問題從GA餅乾

Question

即時通訊目前有一些麻煩提取從cookie我只想關鍵字的關鍵字提取的關鍵字就是所有繼承人我的代碼：

function parse_ga_cookie($cookie) 
{ 

$values = sscanf($cookie, '%d.%d.%d.%d.utmcsr=%[^|]|utmccn=%[^|]|utmcmd=%[^|]|utmctr=%[^|]'); 

    if (count($values) !== 8) { 
     // return false; trigger_error(...); ... or whatever you like 
     throw new InvalidArgumentException("Cookie value '$cookie' does not conform to the __utmz pattern"); 

    } 
    $keys = array('domain', 'timestamp', 'visits', 'sources', 'campaign', 'source', 'medium', 'keyword'); 

    return array_combine($keys, $values); 

} 

print_r(parse_ga_cookie($_COOKIE['__utmz'])); 

這會給所有的按鍵，但如果我只打印關鍵字它只會給我陣列（）：/

function parse_ga_cookie($cookie) 
{ 

$values = sscanf($cookie, '%d.%d.%d.%d.utmcsr=%[^|]|utmccn=%[^|]|utmcmd=%[^|]|utmctr=%[^|]'); 

    if (count($values) !== 8) { 
     // return false; trigger_error(...); ... or whatever you like 
     throw new InvalidArgumentException("Cookie value '$cookie' does not conform to the __utmz pattern"); 

    } 
    $keys = array('domain', 'timestamp', 'visits', 'sources', 'campaign', 'source', 'medium', 'keyword'); 

    return array_combine($keys, $values); 

} 

$keyword=parse_ga_cookie($_COOKIE['__utmz']); 
$keyword=$keyword['keyword'];
