How can an IDE like NetBeans or Eclipse with PDT help in identifying duplicate class declarations in PHP?

An IDE like NetBeans or Eclipse with PDT can help in identifying duplicate class declarations in PHP by providing real-time syntax checking and highlighting errors in the code. This can save time and prevent potential bugs in the application.

```php
// Example PHP code snippet to demonstrate how an IDE can help identify duplicate class declarations

class MyClass {
    // Class code here
}

class MyClass {
    // Another class code here
}
```

In this example, the IDE will highlight the second class declaration as an error, indicating that there is a duplicate class declaration. This allows the developer to easily identify and fix the issue before running the code.
