PHP基础-如何读取xml内容变成table

1.xml

<?xml version="1.0" encoding='utf-8' ?>
<root>
    <items>
        <name>虾米大王</name>
        <age>22</age>
        <job>计算机</job>
    </items>
    <items>
        <name>虾米小王</name>
        <age>21</age>
        <job>网络管理</job>
    </items>

</root>

2.php

<?php
/**
 * Created by PhpStorm.
 */

class xml
{
    var $m_char = "utf-8";

    function __construct($ch = "utf-8")
    {
        $this->m_char = $ch;
    }

    function parse($xmlFile)
    {
        if(function_exists('simplexml_load_file'))
        {
            $xml = simplexml_load_file($xmlFile);
        }
        elseif(function_exists('file_get_contents'))
        {
            $xml = file_get_contents($xmlFile);
            $xml = new SimpleXMLElement($xml);
        }
        elseif(function_exists('fopen'))
        {
            $handle = fopen($xmlFile,'r');
            $xml = "";

            }
            fclose($handle);
            $xml = new SimpleXMLElement($xml);
        }
        else
        {
            $xml = false;
        }
        return $xml;
