How do I access PHP REST API PUT data on the server side?

I've the same scenario where in, have to send data to the PHP Server through ReST API using the PUT method. I struggled almost couple of hours to find the solution, but finally found the way :

In CUrl :

$postData = http_build_query($data);
curl_setopt($ch, CURLOPT_POSTFIELDS,$postData); 

We've to parse the data to a variable let say: $putData, Here, is the Parse String procedure :

parse_str(file_get_contents("php://input"),$putData); 

Then print the $putData, will get the same array that you're posting in the curl..

From the PHP Manual:

PUT data comes from stdin:

$putdatafp = fopen("php://input", "r");

Example usage:

$putfp = fopen('php://input', 'r');
$putdata = '';
while($data = fread($putfp, 1024))
    $putdata .= $data;
fclose($putfp);

If you want to get form data with key value like $_POST.

function PUT(string $name):string{

    $lines = file('php://input');
    $keyLinePrefix = 'Content-Disposition: form-data; name="';

    $PUT = [];
    $findLineNum = null;

    foreach($lines as $num => $line){
        if(strpos($line, $keyLinePrefix) !== false){
            if($findLineNum){ break; }
            if($name !== substr($line, 38, -3)){ continue; }
            $findLineNum = $num;
        } else if($findLineNum){
            $PUT[] = $line;
        }
    }

    array_shift($PUT);
    array_pop($PUT);

    return mb_substr(implode('', $PUT), 0, -2, 'UTF-8');

}

For Example rest-api.php

$title = PUT('title');
