How can PHP beginners effectively utilize functions like file_get_contents, array_slice, and echo for displaying content on a website?

To display content on a website using PHP, beginners can use functions like file_get_contents to read the contents of a file, array_slice to extract a portion of an array, and echo to output the content to the webpage. By combining these functions, beginners can efficiently retrieve content from a file, manipulate it as needed, and display it on their website. 

<?php
// Read the contents of a file
$content = file_get_contents('example.txt');

// Convert the content into an array of lines
$lines = explode("\n", $content);

// Extract a portion of the array
$subset = array_slice($lines, 0, 5);

// Output the subset of content to the webpage
foreach ($subset as $line) {
    echo $line . "<br>";
