I am accessing images from another website. I am getting this Error:

"failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request " error when copying 'some(not all)' images. here is my code.

$img=$_GET['img']; //another website url
$file=$img;

function getFileextension($file) {
       return end(explode(".", $file));
}
$fileext=getFileextension($file);
if($fileext=='jpg' || $fileext=='gif' || $fileext=='jpeg' || $fileext=='png' || $fileext=='x-png' || $fileext=='pjpeg'){
if($img!=''){
$rand_variable1=rand(10000,100000);
              $node_online_name1=$rand_variable1."image.".$fileext;

                $s=copy($img,"images/".$node_online_name1);

}

I think preg_replace make more better sense as it will work with latest versions of the PHP as ereg_replace didn't worked for me being deprecated

$url = preg_replace("/ /", "%20", $url);

What’s the difference between a POST and a PUT HTTP REQUEST

HTTP PUT:

PUT puts a file or resource at a specific URI, and exactly at that URI. If there's already a file or resource at that URI, PUT replaces that file or resource. If there is no file or resource there, PUT creates one. PUT is idempotent, but paradoxically PUT responses are not cacheable.

HTTP 1.1 RFC location for PUT

HTTP POST:

POST sends data to a specific URI and expects the resource at that URI to handle the request. The web server at this point can determine what to do with the data in the context of the specified resource. The POST method is not idempotent, however POST responses are cacheable so long as the server sets the appropriate Cache-Control and Expires headers.

The official HTTP RFC specifies POST to be:

Annotation of existing resources;
Posting a message to a bulletin board, newsgroup, mailing list, or similar group of articles;
Providing a block of data, such as the result of submitting a form, to a data-handling process;
Extending a database through an append operation.

HTTP 1.1 RFC location for POST

Difference between POST and PUT:

The RFC itself explains the core difference:

The fundamental difference between the POST and PUT requests is reflected in the different meaning of the Request-URI. The URI in a POST request identifies the resource that will handle the enclosed entity. That resource might be a data-accepting process, a gateway to some other protocol, or a separate entity that accepts annotations. In contrast, the URI in a PUT request identifies the entity enclosed with the request -- the user agent knows what URI is intended and the server MUST NOT attempt to apply the request to some other resource. If the server desires that the request be applied to a different URI, it MUST send a 301 (Moved Permanently) response; the user agent MAY then make its own decision regarding whether or not to redirect the request.

Additionally, and a bit more concisely, RFC 7231 Section 4.3.4 PUT states (emphasis added),

4.3.4. PUT

The PUT method requests that the state of the target resource be created or replaced with the state defined by the representation enclosed in the request message payload.

Using the right method, unrelated aside:

One benefit of REST ROA vs SOAP is that when using HTTP REST ROA, it encourages the proper usage of the HTTP verbs/methods. So for example you would only use PUT when you want to create a resource at that exact location. And you would never use GET to create or modify a resource.

Rest – Is an entity body allowed for an HTTP DELETE request

The spec does not explicitly forbid or discourage it, so I would tend to say it is allowed.

Microsoft sees it the same way (I can hear murmuring in the audience), they state in the MSDN article about the DELETE Method of ADO.NET Data Services Framework:

If a DELETE request includes an entity body, the body is ignored [...]

Additionally here is what RFC2616 (HTTP 1.1) has to say in regard to requests:

an entity-body is only present when a message-body is present (section 7.2)
the presence of a message-body is signaled by the inclusion of a Content-Length or Transfer-Encoding header (section 4.3)
a message-body must not be included when the specification of the request method does not allow sending an entity-body (section 4.3)
an entity-body is explicitly forbidden in TRACE requests only, all other request types are unrestricted (section 9, and 9.8 specifically)

For responses, this has been defined:

whether a message-body is included depends on both request method and response status (section 4.3)
a message-body is explicitly forbidden in responses to HEAD requests (section 9, and 9.4 specifically)
a message-body is explicitly forbidden in 1xx (informational), 204 (no content), and 304 (not modified) responses (section 4.3)
all other responses include a message-body, though it may be of zero length (section 4.3)
