分别匹配电话、手机、邮箱和网址的比较强大正则表达式

匹配全部URL地址和链接内容 代码如下:

$str = "<a href='http://www.baidu.com' target='_blank'>百度</a>http://www<a href='http://www.sina.com' target='_blank'>新浪</a>";

preg_match_all(" <a href=([\"\'])(http:\/\/([\w\d\.])+)[^>]*>(.*?)<\/a>",$str,$matches);

echo "<pre>";
var_dump($matches[2]);
echo "<br />";
var_dump($matches[4]);

匹配邮箱 代码如下:

$emails = "[e-mail][e-mail]";

preg_match_all("/ ([a-z0-9_\-\.]+)@(([a-z0-9]+[_\-]?)\.)+[a-z]{2,3}/i",$emails,$matches);

var_dump($matches[0]);

匹配手机以及电话号码 代码如下:

$tel = "13911112222sf010-44444442dfg18811112222";

preg_match_all("/ 1[3,5,8]{1}[0-9]{1}[0-9]{8}|0[0-9]{2,3}-[0-9]{7,8}(-[0-9]{1,4})?/",$tel,$matches);

var_dump($matches);

备注:如果是java中要用到正则表达式,需要注意转义字符.以匹配网址的正则表达式为例:String ReguPattern = "<a class=\"title\" target=\"_blank\" href=([\"\'])(http:\\/\\/([\\w\\d\\.])+)[^>]*>(.*?)</a>";
