What is the significance of using code tags and proper indentation in PHP programming?

Using code tags and proper indentation in PHP programming is significant because it helps improve the readability and maintainability of the code. Code tags make it easier to distinguish between code and text, while proper indentation organizes the code structure and makes it easier to understand the logic flow. This practice also makes debugging and troubleshooting more efficient.

<?php

// Example of using code tags and proper indentation
function greet($name) {
    echo "Hello, " . $name;
}

$name = "John";
greet($name);

?>
