# PHP的hash()函数中不同algo算法的性能对比
|
||||
|
||||
> wandoubaba / 2022-08-02
|
||||
|
||||
## hash()函数用法
|
||||
|
||||
`php.net`上的介绍：
|
||||
|
||||
```txt
|
||||
(PHP 5 >= 5.1.2, PHP 7, PHP 8, PECL hash >= 1.1)
|
||||
hash — 生成散列值（消息摘要）
|
||||
```
|
||||
|
||||
### 说明
|
||||
|
||||
```php
|
||||
hash(
|
||||
string $algo,
|
||||
string $data,
|
||||
bool $binary = false,
|
||||
array $options = []
|
||||
): string
|
||||
```
|
||||
|
||||
### 参数
|
||||
|
||||
|参数|说明|
|
||||
|---|---|
|
||||
|algo|要使用的散列算法的名称（例如：“sha256”）。 可以在 hash_algos() 中查看当前支持的算法。|
|
||||
|data|要进行散列运算的消息。|
|
||||
|binary|设置为 true 输出原始二进制数据， 设置为 false 输出小写 16 进制字符串。|
|
||||
|options|各种散列算法的一系列选项数组。 目前 MurmurHash 算法仅支持 “seed” 参数。|
|
||||
|
||||
### 返回值
|
||||
|
||||
如果 `binary` 设置为 `true，` 则返回原始二进制数据表示的信息摘要， 否则返回 16 进制小写字符串格式表示的信息摘要。
|
||||
|
||||
### 示例
|
||||
|
||||
```php
|
||||
<?php
|
||||
echo hash('sha256', 'The quick brown fox jumped over the lazy dog.');
|
||||
?>
|
||||
```
|
||||
|
||||
结果
|
||||
|
||||
```txt
|
||||
68b1282b91de2c054c36629cb8dd447f12f096d3e3c587978dc2248444633483
|
||||
```
|
||||
|
||||
## 性能测试代码
|
||||
|
||||
```php
|
||||
function hashTest()
|
||||
{
|
||||
$algos = hash_algos();
|
||||
$plaintext = (string)time();
|
||||
$result = [];
|
||||
foreach ($algos as $algo) {
|
||||
// 这是一个取当前微秒时间戳的方法，返回float
|
||||
$start = microtimeFloat();
|
||||
for ($i = 0; $i < 500000; $i++) {
|
||||
$hash = hash($algo, $plaintext);
|
||||
}
|
||||
$end = microtimeFloat();
|
||||
$duration = $end - $start;
|
||||
$result[] = [
|
||||
'algo' => $algo,
|
||||
'plaintext' => $plaintext,
|
||||
'hash' => $hash,
|
||||
'hash_length' => mb_strlen($hash),
|
||||
'duration' => $duration,
|
||||
];
|
||||
}
|
||||
usort($result, function ($a, $b) {
|
||||
if ($a['duration'] == $b['duration']) return 0;
|
||||
return ($a['duration'] < $b['duration']) ? -1 : 1;
|
||||
});
|
||||
return $result;
|
||||
}
|
||||
|
||||
/**
|
||||
* 取当前系统的微秒时间戳浮点值
|
||||
*
|
||||
* @author Aaron <chenqiang@h024.cn>
|
||||
*/
|
||||
function microtimeFloat()
|
||||
{
|
||||
list($usec, $sec) = explode(" ", microtime());
|
||||
return ((float)$usec + (float)$sec);
|
||||
}
|
||||
|
||||
$result = hashTest();
|
||||
// 保存结果
|
||||
file_put_contents('hashtest.log', json_encode($result, JSON_PRETTY_PRINT));
|
||||
// 打印写入结果到控制台
|
||||
echo json_encode($result, JSON_PRETTY_PRINT);
|
||||
```
|
||||
|
||||
第3行hash_algo()函数返回由当前系统所有已注册的哈希算法组成的数组，不同的环境下hash_algo()函数的返回值可能不相同；
|
||||
|
||||
第9行可以调整循环次数来调整程序执行时间；
|
||||
|
||||
第10行就是具体hash()函数的用法。
|
||||
|
||||
## 执行结果
