Convert command line cURL to PHP cURL

Question

I've never done any curl before so am in need of some help. I've tried to work this out from examples but cannot get my head around it!

I have a curl command that I can successfully run from a linux(ubuntu) command line that puts a file to a wiki through an api.

I would need to incorporate this curl command in a PHP script I'm building.

How can I translate this curl command so that it works in a PHP script?

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

cookie.txt contains the authentication but I don't have a problem putting this in clear text in the script as this will be run by me only.

@test.png must be a variable such as $filename

http://hostname/@api/deki/pages/=TestPage/files/= must be a variable such as $pageurl

Thanks for any help.

Answer 1

a starting point:

<?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

...
?>

You need ...

Answer 3

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);

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.

Answer 5

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);

Answer 6

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

Answer 7

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.

Answer 8

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);
