, arrays, or objects—and writes them to a debug log that you can view in the "nuDebug Results" section of the application's menu.

Each entry in the debug log includes:

A timestamp
A description of the context (e.g., procedure name, event, or SQL error)

Examples of context labels:

Procedure – e.g., "Procedure ABC line 1"
Event – e.g., "Before Edit of Form nuhome line 5"
SQL Error – e.g., "SQL Error in nuRunQuery"

This function is particularly useful for:

Tracing execution flow
Inspecting variable contents
Debugging code

Example usage 1: Output a variable

Code: Select all

$a = 'Bob';
nuDebug($a);

Example usage 2: Set a categroy

Code: Select all

nuDebug::setFlag('Test')->log('Error: Failed to retrieve data..');

Example usage 3: Output multiple variables

Code: Select all

$s = 'Hello world';
$a = [1, 2, 3, 4];
$o = ['name' => 'Bob', 'phone' => '555 123456'];
nuDebug($s, $a, $o);

To view the output, open nuDebug Results from the Options menu or press CTRL+SHIFT+D after running your code.
