Capture Screenshot of Website from URL using PHP
Web page screenshot capture functionality is used for various purposes in the web application. There are many third party APIs are available to take a screenshot of the website. But if you wish to build your own script to get a screenshot from URL, you can do it easily using PHP using CURL.
There are many solutions to capture screenshots of Web pages. Using the Google Page Speed API is often better because internally Google uses the Chrome browser to capture exactly the way pages are presented to users, as if there was a real user seeing a given Web page. Manuel Lemos
Get Screenshot of Website from URL
To make web page snapshot, Google PageSpeed Insights API need to be called with the following params.
url:specify the URL of the website.screenshot:specify screenshot=true to retrieve the screenshot data.
<?php
$curl_init = curl_init(“[https://www.googleapis.com/pagespeedonline/v2/runPagespeed?url={$url}&screenshot=true](https://www.googleapis.com/pagespeedonline/v2/runPagespeed?url=%7B$url%7D&screenshot=true)");
curl_setopt($curl_init, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($curl_init);
curl_close($curl_init);
//call Google PageSpeed Insights API
//decode json data
$googlepsdata = json_decode($response, true);
//screenshot data
$snap = $googlepsdata[‘screenshot’][‘data’];
$snap = str_replace([‘_’, ‘-’], [‘/’, ‘+’], $snap);
echo "<img src=\"data:image/jpeg;base64,".$snap."\" />";
Capture Class
<?php
class Capture
{
/**
* Capture web screenshot using google api.
*
* [@param](http://twitter.com/param "Twitter profile for @param") (string) $url Valid url
*
* [@return](http://twitter.com/return "Twitter profile for @return") blob
*/
public function snap($url)
{
//Url value should not empty and validate url
if (!empty($url) && filter_var($url, FILTER_VALIDATE_URL)) {
$curl_init = curl_init("[https://www.googleapis.com/pagespeedonline/v2/runPagespeed?url={$url}&screenshot=true](https://www.googleapis.com/pagespeedonline/v2/runPagespeed?url=%7B$url%7D&screenshot=true)");
curl_setopt($curl_init, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($curl_init);
curl_close($curl_init);
//call Google PageSpeed Insights API
//decode json data
$googlepsdata = json_decode($response, true);
//screenshot data
$snap = $googlepsdata['screenshot']['data'];
$snap = str_replace(['_', '-'], ['/', '+'], $snap);
return $snap;
} else {
return false;
}
}
}
Usage
$snap = (new Capture())->snap('[https://zestframework.xyz'](https://zestframework.xyz%27));
if ($snap)
echo "<img src=\"data:image/jpeg;base64,".$snap."\" />";
else
echo "Enter valid url";
