How can the use of echo vs. print affect the readability and efficiency of PHP code?

Using echo or print in PHP can affect the readability and efficiency of the code in different ways. In terms of readability, echo is often preferred as it is a language construct and does not require parentheses, making the code cleaner and easier to read. In terms of efficiency, echo is generally faster than print because it does not return a value. Therefore, using echo can lead to slightly better performance in PHP scripts.
