In what scenarios would it be more appropriate to use strcmp() for string comparison in PHP?

When comparing strings in PHP, it is more appropriate to use strcmp() when you need a binary-safe string comparison that considers the case sensitivity of the strings. This function returns 0 if the two strings are equal, a positive value if the first string is greater than the second, and a negative value if the first string is less than the second. It is useful when you need to compare strings in a case-sensitive manner or when you want to know the exact difference between two strings.

$string1 = "Hello";
$string2 = "hello";

$result = strcmp($string1, $string2);

if ($result == 0) {
    echo "The strings are equal.";
} elseif ($result < 0) {
    echo "String 1 is less than String 2.";
} else {
    echo "String 1 is greater than String 2.";
}
