“Instantly convert curl commands to PHP code”

Whicvhever cURL you have in command line, you can convert it to PHP with this tool:

https://incarnate.github.io/curl-to-php/

It helped me after long long hours of searching for a solution! Hope it will help you out too! Your solution is this:

// Generated by curl-to-PHP: http://incarnate.github.io/curl-to-php/
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "http://hostname/@api/deki/pages/=TestPage/files/=test.png");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$post = array(
    "file" => "@" .realpath("test.png")
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");


$headers = array();
$headers[] = "Content-Type: image/png";
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$result = curl_exec($ch);
if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}
curl_close ($ch);

Try this:

$cmd='curl -b cookie.txt -X PUT \
     --data-binary "@test.png" \
     -H "Content-Type: image/png" \    
     "http://hostname/@api/deki/pages/=TestPage/files/=test.png" \
     -0';
exec($cmd,$result);

Note that this only lists somewhat exact matches of –long options to similarly named CURLOPT_ constants. But it should give you enough hints on how to compare the curl --help output and the PHP curl_setopt() list.

the –libcurl option was added for this purpose, even though it makes a C program I think it should be fairly easy to translate to PHP

Using MYYN’s answer as a starting point, and this page as a reference on how to send POST data using PHP cURL, here is my suggestion (I am working on something very similar at the moment):

<?php

$pageurl = "http://hostname/@api/deki/pages/=TestPage/files/=";
$filename = "test.png";

$theurl = $pageurl.$filename;

$ch = curl_init($theurl);
curl_setopt($ch, CURLOPT_COOKIE, ...); // -b
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT'); // -X
curl_setopt($ch, CURLOPT_BINARYTRANSFER, TRUE); // --data-binary
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: image/png']); // -H
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0); // -0

$post = array("$filename"=>"@$filename");
curl_setopt($ch, CURLOPT_POSTFIELDS, $post); 
$response = curl_exec($ch);
?>

You can probably optimize the many curl_setopts with the use of a curl_setopt_array() call if you desire.

Better this. In one line.

$cmd='curl -b cookie.txt -X PUT --data-binary "@test.png" -H "Content-Type: image/png" "http://hostname/@api/deki/pages/=TestPage/files/=test.png" -0';
exec($cmd,$result);
