## ffi-pinyin

该项目是将中文汉字转换成拼音，使用`rust`构建动态链接库来给`php`调用。
该库主要是为了提高`php`中文转换拼音的性能问题而构建（__特别是长文章__）。

### 环境

需要`php >= 7.4` 以上的版本并且开启了`FFI`扩展。如果你需要自己编译库还需要装`rust` 工具链。

还需要设置`php.ini` 中的`ffi.enable`为`On`。

### Usage

该库提供四种基础用法：不带音标，带音标，首字母，多音字带音标。

```php
<?php

include __DIR__ . '/../src/Pinyin.php';

$py = FastFFI\Pinyin\Pinyin::new();

echo "无音标: ", $py->plain("中国人...😄😄👩", false, false), "\n";
echo "音标: ", $py->tone("中国人", false, false), "\n";
echo "音标数字: ", $py->toneNum("中国人", false, false), "\n";
echo "音标数字结尾: ", $py->toneNumEnd("中国人", false, false), "\n";
echo "首字母: ", $py->letter("中国人", false, false), "\n";
echo "音标转换模式: ", $py->tone("中国人😄😄", true, false), "\n";
echo "音标多音词模式: ", $py->tone("中国人", false, true), "\n";

echo "音标未识别跳过: ", $py->plain("PHP永远滴神，rust永远的神", true, false, '-'), "\n";
echo "音标未识别不分隔: ", $py->plain("PHP永远滴神，rust永远的神", false, false, '-', true), "\n";

var_export($py->plainArray("PHP永远滴神，rust永远的神", false, false, true));
```

以上程序执行后的结果:

```text
无音标: zhong guo ren . . . 😄 😄 👩
音标: zhōng guó rén
音标数字: zho1ng guo2 re2n
音标数字结尾: zhong1 guo2 ren2
首字母: z g r
音标转换模式: zhōng guó rén
音标多音词模式: zhōng:zhòng guó rén
音标未识别跳过: yong-yuan-di-shen-yong-yuan-de-shen
音标未识别不分隔: PHP-yong-yuan-di-shen-，rust-yong-yuan-de-shen

array (
  0 => 'PHP',
  1 => 'yong',
  2 => 'yuan',
  3 => 'di',
  4 => 'shen',
  5 => '，rust',
  6 => 'yong',
  7 => 'yuan',
  8 => 'de',
  9 => 'shen',
)
```

多音字是以`:`来连接的。

### Benchmark

选用了比较流行的`https://github.com/overtrue/pinyin` 作为比较对象。

使用的测试命令:

```shell
[meshell@ffi-pinyin#] ./vendor/bin/phpbench run --report=default 
```

使同等数据循环100次测试结果:

相比之下与比较对象最快的也相差45倍的性能之差。

相比之下与比较对象最快的差不多20倍的性能之差。

### FAQ

- 在`centos`上执行失败?
  
  确定是不是`glibc`版本过低。可以使用`ldd lib/libffi_pinyin.so` 来查看库信息。
如果出现`/lib64/libc.so.6: version 'glibc_2.18' not found`就说明你服务的`glibc`版本过低。 
  下载glibc编译升级，下载地址: `wget http://mirrors.ustc.edu.cn/gnu/libc/glibc-2.18.tar.gz`
