Create sitemap.xml file dynamically on root folder with one hit

I had created one controller file which can create sitemap.xml file(which is used for seo, google crawler and many other puropse) dynamically with one run.

This article is use for Yii framework basic structure and This FrontEnd/BackEnd seperated directory structure

I had reference This Extension for development.

Create one controller file in controller folder named KsitemapController and copy paste below code in that controller file and Just run that controller with its default action ( index action )

You just need to change default variable as your requirements,

$protectedControllers => "Contain array of controllers which should not include in sitemap.xml file, means its methods also not included in sitemap.xml"

$protectedActions => "Contain array of actions which should not include in sitemap.xml"

$priority, $changefreq, $lastmod are other parameters which you can set as requirement.

<?php
class KsitemapController extends Controller
{
	public $protectedControllers = array('ksitemap');   //controller array will not added in sitemap.xml
	public $protectedActions =array('site/error','site/logout');      //controller/action array will not added in sitemap.xml
	public $priority = '0.5';                           //default priority for all url
	public $changefreq = 'daily';                       //default frequency for all url
	public $lastmod = '1985-10-07';				        //default last modified date
			
	public function actionIndex()
	{
		Yii::import('application.controllers.*');
		//Yii::import('application.controllers.back.*'); //if you are using front/back type of directory structure, just define controller folder back/front
		$urls = array();
		$directory = Yii::getPathOfAlias('application.controllers');
		//$directory = Yii::getPathOfAlias('application.controllers.back'); //if you are using front/back type of directory structure, just define controller folder back/front
		$iterator = new DirectoryIterator($directory);
		
		foreach ($iterator as $fileinfo)
		{
			if ($fileinfo->isFile() and $fileinfo->getExtension() == 'php')
			{
				$className = substr($fileinfo->getFilename(), 0, -4); //strip extension
				$class = new ReflectionClass($className);
						
				foreach ($class->getMethods(ReflectionMethod::IS_PUBLIC) as $method)
				{										
					$methodName = $method->getName();
					if (strpos($methodName, 'action') === 0) //only methods starts with action included
					{	
						$controller = lcfirst(substr($className, 0, strrpos($className, 'Controller')));
						$action = lcfirst(substr($methodName, 6));
						if (!$this->isProtected($controller, $action)) //refer isProtected function
							$this->addUrl($urls, "$controller/$action"); //refer addUrl function
					}
				}
			}
		}
		
		//below array $url converted into required(sitemap.xml) structure		
		$xmldata = '<?xml version="1.0" encoding="utf-8"?>'; 
		$xmldata .= '<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">';
		foreach ($urls as $url => $data)
		{
			$xmldata .= '<url>';
			$xmldata .= '<loc>'.$url.'</loc>';
			$xmldata .= '<lastmod>'.$data['lastmod'].'</lastmod>';
			$xmldata .= '<changefreq>'.$data['changefreq'].'</changefreq>';
			$xmldata .= '<priority>'.$data['priority'].'</priority>';
			$xmldata .= '</url>';
		}	
		$xmldata .= '</urlset>'; 
		
		if(file_put_contents('sitemap.xml',$xmldata))
		{
			echo "sitemap.xml file created on project root folder..";	
		}
	
	}
		
	protected function addUrl(&$urls, $action, $args = array()) //generate url and globaly default passed parameters as array
	{
		$url = Yii::app()->createAbsoluteUrl($action, $args);
				
		$prefs = array();		
		$defPrefs = array(
			'lastmod' => $this->lastmod ? $this->lastmod : date('Y-m-d'),
			'changefreq' => $this->changefreq ? $this->changefreq : 'daily',
			'priority' => $this->priority ? $this->priority : 0.5,
		);		
		$prefs = array_merge($defPrefs, $prefs);		
		$urls[$url] = $prefs;
	}
		
	protected function isProtected($controller, $action) //check protected controller/action present in publicly defined global array 
	{
		return in_array($controller, $this->protectedControllers) or 
			in_array("$controller/$action", $this->protectedActions);
	}
}

Tadaa... This is it. you can see sitemap.xml file created on project root folder.
