這里提供兩種關于Email正則表達式與URL正則表達式驗證的正則,非常的實用,關于email的正則表達式可以把內容中的所有郵箱地址獲取出來,而url地址正則也一樣,可以把內容中所有http開頭url地址保存提取來哦。
Email正則表達式:
- $str_arr = array(
- "mymail@phpfensi.com",
- "my_mail@phpfensi.com",
- "my-mail@phpfensi.com",
- "my.mail@site.com.cn",
- "mymail@site.com.com",
- "mymail@site.cn",
- "mymail@@@lsite.com",
- "mymail@site",
- "mymail@phpfensi.com",
- "my2007@phpfensi.com",
- "163mail_for-me777@phpfensi.com",
- );
- $patt_email = "/^[_a-za-z0-9-]+@([0-9a-z][0-9a-z-]+.)+[a-z]{2,4}$/";
- foreach ($str_arr as $str)
- {
- echo "字符串'$str'：是";
- if (preg_match($patt_email, $str))
- {
- echo "合法的email格式";
- echo "
"; - echo "
"; - }
- else
- {
- echo "不合法的email格式";
- echo "
"; - echo "
"; - }
- }
url正則表達式:
- $str_arr = array(
- "http://www.phpfensi.com",
- "www.phpfensi.com",
- "http://www.phpfensi.com/abc/123.html",
- "//phpfensi.com",
- ":www.phpfensi.com"
- );
- $patt_url = "/^(http://)?[a-za-z0-9]+(.[a-za-z0-9]+)*.+$/";
- foreach ($str_arr as $str)
- {
- echo "字符串'$str'：是";
- if (preg_match($patt_url, $str))
- {
- echo "合法的url格式";
- echo "
"; - echo "
"; - }
- else
- {
- echo "不合法的url格式";
- echo "

"; - }
- }
