What potential pitfalls should be considered when implementing automatic line breaks in PHP code?

When implementing automatic line breaks in PHP code, it is important to consider potential pitfalls such as breaking code functionality by inserting line breaks in inappropriate places, affecting the readability of the code for other developers, and potentially causing unintended errors due to misplaced line breaks. To avoid these pitfalls, it is recommended to use automatic line breaks sparingly and only in cases where it significantly improves code readability. Additionally, it is important to test the code thoroughly after implementing automatic line breaks to ensure that it still functions correctly.

// Example of implementing automatic line breaks in PHP code
$longString = "This is a long string that needs to be broken into multiple lines for readability.";

// Using automatic line breaks sparingly
echo wordwrap($longString, 20, "<br>");
