PHP cURL adds random character in downloaded xml file - php

Question

I'm trying to access a SOAP API with PHP and for this I need to download a copy of a WSDL description file on my computer using PHP cURL.
This is the code I'm using:
<?php
$ch = curl_init();
$credit = ('some_username'.':'.'some_password');
curl_setopt($ch, CURLOPT_URL, 'https://somevalidaddress/file.asmx?WSDL');
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, $credit);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
curl_close($ch);
$path = 'C:\Wamp\www\mmx\test2.xml';
file_put_contents($path, $data);
?>
The file test2.xml contains, every time at line 345 (on a total number of 684 lines) a random character (e.g. ø, #, or VT, etc.). Also, the last character of the file is stripped.
I googled the thing and I read about Off-by-one errors and buffer overflow but still, I have no solution to my problem.
Any idea ? Thanks!

How about using this :
$context = stream_context_create(array(
'http' => array(
'header' => "Authorization: Basic " . base64_encode("$username:$password")
)
));
$data = file_get_contents('https://somevalidaddress/file.asmx?WSDL', false, $context);
