How can code readability be improved by breaking down PHP code into multiple lines?

Breaking down PHP code into multiple lines can improve code readability by making it easier to follow the logic and structure of the code. This can be achieved by breaking long lines of code into shorter, more manageable lines, and using indentation to clearly show the hierarchy of the code.

// Example of breaking down PHP code into multiple lines for improved readability

$longVariableName = 'This is a long string that needs to be broken down into multiple lines for better readability';

// Break down the long string into multiple lines
$longVariableName = 'This is a long string that needs to be broken down ' .
                    'into multiple lines for better readability';
