<?php

    $arr = [
        [
            'id'=>1,
             'name'=>'Tom'
        ],
        [
            'id'=>2,
             'name'=>'Tom'
        ],
        [
            'id'=>3,
             'name'=>'Tom'
        ],
        [
            'id'=>4,
             'name'=>'Tom'
        ],
        [
            'id'=>5,
             'name'=>'Tom'
        ]
    ];
    $arr1 = array_filter($arr,function($val){return $val['id'] < 3;});
    $arr2 = array_filter($arr,function($val){return $val['id'] > 3;});

    $arr3 = array_filter($arr,function($val){return $val['id'] ==4;});

var_dump($arr2);exit; ?>
