Feels familiar to SQL? Yes indeed! No more writing a loop over this array, checking the string''s length, and adding it to a temporary variable.

You may have noticed something strange... What''s that $name => strlen($name)

An advanced example

There are lots of other examples available in the PHPLinq download, but here''s an advanced one... Let''s say we have an array of Employee objects. This array should be sorted by Employee name, then Employee age. We want only Employees whose name has a length of 4 characters. Next thing: we do not want an Employee instance in our result. Instead, the returning array should contain objects containing an e-mail address and a domain name.

First of all, let''s define our data source:

class Employee {<br>    public $Name;<br>    public $Email;<br>    public $Age;<br><br>    public function __construct($name, $email, $age) {<br>        $this->Name     = $name;<br>        $this->Email     = $email;<br>        $this->Age        = $age;<br>
