How can backticks be used to handle reserved words in PHP code?

When dealing with reserved words in PHP code, backticks can be used to escape the reserved word and allow it to be used as a variable or identifier. By enclosing the reserved word in backticks, PHP will interpret it as a literal string rather than a reserved keyword. This can be useful when working with databases or APIs that have column names or endpoints that match PHP reserved words.
