<?php

$res = $_POST['aoData'];
$sEcho = 0;
$iDisplayStart = 0; // 起始索引
$iDisplayLength = 0;//分页长度
$jsonarray= json_decode($res) ;
foreach($jsonarray as $value){
if($value->name=="sEcho"){
$sEcho=$value->value;
}
if($value->name=="iDisplayStart"){
$iDisplayStart=$value->value;
}
if($value->name=="iDisplayLength"){
$iDisplayLength=$value->value;
}
}
$Array = Array();
//此处生成50条数据，模仿数据库数据
for ($i = 1; $i < 51; $i++) {
$d = array($i,$i,$i,$i,$i);
Array_push($Array, $d);
}
$json_data = array ('sEcho'=>$sEcho,'iTotalRecords'=>50,'iTotalDisplayRecords'=>50,'aaData'=>array_slice($Array,$iDisplayStart,$iDisplayLength)); //按照datatable的当前页和每页长度返回json数据
$obj=json_encode($json_data);
echo $obj;
?>效果图：
