正则表达式编写与收集

1. 匹配url地址

$reg = "/^(https?:\/\/)?(\w+\.)?(\w+\.)(\w+)(:\d+)?(\/\w+)*\/?(\?\w+=[^\s=&]+(&\w+=[^\s=&]+)*)?(#\w)?$/i";
$str = 'https://asdfewiiw.dsfsd.com:12323/user/index/?name="李四"&age=20&next=21#name';
// $str = 'https://dsfsd.com:12323/user/index/?name="李四"&age=20&next=21#name';
// $str = 'dsfsd.com:12323/user/index?name="李四"&age=20&next=21#name';
// $str = 'dsfsd.com/user/index?name="李四"&age=20&next=21#name';
// $str = 'dsfsd.com?name="李四"&age=20&next=21#name';
// $str = 'dsfsd.com?name="李四';
// $str = 'dsfsd.com';
$p = preg_match($reg, $str, $match);
var_dump($match);

 2. 匹配手机号

$reg = "/^1[3-9]\\d{9}$/";
$str = '13923222322';
$p = preg_match($reg, $str, $match);
var_dump($match);

 3. 匹配邮箱

$reg = "/^\w+@\w+\.\w{1,3}$/";
$str = 'jiarenmen@okle.com';
$p = preg_match($reg, $str, $match);
var_dump($match);
