How to download this PDF file using php - php

Question

I want to download a pdf file from this link. From the page, select weekly summary, I want download the first pdf.
PDF Weekly summary - Last week: Sorted by insider
I'm using the following code try to download the pdf,
<?php
$file="https://www.sedi.ca/sedi/SVTWeeklySummaryACL?name=W1ALLPDFI&locale=en_CA";
if (file_exists($file))
{
if (FALSE!== ($handler = fopen($file, 'r')))
{
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: chunked'); //changed to chunked
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
//header('Content-Length: ' . filesize($file)); //Remove
//Send the content in chunks
while(false !== ($chunk = fread($handler,4096)))
{
echo $chunk;
}
}
exit;
}
echo "<h1>Content error</h1><p>The file does not exist!</p>";
?>
It seems I can not download using PHP. I can download by myself confirm the popup window. Any suggestions?
I tried curl also, still can not download. The file size is zero.
<?php
$file="https://www.sedi.ca/sedi/SVTWeeklySummaryACL?name=W1ALLPDFI&locale=en_CA";
$path = 'c:\download\output.pdf';
$ch = curl_init($file);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
curl_close($ch);
file_put_contents($path, $data);
?>

Finally I could download the PDF file with PHP curl and CURLOPT_REFERER setting. Below is the code.
<?php
$url = 'https://www.sedi.ca/sedi/SVTWeeklySummaryACL?name=W1ALLPDFI&locale=en_CA';
$path = "/pdf/output.pdf";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_REFERER, 'https://www.sedi.ca/sedi/SVTReportsAccessController?menukey=15.03.00&locale=en_CA');
$data = curl_exec($ch);
curl_close($ch);
$result = file_put_contents($path, $data);
if (!$result) {
echo "error";
} else {
echo "success";
}
?>

Instead of getting your PHP server to act as a proxy why not just:
<?PHP
$file="https://www.sedi.ca/sedi/SVTWeeklySummaryACL?name=W1ALLPDFI&locale=en_CA";
header("Location: $file");
?>
Version 2
<?PHP
$file="https://www.sedi.ca/sedi/SVTWeeklySummaryACL?name=W1ALLPDFI&locale=en_CA";
header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="filename.pdf"');
readfile($file);
?>
Version 3
curl_setopt($ch, CURLOPT_REFERER, 'https://www.sedi.ca/sedi/SVTWeeklySummaryACL?name=W1ALLPDFI&locale=en_CA');
Add this line to your original code?

Also, as mentioned here:
Download a image from SSL using curl?
for https we should add the following:
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
