Curl, not getting page source code - php

Question

In this script curl is working fine. $output has the page but when I try to echo its source code it displays nothing. I think it has something to do with page headers. Any help!!
header('content-type:text/plain');
$ch = curl_init();
$url = "https://www.amazon.com/gp/css/shiptrack/view.html/ref=TE_SIMP_typ?ie=UTF8&addressID=olqnkqjstjp&latestArrivalDate=1483848000&orderID=103-0753412-5410653&shipmentDate=1483706902&orderingShipmentId=4160817392100&packageId=1";
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_BINARYTRANSFER, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_MAXREDIRS, 1);
$output = curl_exec($ch);
curl_close($ch);
echo $output;

I have modified your code..
Try this.
Remove
header('content-type:text/plain');
and replace your code with mine.
$ch = curl_init();
$url = "https://www.amazon.com/gp/css/shiptrack/view.html/ref=TE_SIMP_typ?ie=UTF8&addressID=olqnkqjstjp&latestArrivalDate=1483848000&orderID=103-0753412-5410653&shipmentDate=1483706902&orderingShipmentId=4160817392100&packageId=1";
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_MAXREDIRS, 1);
$output = curl_exec($ch);
curl_close($ch);
echo $output;
EDIT
Since you want ctrl+u
Here is the PHP code to fetch the html source code of any website specified. fopen function is used to open the website URL. stream_get_contents is used to read the opened URL. The fetched code is displayed inside a textarea.
$domain = 'https://www.amazon.com/gp/css/shiptrack/view.html/ref=TE_SIMP_typ?ie=UTF8&addressID=olqnkqjstjp&latestArrivalDate=1483848000&orderID=103-0753412-5410653&shipmentDate=1483706902&orderingShipmentId=4160817392100&packageId=1';
$handle = fopen($domain, 'r');
$content = stream_get_contents($handle);
/**
// alternative to stream_get_contents
$contents = '';
while (!feof($handle)) {
$content .= fread($handle, 8192);
}
**/
fclose($handle);
/**
* print html content on textarea
*/
echo "<textarea rows='20' cols='80'>$content</textarea>";
output will be like this:

Also if you want to manipulate the retrieved page somehow, you might
want to try some php DOM parser. I find PHP Simple HTML DOM
Parser very easy to use.
