What best practice advice can be given for parsing values using PHP functions like strrchr?

When parsing values using PHP functions like strrchr, it's important to handle edge cases where the function may not find the desired substring. To address this, it's recommended to check if the function returns false before attempting to use the result. This can help prevent errors and ensure the code behaves as expected.

// Example code snippet demonstrating best practice advice for parsing values using strrchr
$string = "Hello, World!";
$delimiter = ",";
$result = strrchr($string, $delimiter);

if ($result !== false) {
    $parsedValue = substr($result, 1); // Remove the delimiter from the result
    echo $parsedValue;
} else {
    echo "Delimiter not found in the string.";
}
