php正则匹配汉字结尾的字符串
UTF-8格式
$str = "289dfh第一个匹配 jdfh388第二个匹配 jfsj83第三个匹配 sjfsui"
要匹配出 1)289dfh第一个匹配
2)jdfh388第二个匹配
3)jfsj83第三个匹配
回复讨论(解决方案)
$str = "289dfh第一个匹配 jdfh388第二个匹配 jfsj83第三个匹配 sjfsui";preg_match_all('/\w+[\x{4e00}-\x{9fa5}]/iu', $str, $r);print_r($r[0]);
(
[0] => 289dfh第一个匹配
[1] => jdfh388第二个匹配
[2] => jfsj83第三个匹配
)
我想用环视做,左边不以汉字开头做界,右边以汉字结尾做界,这样怎么写呢?
<?php$str = "289dfh第一个匹配 jdfh388第二个匹配 jfsj83第三个匹配 sjfsui 汉字开头的不要 haha这个要";preg_match_all('/\s*(?![\x{4e00}-\x{9fa5}])\w+[\x{4e00}-\x{9fa5}]+/iu', $str, $r);print_r($r[0]);
你指的是这个不?
否定顺序环就可以啦 ~~~

你这个是黑名单做法,范围太大了,应该改用白名单,规定开头是什么才对
<?php$str = "289dfh第一个匹配 jdfh388第二个匹配 jfsj83第三个匹配 sjfsui 汉字开头的不要 haha这个要";preg_match_all('/\s*(?![\x{4e00}-\x{9fa5}])\w+[\x{4e00}-\x{9fa5}]+/iu', $str, $r);print_r($r[0]);

为什么把结尾的/iu去掉,会报错
Compilation failed: character value in \x{...} sequence is too large at offset 8
/iu
i表示忽略大小写
u表示utf8
/iu
i表示忽略大小写
u表示utf8
把U去掉,显示错误,为什么不指定U,就错误啊

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.
