How to pass cookies in PHP CURL

How to use curl’s cookies? It’s a headache for novices. There are too many parameters in curl, of which the cookie part involves 4.

Of course, the manual clearly states that curl has 3 cookies, but there is also a header parameter, which can contain cookies.

curl is very easy to use. The most important thing is to be familiar with the usage of curl_setopt.

curl_setopt ($ch, CURLOPT_COOKIE , $cookie );

The cookie values ​​here should be separated with; instead of &. There is no need to use urlencode encoding, of course, it would be better if encoded.

$cookie = "a=b;c=d;name=Fang Shiyu";

Please note that when using this, you cannot include Cookie parameters in the $header of curl_setopt ($ch, CURLOPT_HTTPHEADER, $header);

. Otherwise, they will overlap and cause unpredictable cookie behavior.

<? php
$url = "http://www.test.com/zzzz.php";
$post_data = array (
    "foo" =< "bar",
    "query" =< "Nettuts",
    "action" =< "Submit"
);
$cookie_jar_index = &#39;f:/js/test/cookie.txt&#39;;
$cookie = "a=b;c=d;name=方世玉";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// 我们在POST数据哦！
curl_setopt($ch, CURLOPT_POST, 1);
// 把post的变量加上
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_COOKIE, $cookie);
$output = curl_exec($ch);
curl_close($ch);
echo $output;

Attached is the code used to analyze cookies in IE

<? php
function join_cookie($cook)
{
    foreach( $cook as $k=<$v )
    {
   $d[] =$k."=".$v;
    }
$data = implode(";",$d);
return $data;
}
function pase_cookie($cookFile,$encode=true)
{
$cookie = file_get_contents ( $cookFile );
$citem = explode("*\n",$cookie);
foreach( $citem as $c )
{
list($ckey,$cvalue) = explode("\n",$c);
if($ckey!=&#39;&#39;)$cook[$ckey] = $cvalue;
}
return $cook;
}
