Using Smart Proxy Manager with PHP#

Warning

zyte-smartproxy-ca.crt should be installed in your OS for the below code to work. You can follow these instructions in order to install it.

Note

All the code in this documentation has been tested with PHP 7.3.29 and guzzlehttp/guzzle 7.3.0.

Using Curl#

Making use of PHP binding for libcurl:

<?php

$ch = curl_init();

$url = 'https://httpbin.scrapinghub.com/get';
$proxy = 'proxy.zyte.com:8011';
$proxy_auth = '<API KEY>:';

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxy_auth);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_TIMEOUT, 180);
curl_setopt($ch, CURLOPT_CAINFO, '/path/to/zyte-smartproxy-ca.crt'); //required for HTTPS
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1); //required for HTTPS

$scraped_page = curl_exec($ch);

if($scraped_page === false)
{
    echo 'cURL error: ' . curl_error($ch);
}
else
{
    echo $scraped_page;
}

curl_close($ch);

?>

Please be sure to download the certificate provided in your Smart Proxy Manager account and set the correct path to the file in your script.

Refer to curl_multi_exec function to take advantage of Smart Proxy Manager’s concurrency feature and process requests in parallel (within the limits set for a given Smart Proxy Manager plan).

Using Guzzle#

A Guzzle example:

<?php

use GuzzleHttp\Client as GuzzleClient;

$proxy_host = 'proxy.zyte.com';
$proxy_port = '8011';
$proxy_user = '<API KEY>';
$proxy_pass = '';
$proxy_url = "http://{$proxy_user}:{$proxy_pass}@{$proxy_host}:{$proxy_port}";

$url = 'https://httpbin.org/headers';

$guzzle_client = new GuzzleClient();
$res = $guzzle_client->request('GET', $url, [
    'proxy' => $proxy_url,
    'headers' => [
        'X-Crawlera-Cookies' => 'disable',
        'Accept-Encoding' => 'gzip, deflate, br',
    ]
]);

echo $res->getBody();

?>
