首先用的是
米扑科技的开源项目：sitemap-PHP 自动生成网站地图
使用方式可以去github上看文档 https://github.com/mimvp/mimvp-sitemap-php
function testSitemap() { $sitemap = new \app\extra\Mysitemap("http://mimvp.com"); $sitemap->addItem('/','1.0','daily','Today'); $sitemap->addItem('/hr.PHP','0.8','monthly',time()); $sitemap->addItem('/index.PHP','Jun 25'$sitemap->addItem('/about.PHP','2017-06-26'); $sitemap->addItem('/hr2.PHP',1)">time())->addItem('/index2.PHP','Today')->addItem('/about2.PHP',1)">$sitemap->endSitemap(); }
核心代码：
首先在extra目录下引入类文件
Mysitemap.PHP
<?PHP namespace app\extra; use XMLWriter; /** * Sitemap * * 生成 Google Sitemap files (sitemap.xml) * * @package Sitemap * @author Sandy <sandy@mimvp.com> * @copyright 2009-2017 mimvp.com * @license http://opensource.org/licenses/MIT MIT License * @link http://github.com/mimvp/sitemap-PHP */ class Mysitemap { private $writer; // XMLWriter对象 $domain = "http://mimvp.com"; 网站地图根域名 $xmlFile = "sitemap"; 网站地图xml文件（不含后缀.xml） $xmlFileFolder = ""; 网站地图xml文件夹 $currXmlFileFullPath = ""; 网站地图xml文件当前全路径 $isSchemaMore= true; 网站地图是否添加额外的schema $current_item = 0; 网站地图item个数（序号） $current_sitemap = 0; 网站地图的个数（序号） const SCHEMA_XMLNS = 'http://www.sitemaps.org/schemas/sitemap/0.9'; const SCHEMA_XMLNS_XSI = 'http://www.w3.org/2001/XMLSchema-instance'const SCHEMA_XSI_SCHEMALOCATION = 'http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd'const DEFAULT_PRIORITY = 0.5const SITEMAP_ITEMS = 50000const SITEMAP_SEPERATOR = '-'const INDEX_SUFFIX = 'index'const SITEMAP_EXT = '.xml'; * * @param string $domain ： 初始化网站地图根域名 */ public function __construct($domain) { $this->setDomain(); } * * 设置网站地图根域名，开头用 http:// or https://,结尾不要反斜杠/ * @param string $domain ： 网站地图根域名 <br>例如: http://mimvp.com function setDomain() { if(substr($domain,-1) == "/") { $domain = strlen($domain)-1); } $this->domain = ; return $this; } * * 返回网站根域名 private getDomain() { $this->domain; } * * 设置网站地图的xml文件名 function setXmlFile($xmlFile$base = basename(); $dir = dirname(); if(!is_dir($dir)) { $res = mkdir(iconv("UTF-8","GBK",$dir),0777,1)">true); if($res) { echo "mkdir $dir success"; } else { echo "mkdir $dir fail."; } } $this->xmlFile = * * 返回网站地图的xml文件名 getXmlFile() { xmlFile; } function setIsChemaMore($isSchemaMore$this->isSchemaMore = getIsSchemaMore() { isSchemaMore; } * * 设置XMLWriter对象 function setWriter(XMLWriter $writer$this->writer = * * 返回XMLWriter对象 getWriter() { writer; } * * 返回网站地图的当前item * @return int getCurrentItem() { current_item; } * * 设置网站地图的item个数加1 incCurrentItem() { $this->current_item = $this->current_item + 1* * 返回当前网站地图（默认50000个item则新建一个网站地图） * @return int getCurrentSitemap() { current_sitemap; } * * 设置网站地图个数加1 incCurrentSitemap() { $this->current_sitemap = $this->current_sitemap + 1 getXMLFileFullPath() { $xmlfileFullPath = ""if (getCurrentSitemap()) { $xmlfileFullPath = $this->getXmlFile() . self::SITEMAP_SEPERATOR . $this->getCurrentSitemap() . self::SITEMAP_EXT; 第n个网站地图xml文件名 + -n + 后缀.xml } { $this->getXmlFile() . self::SITEMAP_EXT; 第一个网站地图xml文件名 + 后缀.xml } $this->setCurrXmlFileFullPath($xmlfileFullPath); 保存当前xml文件全路径 $xmlfileFullPath getCurrXmlFileFullPath() { currXmlFileFullPath; } function setCurrXmlFileFullPath($currXmlFileFullPath$this->currXmlFileFullPath = * * Prepares sitemap XML document startSitemap() { $this->setWriter(new XMLWriter()); $this->getWriter()->openURI($this->getXMLFileFullPath()); 获取xml文件全路径 $this->getWriter()->startDocument('1.0','UTF-8'$this->getWriter()->setIndentString("\t"$this->getWriter()->setIndent($this->getWriter()->startElement('urlset'getIsSchemaMore()) { $this->getWriter()->writeAttribute('xmlns:xsi',self::SCHEMA_XMLNS_XSI); $this->getWriter()->writeAttribute('xsi:schemaLocation',1)">SCHEMA_XSI_SCHEMALOCATION); } $this->getWriter()->writeAttribute('xmlns',1)">SCHEMA_XMLNS); } * * 写入item元素，url、loc、priority字段必选，changefreq、lastmod可选 function addItem($loc,1)">$priority = self::DEFAULT_PRIORITY,1)">$changefreq = NULL,1)">$lastmod = NULLif (($this->getCurrentItem() % self::SITEMAP_ITEMS) == 0) { getWriter() instanceof XMLWriter) { endSitemap(); } startSitemap(); incCurrentSitemap(); } incCurrentItem(); $this->getWriter()->startElement('url'$this->getWriter()->writeElement('loc',1)">$this->getDomain() . $loc); 必选 $this->getWriter()->writeElement('priority',1)">$priority); 必选 $changefreq$this->getWriter()->writeElement('changefreq',1)">$changefreq); 可选 } $lastmod$this->getWriter()->writeElement('lastmod',1)">$this->getLastModifiedDate($lastmod)); $this->getWriter()->endElement(); * * 转义时间格式，返回时间格式为 2016-09-12 function getLastModifiedDate($date=nullnull == $date$date = (); } if (ctype_digit()) { return date('c',1)">$date); Y-m-d } strtotime(); } } * * 结束网站xml文档，配合开始xml文档使用 endSitemap() { if (!getWriter()) { startSitemap(); } endElement(); endDocument(); flush(); } * * Writes Google sitemap index for generated sitemap files * * @param string $loc Accessible URL path of sitemaps * @param string|int $lastmod The date of last modification of sitemap.

($index ? self::SITEMAP_SEPERATOR . $index : '') . self::SITEMAP_EXT); $indexwriter->writeElement('lastmod',1)">)); $indexwriter->endElement(); } endDocument(); } }
然后控制器里使用
endSitemap();
}
我操作的时候遇到个坑，就是thinkPHP报错：XMLWriter 没找到
一开始我以为是没有装XMLWriter扩展，PHPinfo发现是有的，后来就在类文件Mysitemap.PHP，头部加上
namespace app\extra; use XMLWriter;
就可以了、
