PHP 5.3: The Good, the Bad and the Ugly

June 30, 2009 by Glen. Filed under php.

PHP 5.3 was released today; here are my positive and negatives:

Anonymous functions created with create_function have always been a bit messy. With 5.3 comes support for closures with a much cleaner syntax:

    $greet = function($name)
    {
        printf("Hello %s\r\n", $name);
    };

    $greet('World');
    $greet('PHP');

Although not a massive change from 5.2, there are enough differences to break existing code.

There has been quite a discussion about PHP’s new namespace syntax.

$c = new \my\name\MyClass;

It’s just damn ugly. The more sensible choice, :: is already used as the scope resolution operator and was therefore dismissed.
