# The SensitiveParameter class

(PHP 8 >= 8.2.0)

## Introducción

This attribute is used to mark a parameter that is sensitive and should have its value redacted if present in a stack trace.

## Sinopsis de la Clase

final class SensitiveParameter {
/* Métodos */
public __construct()
}

## Ejemplos

`<?php
function defaultBehavior(
string $secret,
string $normal
) {
throw new Exception('Error!');
}
function sensitiveParametersWithAttribute(
#[\SensitiveParameter]
string $secret,
string $normal
) {
throw new Exception('Error!');
}
try {
defaultBehavior('password', 'normal');
} catch (Exception $e) {
echo $e, PHP_EOL, PHP_EOL;
}
try {
sensitiveParametersWithAttribute('password', 'normal');
} catch (Exception $e) {
echo $e, PHP_EOL, PHP_EOL;
}
?>`

Output of the above example in PHP 8.2 is similar to:

    Exception: Error! in example.php:7
    Stack trace:
    #0 example.php(19): defaultBehavior('password', 'normal')
    #1 {main}

    Exception: Error! in example.php:15
    Stack trace:
    #0 example.php(25): sensitiveParametersWithAttribute(Object(SensitiveParameterValue), 'normal')
    #1 {main}
