How can beginners in PHP programming improve their understanding of nested parentheses and curly braces in code blocks?

Beginners in PHP programming can improve their understanding of nested parentheses and curly braces in code blocks by practicing writing and reading code with nested structures. They can also use code editors with syntax highlighting to visually differentiate between different levels of nesting. Additionally, referring to PHP documentation and tutorials on control structures can help clarify the proper usage of parentheses and curly braces in nested code blocks.
