Measure page load time

You can use the following PHP code to measure page load time using Google PageSpeed Insights API:

	private static function getPageSpeedInsights($url) {
	$apiUrl = "https://www.googleapis.com/pagespeedonline/v5/runPagespeed";
	/*$queryParams = http_build_query([
	'url' => $url,
	'key' => 'YOUR_API_KEY' // If you plan on using the API in an automated way and making multiple queries per second, you'll need an API key
	]);*/
	$queryParams = http_build_query([
	'url' => $url
	]);
	$ch = curl_init("$apiUrl?$queryParams");
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
	$response = curl_exec($ch);
	curl_close($ch);
	return json_decode($response, true);
	}
	private static function measurePageLoadTime() {
	echo "<h2>TEST measurePageLoadTime</h2>";
	$url = "url of website you want to measure";
	echo "Started measurePageLoadTime for $url...<br>";
	//Display the above message immediately, without waiting for operations to finish:
	ob_flush();
	flush();
	$start_time = microtime(true);
	$result = self::getPageSpeedInsights($url);
	$end_time = microtime(true);
	if (isset($result['lighthouseResult']['audits']['first-contentful-paint']['displayValue'])) {
	$fcpValue = $result['lighthouseResult']['audits']['first-contentful-paint']['displayValue'];
	echo "First Contentful Paint: $fcpValue";
	} else {
	echo "First Contentful Paint data not available.";
	}
	echo "<br>Total time [s]: " . number_format($end_time - $start_time, 2) . "<br>";
	}
