WordPress gets page ID method based on page name

When making a corporate theme, we usually need to show the company profile on the homepage, and the company profile is a single page. To get the content of this page is not difficult, the code is as follows:

<?php
$recent = new Wp_query (' page_id=1 ');
while ($recent->have_posts ()): $recent->the_post ();?>
<?php the_content ();?>
<?php Endwhile;?>

This will output the contents of the page with ID 1. However, when the user uses the topic, his company profile page ID is not necessarily 1, so you need to modify the page ID in the source code. Some humanized point of theme provides the theme of background management functions, then the user in the background input corresponding ID number is OK. But for beginners, you may not know how to get the page ID you want.
