What is the cURL -T option in PHP - php

Question

I'm trying to post to a file service with CDN translating the cli -T option to PHP code, but I don't really know what the equivalent is, or what is the corresponding code that would replicate it. I've seen a options around CURLOPT_HTTPHEADER, but that doesn't seem to work in correspondence to other headers.
The exact thing I'm trying to replicate is this:
curl -XPUT -T "test.png" -v -H "X-Auth-Token:MYTOKEN" -H"Content-Type: text/plain" "https://somecdn.com"
I think it's something like this, but I'm unsure:
$ch = curl_init();
// Set up the options
curl_setopt($ch, CURLOPT_URL, "https://mycdn.com/test.txt");
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
"X-Auth-Token: mytoken",
"Content-type: text/plain"
)
);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, array("file" => "#test.txt") );
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
I'm surprised, I suppose, that -T flag doesn't have a similar curl_setopt.
So the precise question is this:
What is the proper way to replicate cURL CLI -T "test.png" in PHP?

Answer 1

Take into consideration as PHP 5.5 uploading file this way (#filename) is deprecated.
Also, PHP 5.5 introduces a new option/flag regarding upload process, called by CURLOPT_SAFE_UPLOAD:
TRUE to disable support for the # prefix for uploading files in
CURLOPT_POSTFIELDS, which means that values starting with # can be
safely passed as fields. CURLFile may be used for uploads instead.
Added in PHP 5.5.0 with FALSE as the default value. PHP 5.6.0 changes
the default value to TRUE.
So if you've PHP 5.5+ you must set CURLOPT_SAFE_UPLOAD (though 5.5 is false by default) to false:
curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);
Another option is using the CURLFile class.
And remember: Filename MUST be absolute path.
