What is the purpose of using file() function in PHP to read HTML content and display it in an input field?

The purpose of using the file() function in PHP to read HTML content and display it in an input field is to dynamically load the content of an HTML file into the input field. This can be useful for pre-filling the input field with content from an external HTML file without hardcoding it directly into the HTML file. 

<?php
// Read the content of an HTML file
$html_content = file('example.html');

// Display the content in an input field
echo '<input type="text" value="' . implode("", $html_content) . '">';
?>
