How to Generate Dynamic XML Sitemap for Website in PHP

Muhammad Yaseen 0 Friday, September 08, 2023

I get emails daily asking me to provide links to their website, most of them are spammy websites. I really laugh them out. Those spammy backlink guys should learn and keep up with technology.Reason being, Google is far ahead in the game. How many backlinks you got is one outdated parameter. Google has got thousands of data points to validate and rank a website. Definitely it will sieve out the <a href="https://developers.google.com/search/docs/advanced/guidelines/link-schemes" style="color: #2f20d1; text-decoration-line: none;">spammy links</a> easily.If you want to help Google and rank you up, there is one good thing to do. Create a valid sitemap for your website and submit it to Google. It will help its bots to index the website and map it the way you wish, eventually ranking you high in search results. SEO win!<img alt="Sitemap" class="alignnone size-large wp-image-13307" height="424" loading="lazy" sizes="(max-width: 550px) 100vw, 550px" src="https://phppot.com/wp-content/uploads/2021/03/sitemap-550x424.jpg" srcset="https://phppot.com/wp-content/uploads/2021/03/sitemap-550x424.jpg 550w, https://phppot.com/wp-content/uploads/2021/03/sitemap-300x231.jpg 300w, https://phppot.com/wp-content/uploads/2021/03/sitemap-768x591.jpg 768w, https://phppot.com/wp-content/uploads/2021/03/sitemap.jpg 1000w" style="border-radius: 15px; border: 0px; height: auto; max-width: 100%; vertical-align: middle;" width="550" />A sitemap is a mapping file that has the specification about the site page URLs and more related details. It may also map other content URLs of the posts, products, images, videos, news and more in a conventional structure.There are conventions for the XML schema for the <a href="https://www.sitemaps.org/protocol.html" rel="noopener noreferrer" style="color: #2f20d1; text-decoration-line: none;" target="_blank">sitemap protocol</a>.It lets the search engine crawlers <a href="https://phppot.com/php/php-xml-parser/" style="color: #2f20d1; text-decoration-line: none;">parse the sitemap XML</a> and provide valuable details. These details are useful to optimize the web pages, content and the relationship between them.The search engine crawlers capture the recently updated pages among the others. It will help to gain reputations based on the change frequencies.Let’s discuss generating sitemaps for a website and its importance more in the upcoming sections.It has an example to create a dynamic XML sitemap in PHP with a database.<img alt="Generated Sitemap Xml" class="alignnone wp-image-13236 size-large" height="293" loading="lazy" sizes="(max-width: 550px) 100vw, 550px" src="https://phppot.com/wp-content/uploads/2021/03/generated-sitemap-xml-550x293.png" srcset="https://phppot.com/wp-content/uploads/2021/03/generated-sitemap-xml-550x293.png 550w, https://phppot.com/wp-content/uploads/2021/03/generated-sitemap-xml-300x160.png 300w, https://phppot.com/wp-content/uploads/2021/03/generated-sitemap-xml.png 656w" style="border-radius: 15px; border: 0px; height: auto; max-width: 100%; vertical-align: middle;" width="550" /><h2 style="color: #2f2f2f; font-family: -apple-system, BlinkMacSystemFont, Roboto, "Segoe UI", "Helvetica Neue", Helvetica, Arial, sans-serif; margin-top: 1.3em;">What is inside?</h2><ol style="color: #2f2f2f; font-family: -apple-system, BlinkMacSystemFont, Roboto, "Segoe UI", "Helvetica Neue", Helvetica, Arial, sans-serif;"><li style="line-height: 1.5; margin: 6px 0px;"><a href="https://phppot.com/php/how-to-generate-dynamic-xml-sitemap-for-website-in-php/#importance-of-sitemap" style="color: #2f20d1; text-decoration-line: none;">Importance of sitemap</a></li><li style="line-height: 1.5; margin: 6px 0px;"><a href="https://phppot.com/php/how-to-generate-dynamic-xml-sitemap-for-website-in-php/#tools-to-create-sitemaps" style="color: #2f20d1; text-decoration-line: none;">Tools to create sitemaps</a></li><li style="line-height: 1.5; margin: 6px 0px;"><a href="https://phppot.com/php/how-to-generate-dynamic-xml-sitemap-for-website-in-php/#about_this_example" style="color: #2f20d1; text-decoration-line: none;">About this example</a></li><li style="line-height: 1.5; margin: 6px 0px;"><a href="https://phppot.com/php/how-to-generate-dynamic-xml-sitemap-for-website-in-php/#database_script" style="color: #2f20d1; text-decoration-line: none;">Database script</a></li><li style="line-height: 1.5; margin: 6px 0px;"><a href="https://phppot.com/php/how-to-generate-dynamic-xml-sitemap-for-website-in-php/#generate_sitemap_dynamically_in_php" style="color: #2f20d1; text-decoration-line: none;">Generate sitemap dynamically in PHP</a></li><li style="line-height: 1.5; margin: 6px 0px;"><a href="https://phppot.com/php/how-to-generate-dynamic-xml-sitemap-for-website-in-php/#sitemap_service_in_php_to_construct_xml" style="color: #2f20d1; text-decoration-line: none;">Sitemap service in PHP to construct XML</a></li><li style="line-height: 1.5; margin: 6px 0px;"><a href="https://phppot.com/php/how-to-generate-dynamic-xml-sitemap-for-website-in-php/#output_sitemap_xml_data_format" style="color: #2f20d1; text-decoration-line: none;">Output sitemap XML data format</a></li></ol><h2 id="importance-of-sitemap" style="color: #2f2f2f; font-family: -apple-system, BlinkMacSystemFont, Roboto, "Segoe UI", "Helvetica Neue", Helvetica, Arial, sans-serif; margin-top: 1.3em;">Importance of sitemap</h2>The sitemap is one of the key tools to let the search engine crawl bots to get the site structure.

Also, the sitemap generators are launched as a SaaS product and provide various scales of features for their subscribers.The XML-Sitemaps Generator is a popular online tool to create sitemaps.

It has been discussed with a suitable example to make everything clear about this process.We have discussed the importance of the sitemap for a website. Also, we see some example tools available online to generate and manage sitemaps.This example has created the sitemap index for the number of sitemaps generated. I hope, this is helpful to get an idea about creating a custom sitemap generated by our own.<a class="download" href="https://phppot.com/downloads/generate-sitemap-in-php.zip" style="border-radius: 50px; border: 1px solid rgb(213, 217, 217); color: #2f2f2f; display: inline-block; margin: 20px 40px 20px 0px; padding: 8px 12px 8px 18px; position: relative; text-align: center; text-decoration-line: none; text-transform: lowercase; width: 130px;">download</a>
