# SensitiveParameter 注解

(PHP 8 >= 8.2.0)

## 简介

该注解用于标记敏感参数，如果出现在栈跟踪中，则应编辑其值。

## 类摘要

#[\Attribute]
final class SensitiveParameter {
/* 方法 */
public __construct()
}

## 示例

`<?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;
}
?>`

上述示例在 PHP 8.2 中的输出类似于：

    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}
