What techniques can PHP developers use to properly debug and resolve parse errors, unexpected end errors, and other syntax-related issues in their code, especially when working with includes and file paths?

When encountering parse errors, unexpected end errors, or other syntax-related issues in PHP code, developers can use techniques such as checking for missing or mismatched parentheses, brackets, or quotes, ensuring proper syntax for control structures like if statements or loops, and verifying the correct usage of PHP functions and language constructs. When working with includes and file paths, it's important to double-check the paths and file names for accuracy, use the correct directory separators (forward slashes on Unix-based systems, backslashes on Windows), and consider using absolute paths or the `__DIR__` constant to ensure the correct file is included.

// Example of using absolute paths and the __DIR__ constant to include a file
include __DIR__ . '/path/to/file.php';
