a implementation of linq to array

alinq

a branche of the libarary Plinq(http://plinq.codeplex.com/license) which is a implementation of linq to array.
基于Plinq(http://plinq.codeplex.com/license) 修改的一个以linq方式操作数组的php类., _(*1)

The Purpose of Branche

This branche of the libaray trying to implemente the same feature without using SPL RecursiveArrayIterator;br/ 这个分支试图在不依赖SPL RecursiveArrayIterator 这个标准库的情况下,实现与原Plinq同样的功能, _(*2)

Differences

• This branche add a new method Instance to Instance the Alinq class without using "new" keyword. Sometimes it's usefull,like the libaray live on a framework.br/ Here giving a example: 这个分支添加了一个新的方法：Instance,以传入的数组来实例化Alinq类，而不必使用new 关键字.br/ 这在某些情况下还是有点用的,比如在框架代码中调用这个类的时候。br/ 下面给出例子:

include('Alinq.php');

$alinq = new Alinq($array);
$otherAlinq = $alinq->Instance($newArray);

• Another difference is that some result of the this library are objects which could not used as array . The result object should call it's ToArray method to get array result.br/ 另外一个不同之处在与类库返回的结果,这个分支返回的对象结果不能直接作为数组使用,对象结果可以通过调用自身的ToArray方法来的到数组结果。 example:

include('Alinq.php');

$alinq = new Alinq($array);
$result = $alinq->Select(function($k, $v){ return $v['int']; })->ToArray();

Alinq methods that will return object:

• Instance()
• Single()
• GroupBy()
• Concat()
• SelectMany()
• Select()
• Where()
• Skip()
• Take()
• All()
• Any()
• Average()
• OrderBy()
• OrderByDescending()
• Max()
• Min()
• count()
• Distinct()
• Intersect()
• Diff()
• ElementAt()
• First()
• Last()
• Array2DInverse()
• ToArray()

Requirements

• PHP 5.3 or higher -- because of it depends on the new feature closures in PHP 5.3

Usage

include('Alinq.php');
$p = new Plinq($testArray);
$result = $p->Where(function($k, $v){ return ($v['int'] > 998); })->ToArray();
