Some data may be lost", E_USER_WARNING); } setcookie("$this->_name", $cookie_val, $this->_expires, $this->_dir, $this->_site); } } ?> 調用樣本：1，設定cookie put("namefirst","Jo");$PHP_COOKIE->put("namelast","Foo");$PHP_COOKIE->put("number","1234");$PHP_COOKIE->put("time",time()); // Set the cookie$PHP_COOKIE->set();$PHP_COOKIE=new PHP_COOKIE("test_cookie 123");// Add the variables to be saved in the cookie$PHP_COOKIE->put("namefirst","Jo123");$PHP_COOKIE->put("namelast","Foo13");$PHP_COOKIE->put("number","123413"); // Set the cookie$PHP_COOKIE->set();echo " The values saved in the cookie test_cookie are:";echo " namefirst: = $_COOKIE[namefirst]";echo " namelast: = $_COOKIE[namelast]";echo " number: = $_COOKIE[number]";echo " time: = $_COOKIE[time]";echo " END";?> 2，擷取cookie 顯示用於測試的一些cookie值" ;echo " Name: ";echo $_COOKIE['namefirst']; echo " ";echo $_COOKIE['namelast'];echo " Number: ";echo $_COOKIE['number'];echo " Time: ";echo $_COOKIE['time'];echo " END";?> 3，刪除cookie set();// Clear all values#$PHP_COOKIE->clear();?>
