What are some of the new functions and features in PHP5 that developers should be aware of?

One of the new features in PHP5 is the introduction of the "mysqli" extension, which provides improved support for MySQL databases and allows for object-oriented programming. Developers should also be aware of the addition of the "SimpleXML" extension, which simplifies the parsing and manipulation of XML data. Additionally, PHP5 includes a new error handling system that allows for better control and reporting of errors. 

// Example of using the mysqli extension to connect to a MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database_name");

if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

// Example of using SimpleXML to parse an XML file
$xml = simplexml_load_file("data.xml");

// Example of using the new error handling system
try {
    // code that may throw an error
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
}
