How to Create a News Aggregator Using PHP (Step-by-Step Guide)

Introduction

Want to collect news from multiple websites automatically? In this guide, you will learn how to build a PHP news aggregator step by step. This real-world project will help you understand how to fetch and combine data from multiple sources.

What is a News Aggregator?

A news aggregator collects articles from different websites and displays them in one place. It is widely used in news apps, dashboards, and monitoring tools.

How PHP News Aggregator Works

The process involves fetching multiple web pages, extracting article titles, and displaying them together.

Step 1: Define News Sources

<?php
$urls = [
    "https://books.toscrape.com/",
    "https://realpython.github.io/fake-jobs/"
];
?>

Step 2: Fetch Data Using cURL

<?php
function fetchData($url) {
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0");

    $response = curl_exec($ch);
    curl_close($ch);

    return $response;
}
?>

Step 3: Parse and Extract Titles

<?php
function extractTitles($html) {
    $dom = new DOMDocument();
    @$dom->loadHTML($html);

    $xpath = new DOMXPath($dom);
    $titles = $xpath->query("//h3/a");

    $data = [];
    foreach ($titles as $title) {
        $data[] = $title->getAttribute("title");
    }

    return $data;
}
?>

Step 4: Combine Results

<?php
$allTitles = [];

foreach ($urls as $url) {
    $html = fetchData($url);
    $titles = extractTitles($html);
    $allTitles = array_merge($allTitles, $titles);
}

foreach ($allTitles as $item) {
    echo $item . "<br>";
}
?>
