Sort

Introduction #

Sort process helps you to sort data based on columns. It works like the SORT BY in SQL Statement. The input array contains key=>value where key will be column name and the value is the direction of sort.

Examples #

Simple sorting #

<?php
use \koolreport\processes\Sort;
class MyReport extends \koolreport\KoolReport
{
    public function setup()
    {
        ...
        ->pipe(new Sort(array(
            "age"=>"asc",
            "name"=>"desc"
        ));
        ...
    }
}

Advanced sorting with function #

If you need sort differently rather than simple desc or asc, you can set your own comparison function.

<?php
use \koolreport\processes\Sort;
class MyReport extends \koolreport\KoolReport
{
    public function setup()
    {
        ...
        ->pipe(new Sort(array(
            "age"=>function($a,$b){
                return $a<$b;
            },
        ));
        ...
    }
}
