独家专供:PHP的URL验证正则算法,有史以来最强悍的

经过多年的积累,逐步完善写出的url验证算法

function isUrl($s)
{
	return preg_match('/^http[s]?:\/\/'.
		'(([0-9]{1,3}\.){3}[0-9]{1,3}'. // IP形式的URL- 199.194.52.184
		'|'. // 允许IP和DOMAIN(域名)
		'([0-9a-z_!~*\'()-]+\.)*'. // 三级域验证- www.
		'([0-9a-z][0-9a-z-]{0,61})?[0-9a-z]\.'. // 二级域验证
		'[a-z]{2,6})'.  // 顶级域验证.com or .museum
		'(:[0-9]{1,4})?'.  // 端口- :80
		'((\/\?)|'.  // 如果含有文件对文件部分进行校验
		'(\/[0-9a-zA-Z_!~\*\'\(\)\.;\?:@&=\+\$,%#-\/]*)?)$/',
		$s) == 1;
}

要是还遇到问题,请把有问题的url贴上来,希望还能继续完善
