This while loop will run n number of times or if we don't use or fetch the post using while loop then will the loop go infinite times?

Make sure to use the_post(); to fetch the post and this is important to finish the loop. Else the while loop will go infinite. Example of correct loop : <?php while ( have_posts () ){ the_post (); echo " hello " ; } ? > The above loop will print hello = no. of posts. Example of incorrect loop : <?php while ( have_posts () ){ echo " hello " ; } ? > The above loop will print hello infinite no. of times. the_title(); The php function fetches the title of the blogpos
