一直在尋找一種方法來解析像private, max-age=86400字符串轉換成一個這樣的數組：

[private] => TRUE 
[max-age] => 86400

/** 
* Parse the cache-control string into a key value array. 
* 
* @param string $cache_control 
* The cache-control string. 
* 
* @return array 
* Returns a key value array. 
*/ 
function parse_cache_control($cache_control) { 
    $cache_control_array = explode(',', $cache_control); 
    $cache_control_array = array_map('trim', $cache_control_array); 
    $cache_control_parsed = array(); 
    foreach ($cache_control_array as $value) { 
    if (strpos($value, '=') !== FALSE) { 
     $temp = array(); 
     parse_str($value, $temp); 
     $cache_control_parsed += $temp; 
    } 
    else { 
     $cache_control_parsed[$value] = TRUE; 
    } 
    } 
    return $cache_control_parsed; 
}
