PHP Exercises : Display source code of a webpage

PHP : Exercise-14 with Solution

Write a PHP script to display source code of a webpage (e.g. "http://www.example.com/").

Webpage: A web page is a document that is suitable for the World Wide Web and web browsers. A web browser displays a web page on a monitor or mobile device.

The web page usually means what is visible, but the term may also refer to a computer file, usually written in HTML or a comparable markup language. Web browsers coordinate various web resource elements for the written web page, such as style sheets, scripts, and images, to present the web page.

Sample Solution:

PHP Code:

<?php
// Read all lines from the specified URL and store them in an array
$all_lines = file('https://www.w3resource.com/');

// Iterate through each line in the array
foreach ($all_lines as $line_num => $line)
{
    // Display the line number and the HTML-escaped content of the line
    echo "Line No.-{$line_num}: " . htmlspecialchars($line) . "\n";
}
?>

Sample Output:

View the output in the browser
