What is a Loop in WordPress?

Loop in wordpress is a function used to display posts around the website. The loop function takes data like post title, post image, tags, meta to show list of posts. When we change the page number the loop just serves next set of records. Let say 500 posts and each page 10 posts, so there will be 50 pages, which is just a single page changing by loop of next set of data.

We can also use this to embed custom information blocks while building a new plugin theme. A loop can be used for a post, image gallery, carousel and more.

A loop in WordPress is a programming construct used to display a series of posts or other content on a WordPress site. The loop retrieves data from the WordPress database and outputs it in the desired format, such as a list of blog posts, a slider of featured images, or a gallery of product images. Loops are a fundamental part of WordPress themes and are used to display content on the home page, archive pages, category pages, and other areas of the site. Loops are constructed using PHP and can be customized to display content in different ways and to include different types of data, such as post titles, author information, and date of publication. The loop runs until all of the content that meets the specified criteria has been displayed.
