Sitemap Generator

Class implementation

Features

• Actually crawls webpages like Google would
• Generates a seperate XML file which gets updated every time the script gets executed (Runnable via CRON)
• Awesome for SEO
• Crawls faster than online services
• Verbose logging
• Completely usable through CLI
• Color support in CLI mode
• Customizable
• Author is active on Github, open an issue for support
• Literally the best open-source sitemap script written in PHP
• Non-restrictive licensing

Usage

Usage is pretty strait forward:

• Configure the crawler by modifying the config section of the sitemap.php file
  • Select the file to which the sitemap will be saved
  • Select URL to crawl
  • Configure blacklists, accepts the use of wildcards (example: http://example.com/private/* and *.jpg)
• Generate sitemap
  • Either send a GET request to this script or use it from the CLI as seen below
  • A sitemap will be generated and saved
  • Submit to Google
• For better results
  • Setup a CRON Job to execute the php script

Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist knyzorg/sitemap-generator-crawler "dev-master"

or add

"knyzorg/sitemap-generator-crawler": "dev-master"

to the require section of your composer.json file.

Usage

For example, in your php-framework or your Class

use knyzorg\sitemap\SitemapCrawler;

class SitemapController extends Controller
{
    public function actionIndex()
    {
        $crawler = new SitemapCrawler();
        $crawler->site='http://mites/';
        $crawler->file= \Yii::getAlias("@frontend/web/sitemap.xml");
        $crawler->start();
    }
}

CLI Usage

Sometimes you need to run the script for a large number of domains (If you are a webhost for example). This sitemap generator allows you to override any variable on-the-fly in CLI.

Basic usage

Scan http://www.mywebsite.com/ and output the sitemap to /home/user/public_html/sitemap.xml:

php sitemap.php file=/home/user/public_html/sitemap.xml site=http://www.mywebsite.com/

Advanced usage

While the above is the most common use-case, sometimes you need to modify other things such as $debug or $blacklist. I will do a bit of explaining about how shells work so you don't mess up.

Lets start with the blacklist which is a one-dimensional array. This is how you would pass an array as a GET request.

php sitemap.php blacklist[]="foo"&blacklist[]="bar"

Shells are different however as [] is parsed as a shell expansion and & as a fork-to-background. You want neither of those things. As such, you want to escape both of them resulting in the following:

php sitemap.php blacklist\[]="foo"\&blacklist\[]="bar"

Next, let's tackle the $debug variable. All the same concepts apply but the syntax is slightly different:

php sitemap.php debug\["add"]=true\&debug\["warn"]=false\&debug\["reject"]=true

Important note: Overriding an array does exactly what it means. Previously defined elements are destroyed.
