Download Campaign Performance Reports using Bings Ads in PHP - php

Question

I was struck in this since a weeks. Please tell me if any one can help me out from this.
I tried this samples they given. I'm trying to download only campaign performance reports, Where i'm able to download a zip file which has a csv file in it. Here is the another direct example i followed for keywords and did the same way for campaign performance. Which giving me a link to download the reports. When i'm trying to download the url manually i can download but I cannot download it through my code.
function DownloadFile($reportDownloadUrl, $downloadPath) {
if (!$reader = fopen($reportDownloadUrl, 'rb')) {
throw new Exception("Failed to open URL " . $reportDownloadUrl . ".");
}
if (!$writer = fopen($downloadPath, 'wb')){
fclose($reader);
throw new Exception("Failed to create ZIP file " . $downloadPath . ".");
}
$bufferSize = 100 * 1024;
while (!feof($reader)) {
if (false === ($buffer = fread($reader, $bufferSize))) {
fclose($reader);
fclose($writer);
throw new Exception("Read operation from URL failed.");
}
if (fwrite($writer, $buffer) === false) {
fclose($reader);
fclose($writer);
$exception = new Exception("Write operation to ZIP file failed.");
}
}
fclose($reader);
fflush($writer);
fclose($writer);
}
But I couldn't download the file. I can't move forward from there so any help like downloading reports in any-other form or the simple code changes in current method is greatly appreciated. Thanks in advance.

When I tried this I also had problems with the DownloadFile function so replaced this with a different version
function DownloadFile($reportDownloadUrl, $downloadPath) {
$url = $reportDownloadUrl;
// Example for the path would be in this format
// $path = '/xxx/yyy/reports/keywordperf.zip';
// using the server path and not relative to the file
$path = $downloadPath;
$fp = fopen($path, 'w');
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_SSLVERSION, 3);
curl_setopt($ch, CURLOPT_FILE, $fp);
if($result = curl_exec($ch)) {
$status = true;
}
else
{
$status = false;
}
curl_close($ch);
fclose($fp);
return status;
}
