Write cookie

}

The code is as follows

setcookie(name, value, expire, path, domain); function w_cookie($n, $c, $e = 0,$isdes=1)  {    if($isdes==1){$c=endes($c,deskey);}       $exp = time() + 3600 * 24 * 30;       if($e == 0)      {           setcookie($n, $c, $exp,"/");      }      else      {       setcookie($n, $c,0,"/");       }  }

Copy code

setcookie(name, value, expire, path, domain);

function w_cookie($n, $c, $e = 0,$isdes=1)

{

if($isdes==1){$c=endes($c,deskey);}

$exp = time() + 3600 * 24 * 30;

代码如下	复制代码
function cookie($var, $value='', $time=0, $path='', $domain=''){ $_COOKIE[$var] = $value;   if(is_array($value)){       foreach($value as $k=>$v){         setcookie($var.'['.$k.']', $v, $time, $path, $domain, $s);       }   }else{         setcookie($var, $value, $time, $path, $domain, $s);   } }   //调用方法   cookie("website","安卓主题","./","www.hzhuti.com"); //

If($e == 0)

{

​​​​​ setcookie($n, $c, $exp,"/");

}

      else

代码如下	复制代码
$time = time() + 300;    //5分钟过期 $code = md5($string . $time . $salt); setcookie('check_time', $time); setcookie('code', $code); //验证部分 $TIME = time(); if($check_time < $TIME)//如果服务器时间比验证时间大，算过期 //expire过期 if(md5($string . $check_time . $salt) !== $code)

{

setcookie($n, $c,0,"/");

}

The way to turn off cookies is to set them to expire. Example 1 Write cookie

The code is as follows

Copy code

function cookie($var, $value='', $time=0, $path='', $domain=''){ $_COOKIE[$var] = $value; if(is_array($value)){

foreach($value as $k=>$v){           setcookie($var.'['.$k.']', $v, $time, $path, $domain, $s);

}

}else{           setcookie($var, $value, $time, $path, $domain, $s); } } //Call method cookie("website","Android theme","./","www.hzhuti.com"); // Example 2 Prevent duplicate submissions

The code is as follows

Copy code

$time = time() + 300; //Expires in 5 minutes $code = md5($string . $time . $salt); setcookie('check_time', $time); setcookie('code', $code); //Verification part $TIME = time(); if($check_time < $TIME)//If the server time is greater than the verification time, it is considered expired //expire expires   if(md5($string . $check_time . $salt) !== $code) For more information about php cookie usage, please refer to: http://www.bKjia.c0m/tags.php/php%20cookie/ http://www.bkjia.com/PHPjc/628924.htmlwww.bkjia.comtruehttp: //www.bkjia.com/PHPjc/628924.htmlTechArticleCookie is a small file sent on the browser side, which can be used to record user operations, such as visits Those files, etc. are written into cookies.
