Fix for content-disposition issues on multipart forms via php://input (for instance PUT requests)

gistfile1.php

<?php
function getPostfieldsFromInput() {
	    $ct = $_SERVER['CONTENT_TYPE'];
	    $position = stripos($ct, "multipart/form-data;");
	    
	    $input = file_get_contents("php://input");
	    $postVars = array();
	    if($position !== false) {
	    
    	    $exp = explode("boundary=", $ct);
    	    if(isset($exp[1])) {
        	    $boundary = trim($exp[1]); 
        	    $variables = explode("--".$boundary, $input);
        	    foreach($variables as $var) {
            	    if(trim($var) != "" && trim($var) != "--") {	 
                        preg_match('/Content-Disposition: form-data; name="([^\"]*)"(.*)/si', $var, $result);
                        $postVars[trim($result[1])] = trim($resulta[2]);
            	    }
        	    }
    	    }
	    } else {
    	    parse_str($input, $postVars);
	    }

        return $postVars;
    }
