How can the PHP code be optimized to reduce the number of lines and improve readability?

To optimize the PHP code and improve readability, you can use ternary operators, remove unnecessary variables, and refactor repetitive code blocks. This will help reduce the number of lines and make the code more concise and easier to understand.

// Original code
if ($condition) {
    $result = 'Condition is true';
} else {
    $result = 'Condition is false';
}

// Optimized code
$result = $condition ? 'Condition is true' : 'Condition is false';
