PHP uses curl not rely on cookiejar to get cookies

The example in this article describes how PHP uses curl to get cookies without relying on cookiejar. Share to everyone for your reference. The specific analysis is as follows:

PHP Curl class is a very good tool class, the specific how to not verbose.

It also has good support for the Cookie,curl class, but it is not flexible enough to be obtained by means of a variable method, and is implemented in the following ways.

3//Save Cookies to Cookie.txt

curl_setopt ($ch, Curlopt_cookiefile, ' cookie.txt ');

curl_setopt ($ch, Curlopt_cookiejar, ' cookie.txt ');

Save the cookie file for the first time, and read the file when it is called, which means two IO operations and how efficient it is, needless to say, everyone knows.

So is there a way to bypass the read file? Suspense, directly on the code:

$ch = Curl_init ();

curl_setopt ($ch, Curlopt_url, $url);

Get header information

curl_setopt ($ch, Curlopt_header, 1);

Returns the raw (RAW) output

curl_setopt ($ch, Curlopt_returntransfer, true);

Execute and get the return result

$content = curl_exec ($ch);

Close Curl

Curl_close ($ch);

Parsing HTTP data streams

List ($header, $body) = Explode ("Rnrn", $content);

Parsing cookies

Preg_match ("/set-cookie: ([^rn]*)/I", $header, $matches);

It can be used directly after submitting with curl.

curl_setopt ($ch, Curlopt_cookie, $cookie);

$cookie = $matches [1];
