PHP 8: the null safe operator

This technical article provides an in-depth look at the null safe operator introduced in PHP 8. It explains the operator's syntax (?->) for safely chaining method and property calls on potentially null objects, contrasts it with the null coalescing operator (??), and details edge cases, capabilities (like short-circuiting), and limitations. It includes code examples to illustrate proper usage and prevent common errors.
