How can code tags in PHP forums help improve code readability and prevent errors like undefined variables?

Using code tags in PHP forums can help improve code readability by clearly distinguishing code snippets from surrounding text. This can prevent errors like undefined variables by making it easier for other users to identify and point out any mistakes in the code. Additionally, code tags can also preserve the formatting of the code, making it easier to follow the structure and logic. 

<?php
// Example code snippet with defined variables
$variable1 = "Hello";
$variable2 = "World";

echo $variable1 . " " . $variable2;
?>
