Cached Results | PHP

Learn how to use ScraperAPI’s caching feature in PHP to boost speed, success rate, and efficiency. Cached results update every 10 mins for fresh data.

ScraperAPI's caching system unlocks a new level of efficiency. By leveraging advanced decision-making mechanisms, we maintain an extensive amount of cached data, that is ready to be served if called upon. When you request a page with a cached response available, you'll receive the cached data, ensuring much faster access to the information you need with a 100% success rate.

Why is this good?

• Difficult Pages: Perfect for pages that are challenging to scrape.

• 10-Minute Updates: No older than 10 minutes cached value.

• Guaranteed Success: 100% success rate for cached results.

• Faster Response Times: Retrieve data quicker from cached results.

• Fewer Retries: Reduced number of retries needed to serve back the response.

This feature applies only to requests that include the ultra_premium=true parameter and is enabled by default.

What's in it for you?

• 🚀Increased Efficiency: Save time and resources by reducing the need to scrape the same page multiple times.

• ✅Improved Reliability: Enhance the reliability of your scraping tasks with consistent and timely data retrieval.

Advanced Use-Case Scenario

For cases where real-time data is required, you can ensure the API serves uncached data by adding the parameter cache_control=no-cache to the URL, as shown below:

<?php
$url =
"https://api.scraperapi.com/?api_key=APIKEY&ultra_premium=true&cache_control=no-cache&url=http://httpbin.org/ip"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER,
TRUE); curl_setopt($ch, CURLOPT_HEADER,
FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,
0); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,
0); $response = curl_exec($ch); curl_close($ch); print_r($response);

We tag cached responses with the sa-from-cache: 1 response header, making it easy to distinguish between cached and non-cached responses.

Future Enhancements

We're always looking to improve. Stay tuned for the upcoming max_age option, which will give you even more control over your caching preferences.
