checkdumpnbspquotvalidation

本文章提供的确款正则表达式来检测url地址，日期格式，ip地址，与邮箱地址是否合法的验证代码,希望本文章对各位同学会带来帮助。

代码如下

复制代码

class validation{
function check_email($value){ //check a email address
  return (bool) preg_match('/^[a-z0-9._%+-]+@(?:[a-z0-9-]+.)+[a-z]{2,4}$/i', $value);
}

function check_ip($value){ //check a ip address
  return (bool) preg_match("/^(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).){4}$/", $value.".");
}

function check_date($date, $format="dd/mm/yy"){ //check a date
  if(!preg_match("/([0-9]+)([./-])([0-9]+)(\2)([0-9]+)/", $date, $m)) return false;
  $f = explode("/", $format);
  $d[$f[0]] = $m[1];
  $d[$f[1]] = $m[3];
  $d[$f[2]] = $m[5];
  return checkdate($d['mm'], $d['dd'], $d['yyyy'].$d['yy']);
}

function check_url($url){ //check a url
  return (bool) preg_match("/^(?:(?:ht|f)tp(?:s?)://|~/|/)?(?:(?:w+.)+)w+(?::d+)?(?:(?:/[^/?#]+)+)?/?(?:?[^?]*)?(#.*)?$/i", $url);
}
}

//调用方法

代码如下	复制代码
$validation = new validation(); //检测邮箱 var_dump($validation->check_email("abc@abc.abc.com"));//true var_dump($validation->check_email("abc.abc@abc.com"));//false

//ip检测

代码如下	复制代码
var_dump($validation->check_ip("127.0.0.1.0")); var_dump($validation->check_ip("256.0.0.1"));

//日期格式检测

代码如下	复制代码
//true var_dump($validation->check_date("2010/1/20", "yyyy/mm/dd")); var_dump($validation->check_date("1/20/10", "mm/dd/yy")); var_dump($validation->check_date("2010-20-1", "yyyy/dd/mm")); //false var_dump($validation->check_date("2010/2/29", "yyyy/mm/dd")); var_dump($validation->check_date("2010/1/20", "yyyy/dd/mm")); var_dump($validation->check_date("2010-20/1", "yyyy/dd/mm"));
