只是举例,就是类似这样的标签快速替换
$html = "

abc,abc,abc,abc,......
"
将html中所有的  "abc" 字符
替换成
"1"
"2"
"3"
...

即:$html = "
1,2,3,4,......
"

这替换标签里面的内容,用的是javascript(jQuery)吧。

额,替换后 我还要存到数据库的。所以是在后台PHP替换的啊。

$html = "<div>abc,abc,abc,<span>abc</span>,......</div>";echo preg_replace('/abc/e','++$i',$html);
Copy after login
Copy after login

$str = '<div>abc,abc,abc</div><span>abc</span>';$i=1;$newstr = preg_replace_callback('|abc|', function($match) use(&$i){return $i++;}, $str);echo $newstr;
Copy after login

两位都很牛啊, preg_replace_callback好象可以连接字符串return 'str'.$i++;


preg_replace可以连接不?
'str ++$i str'会报错

$html = "<div>abc,abc,abc,<span>abc</span>,......</div>";echo preg_replace('/abc/e','++$i',$html);
Copy after login
Copy after login

echo preg_replace('/abc/e','"str".++$i',$html);
Copy after login



我一直也怀疑是这2个函数,但一直没找到你们这样的用法。。。。
分给你们啦!

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

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.

What are Enumerations (Enums) in PHP 8.1? What are Enumerations (Enums) in PHP 8.1? Apr 03, 2025 am 12:05 AM

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

Explain late static binding in PHP (static::). Explain late static binding in PHP (static::). Apr 03, 2025 am 12:04 AM

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
