PHP Code Examples

The following are code examples on how to integrate the ScrapeOps Proxy Aggregator with your PHP based web scrapers using cURL library.

Authorisation - API Key

To use the ScrapeOps proxy, you first need an API key which you can get by signing up for a free account here.

Your API key must be included with every request using the api_key query parameter otherwise the API will return a 403 Forbidden Access status code.


Basic Request

The following is some example PHP code to send a URL to the ScrapeOps Proxy endpoint https://proxy.scrapeops.io/v1/.


<?php

$api_key = 'YOUR_API_KEY';
$url = 'http://httpbin.org/ip';
$proxy_url = 'https://proxy.scrapeops.io/v1/';
$encodedUrl = urlencode($url);

$fullURL = $proxy_url . '?api_key=' . $api_key . '&url=' . $encodedUrl;


$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $fullURL);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 120);

$response = curl_exec($ch);

if (curl_errno($ch)) {
echo 'Error: ' . curl_error($ch);
} else {
echo 'Body: ' . $response;
}

curl_close($ch);

?>

ScrapeOps will take care of the proxy selection and rotation for you so you just need to send us the URL you want to scrape.

If you want to send multiple requests and manage concurrency we suggest you use a HTTP client such as [Guzzle] (https://github.com/guzzle/guzzle). This is easier to use and helps you to use asynchronous requests in a simple manner.


Response Format

After recieving a response from one of our proxy providers the ScrapeOps Proxy API will then respond with the raw HTML content of the target URL along with a response code:


<html>
<head>
...
</head>
<body>
...
</body>
</html>

The ScrapeOps Proxy API will return a 200 status code when it successfully got a response from the website that also passed response validation, or a 404 status code if the website responds with a 404 status code. Both of these status codes are considered successful requests.

Here is the full list of status codes the Proxy API returns.


Advanced Functionality

To enable other API functionality when using the Proxy API endpoint you need to add the appropriate query parameters to the ScrapeOps Proxy URL.

For example, if you want to enable Javascript rendering with a request, then add render_js=true to the request url:


<?php

$api_key = 'YOUR_API_KEY';
$url = 'http://httpbin.org/ip';
$proxy_url = 'https://proxy.scrapeops.io/v1/';
$encodedUrl = urlencode($url);


$fullURL = $proxy_url . '?api_key=' . $api_key . '&url=' . $encodedUrl . '&render_js=true';


$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $fullURL);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 120);

$response = curl_exec($ch);

if (curl_errno($ch)) {
echo 'Error: ' . curl_error($ch);
} else {
echo 'Body: ' . $response;
}

curl_close($ch);

?>

Timeout

The ScrapeOps proxy keeps retrying a request for up to 2 minutes before returning a failed response to you.

To use the Proxy correctly, you should set the timeout on your request to a least 2 minutes to avoid you getting charged for any successful request that you timed out on your end before the Proxy API responded.
