Question

这是$result返回的内容：

HTTP/1.1 200 OK

我想从响应中检索KEY Cookie。目前我的代码如下

//a cURL function would be here
$result = curl_exec($ch); 

list($body, $split) = explode("\r\n\r\n", $result, 2);
$arr = explode("\r\n", $body);   

$start = explode(":", $arr[10]);    
$end = explode(";", $start[1]);
$INFO_I_NEED = $end[0];

执行此操作的简单方法是什么？因为对于不同的解析区域需要完成3/4次。

Answer 1

看起来preg_match_all可能就是您要找的东西。使用this answer作为灵感尝试：

preg_match_all('/^Set-Cookie:\s*([^;]*)/mi', $result, $m);

然后您可以编写如下函数：

function getCookies($result) {
    preg_match_all('/^Set-Cookie:\s*([^;]*)/mi', $result, $m);
    return($m)
}

$result = curl_exec($ch);
$cookiesArray = getCookies($result);

函数的返回值将是所有cookie值的数组。因此$cookiesArray将成立：

array (
  0 => 'KEY=isbgvigbiwsb124252525252',
  1 => 'session=12345566789:abc1231552662626262',
)

Answer 2

将它放在一个函数中，以便在需要时重用：

<?php
//a cURL function would be here
$result = curl_exec($ch); 

$INFO_I_NEED = myExplode($result);

function myExplode($data){

    list($body, $split) = explode("\r\n\r\n", $result, 2);
    $arr = explode("\r\n", $body);   

    $start = explode(":", $arr[10]);    
    $end = explode(";", $start[1]);

    return($end[0]);

}
?>

如何从原始HTTP响应中检索特定的头字段？
