Create Google Alert and grab the feed.

A.README

Google alerts is a way to manage your content by subscribing to keywords. Here is an example on how to make that google alert with php.

Get the feed url and parse the feed. There won't be any feed available as soon the alert is created.

-------------------------------------

Copy composer.json and do composer update.

Add this to providers

    		'Awjudd\FeedReader\FeedReaderServiceProvider', 

Add this to aliases

            	'FeedReader'      => 'Awjudd\FeedReader\Facades\FeedReader',

Add route to routes.php.

Copy GAlerts.php in app/helpers folder. 

Then make app/start/global.php look like following:

ClassLoader::addDirectories(array(

	app_path().'/commands',
	app_path().'/controllers',
	app_path().'/models',
	app_path().'/database/seeds',
	app_path().'/helpers',

));

}

C.routes.php

<?php 

Route::get('galert',function(){

	$Ga = new GAlerts();

	$result = $Ga->createAlert('A R Rahman');

        var_dump($result);

	$feed = FeedReader::read($result);

	foreach ($feed->get_items() as $item) {

		echo '<pre>';
		echo $item->get_link().'<br>';
		echo $item->get_title().'<br>';
		echo $item->get_description().'<br>';
		echo $item->get_date().'<br>';
		echo $item->get_id().'<br>';
		echo $item->get_feed().'<br>';
		echo '</pre>';
		echo '<br>';

		$result = explode('?q=',$item->get_link())[1];

		$result = explode('&',$result)[0];
 		
 		echo $result;

 		echo file_get_contents($result);

		echo '<br>-----------------------------------------<br>';

This url does not exit. It should also be https:

I believe curl won't work as the site looks to be Ajax.

Hi @rajivseelam and @theodis, This code is not working for me (error always: login failed). Do you have same problem?

Agree with @djeraseit
