本篇文章主要介绍了PHP手机号中间四位用星号*代替显示的实例,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

在显示用户列表的场景中,一般用到手机号的显示时都需要对手机号进行处理,一般是把中间的四位换成星号****,我本人用php处理的思路是进行替换,用****替换手机号的中间四位

代码如下:

$all_lottery_logs = ********;     //该语句是得到中奖纪录
//遍历处理手机号
foreach($all_lottery_logs as $k=>$v){
   $xing = substr($v['tel'],3,4);  //获取手机号中间四位
   $all_lottery_logs[$k]['tel'] = str_replace($xing,'****',$v['tel']);  //用****进行替换
}
Copy after login

另外几种方法

<?php
$tel = &#39;12345678910&#39;;
//1.字符串截取法
$new_tel1 = substr($tel, 0, 3).&#39;****&#39;.substr($tel, 7);
var_dump($new_tel1);
//2.替换字符串的子串
$new_tel2 = substr_replace($tel, &#39;****&#39;, 3, 4);
var_dump($new_tel2);
//3.用正则
$new_tel3 = preg_replace(&#39;/(\d{3})\d{4}(\d{4})/&#39;, &#39;$1****$2&#39;, $tel);
var_dump($new_tel3);
?>
Copy after login

结果:

> string(11) "123****8910"
> string(11) "123****8910"
> string(11) "123****8910"
Copy after login

以上就是本文的全部内容,希望对大家的学习有所帮助。
