Examples can be found in the test package in the latest release.
A basic exampleLet's say we have an array of strings and want to select only the strings whose length is < 5. The PHPLinq way of achieving this would be the following:
// Create data source $names = array("John", "Peter", "Joe", "Patrick", "Donald", "Eric"); $result = from('$name')->in($names) ->where('$name => strlen($name) < 5') ->select('$name');
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) < 5 doing? This piece of code is compiled to an anonymous function or Lambda expression under the covers. This function accepts a parameter $name, and returns a boolean value based on the expression strlen($name) < 5. （待续...）
