What is the best practice for comparing strings in PHP to avoid errors related to newline characters?

When comparing strings in PHP, it's important to be mindful of newline characters that might be present at the end of the strings. These newline characters can cause discrepancies when comparing strings, leading to errors. To avoid this issue, it's recommended to trim both strings before comparing them using functions like `trim()` or `rtrim()`. 

$string1 = "Hello\n";
$string2 = "Hello";

if (trim($string1) === trim($string2)) {
    echo "Strings are equal";
} else {
    echo "Strings are not equal";
}
