How can line breaks be inserted effectively in PHP code to improve readability?

To improve readability in PHP code, line breaks can be inserted effectively by breaking long lines of code into shorter, more manageable segments. This can help make the code easier to read and understand, especially when dealing with complex logic or multiple function calls within a single line.

// Example of inserting line breaks in PHP code for improved readability
$longVariableName = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua';

// Breaking the long line into shorter segments
$shortVariableName = 'Lorem ipsum dolor sit amet, ' .
                     'consectetur adipiscing elit, ' .
                     'sed do eiusmod tempor incididunt ' .
                     'ut labore et dolore magna aliqua';

echo $shortVariableName;
