I would like to add several values that I webscrape to a final result array. Each value that I scrape represents a column in the array.

See below what I tried:

<?php require_once 'vendor/autoload.php'; use GoutteClient; $client = new Client(); $cssSelector = 'tr'; $coin = 'td.no-wrap.currency-name > a'; $url = 'td.no-wrap.currency-name > a'; $symbol = 'td.text-left.col-symbol'; $price = 'td:nth-child(5) > a'; $result = array(); $crawler = $client->request('GET', 'https://coinmarketcap.com/all/views/all/'); $crawler->filter($coin)->each(function ($node) { print $node->text()."n"; array_push($result, $node->text()); }); $crawler->filter($url)->each(function ($node) { $link = $node->link(); $uri = $link->getUri(); print $uri."n"; array_push($result, $uri); }); $crawler->filter($symbol)->each(function ($node) { print $node->text()."n"; array_push($result, $node->text()); }); $crawler->filter($price)->each(function ($node) { print $node->text()."n"; array_push($result, $node->text()); }); print_r($result);

My problem is that the individual results do not get pushed to the array. Any suggestions why?

Is there a better method to add multiple attributes to an array?

I appreciate your replies!

Answer

$result is not known in your closure.

try USE to include the external variable $result within the filter-closure, like so :

$crawler->filter($coin)->each(function ($node) use (&$result) { print $node->text()."n"; array_push($result, $node->text()); });
