help on using curl

[shotokan99]

hi,
i wanted to accomplish these task:


1. from that webservice get a certain set of strings from the header
2. next, generate the image.

and these 2 steps will be done at the same time.

to get the header value:
$ch = curl_init();
$timeout = 0;
curl_setopt ($ch, CURLOPT_URL, $xmyurl);
curl_setopt($ch, CURLOPT_HEADER, 1);

ob_start();
curl_exec($ch);
$s=ob_get_contents();

now from the same url i want also to generate the image on the file.
if just to create the image:

$ch = curl_init();
$timeout = 0;
curl_setopt ($ch, CURLOPT_URL, $xmyurl);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
// Getting binary data
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);

$image = curl_exec($ch);
curl_close($ch);
now...how to combine both functions?

these are two tasks:

first get the string with cURL
second create the dynamic image with imagemagick or GD

how to get the string with curl? can you give me a sample? because when i tried putting all things together:

ch = curl_init();
$timeout = 0;
curl_setopt ($ch, CURLOPT_URL, $xmyurl);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
ob_start();
curl_exec($ch);
$s=ob_get_contents();
.
.
.

i cant get the image. is there a way for me to do it with curl without using imagemagick. yes we do have gd and im applying it in creating the image on the fly.

after getting the page you need to parse the image information, check this tutorial:

note that cURL is only a function to get a remote file (thats all)

if you don't like IM use the GD library, but there is no way to do that job with cURL only.
