php 中有汉字转拼音,那如果用拼音去找汉字怎么弄?
那如果用拼音去找汉字怎么弄?
如果调用一个txt中文本,将每一行内容转为拼音,
这个简单,而且效率很高,那么用拼音再去找汉字,突然发现效率出奇的低,
头疼中!!!!!
define( "DIR", dirname( __FILE__ ) );
$Titleline=file(DIR."/hanzi.txt");
$TC=count($Titleline);
$pinyin="woaini";
for ($i = 1; $i $x=strcmp ($yuming,py($Titleline[$i]));
if($x == 0):
$Title1=$Titleline[$i];
break;
endif;
}
代码是上面的样子
py 是汉字转拼音函数
问题出现了,当hanzi.txt 大小超过1-3M,,,速度会非常的慢,,,
怎么处理这个问题,,,
回复讨论(解决方案)
先说明一下,由于同音字的存在(同音不同义的很多)
所以从 拼音去找汉字 基本是无意义的
用多重哈希表组织数据可以高效的查询

用多重哈希表组织数据可以高效的查询 这个能给个例子吗?

用多重哈希表组织数据可以高效的查询 对了,我不能使用数据库。。只能操作txt
使用 trie 算法就可以了
按照《汉语拼音方案》所有的汉字只有声母和韵母构成,如果能加上声调就更好了
至多也就是三重哈希表就完成了

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.
