How does the include() function interact with conditional statements like if-else in PHP?

When using the include() function within conditional statements like if-else in PHP, it's important to remember that the include() function simply inserts the specified file at that point in the code. Therefore, the file will be included regardless of whether the condition in the if statement is true or false. To address this issue, you can use the require() function instead of include() within the conditional statement, as require() will cause a fatal error if the specified file cannot be included. 

<?php
if ($condition) {
    require 'file.php';
} else {
    // do something else
}
?>
