How to Achieve PHP's preg_replace_callback() Functionality in Java?

A Java Alternative to PHP's preg_replace_callback

When transitioning code from PHP to Java, a common challenge arises in finding an equivalent for PHP's preg_replace_callback() function. This function enables the use of a callback function for each match in a regular expression, passing the match text as an argument.

PHP Example

Consider the following PHP code:

Java Equivalent

In Java, a comparable approach can be achieved using the appendReplacement() and appendTail() methods within a loop:

This code provides the flexibility to customize the replacement text dynamically for each match, mimicking the callback functionality in PHP.

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

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.
