php生成站点地图SiteMap文件

1. 安装

可以使用下面的composer包，也可以直接使用文末的类

composer require samdark/sitemap

2. 简单使用

use samdark\sitemap\Sitemap;
use samdark\sitemap\Index;
$sitemap = new Sitemap('./map/sitemap.xml');
// 链接地址、更新时间、更新周期、权重
$sitemap->addItem('https://www.codehui.net', time(), Sitemap::DAILY, 0.8);
$sitemap->addItem('https://www.codehui.net/info', time(), Sitemap::DAILY, 0.5);
// 写入文件
$sitemap->write();

3. 项目中使用

在项目里面一般需要的是批量生成，比如商品详情就需要包含动态参数、首页、关于我们这种不需要参数、有些平台呢单文件上限是10000个链接，下面分享个我在实战内使用的方法demo。

<?php
use samdark\sitemap\Sitemap;
use samdark\sitemap\Index;

使用方法

$sitemap = new SiteMapServices('https://www.codehui.net);
### 生成一个sitemap文件
$sitemap->generate()->createXml();
### 只生成商品相关页面的sitemap
$sitemap->getProductDetail()->createXml(__DIR__ . '/product_sitemap.xml');
### 生成sitemap文件，每1000个链接为一个文件
$sitemap->generate()->createChunkXml(__DIR__ . '/map/', 1000);
### 设置链接
$sitemap->setUrls([]);
### 获取链接
$sitemap->getProductDetail()->getUrls();
### 生成链接并提交到Baidu站长
$sitemap->generate()->submitBaidu();
### 生成链接并提交到Bing站长
$sitemap->generate()->submitBing();
