PHPAnalysis是目前广泛使用的中文分词类,使用反向匹配模式分词,因此兼容编码更广泛,现将其变量与常用函数详解如下:
一、比较重要的成员变量
$resultType = 1 生成的分词结果数据类型(1 为全部, 2为 词典词汇及单个中日韩简繁字符及英文, 3 为词典词汇及英文)
这个变量一般用 SetResultType( $rstype ) 这方法进行设置。
$notSplitLen = 5 切分句子最短长度
$toLower = false 把英文单词全部转小写
$differMax = false 使用最大切分模式对二元词进行消岐
$unitWord = true 尝试合并单字(即是新词识别)
$differFreq = false 使用热门词优先模式进行消岐
二、主要成员函数列表
1、public function __construct($source_charset='utf-8', $target_charset='utf-8', $load_all=true, $source='')
函数说明:构造函数
参数列表:
$source_charset 源字符串编码
$target_charset 目录字符串编码
$load_all 是否完全加载词典(此参数已经作废)
$source 源字符串
如果输入输出都是utf-8,实际上可以不必使用任何参数进行初始化,而是通过 SetSource 方法设置要操作的文本
2、public function SetSource( $source, $source_charset='utf-8', $target_charset='utf-8' )
函数说明:设置源字符串
参数列表:
$source 源字符串
$source_charset 源字符串编码
$target_charset 目录字符串编码
返回值:bool
3、public function StartAnalysis($optimize=true)
函数说明:开始执行分词操作
参数列表:
$optimize 分词后是否尝试优化结果
返回值:void
一个基本的分词过程:
//////////////////////////////////////
$pa = new PhpAnalysis();
$pa->SetSource('需要进行分词的字符串');
//设置分词属性
$pa->resultType = 2;
$pa->differMax = true;
$pa->StartAnalysis();
//获取你想要的结果
$pa->GetFinallyIndex();
////////////////////////////////////////
4、public function SetResultType( $rstype )
函数说明:设置返回结果的类型
实际是对成员变量$resultType的操作
参数 $rstype 值为:
1 为全部, 2为 词典词汇及单个中日韩简繁字符及英文, 3 为词典词汇及英文
返回值:void
5、public function GetFinallyKeywords( $num = 10 )
函数说明:获取出现频率最高的指定词条数(通常用于提取文档关键字)
参数列表:
$num = 10 返回词条个数
返回值:用","分隔的关键字列表
6、public function GetFinallyResult($spword=' ')
函数说明:获得最终分词结果
参数列表:
$spword 词条之间的分隔符
返回值:string
7、public function GetSimpleResult()
函数说明:获得粗分结果
返回值:array
8、public function GetSimpleResultAll()
函数说明:获得包含属性信息的粗分结果
属性(1中文词句、2 ANSI词汇(包括全角),3 ANSI标点符号(包括全角),4数字(包括全角),5 中文标点或无法识别字符)
返回值:array
9、public function GetFinallyIndex()
函数说明:获取hash索引数组
返回值:array('word'=>count,...) 按出现频率排序
10、public function MakeDict( $source_file, $target_file='' )
函数说明:把文本文件词库编译成词典
参数列表:
$source_file 源文本文件
$target_file 目标文件(如果不指定,则为当前词典)
返回值:void
11、public function ExportDict( $targetfile )
函数说明:导出当前词典全部词条为文本文件
参数列表:
$targetfile 目标文件
返回值:void

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
