今天小编来给各位同学介绍利用preg_replace函数把手机号码中间指定几伴替换成星号了，这个在很多网站 都会有这样做，下面我来介绍实例方法。


正则表达式方法

1、字符串中包含多个手机号码

 代码如下 复制代码

$s='王经理：13999312365 李经理：13588958741';
$s=preg_replace('#(d{3})d{5}(d{3})#', '${1}*****${2}', $s);
echo $s;
//王经理：139*****365 李经理：135*****741
?>

2、字符串中只有一个手机号码

 代码如下 复制代码

$haoma="15012345678";
echo preg_replace("/(d{3})d{5}/","$1*****",$haoma);
//150*****678
?>

不用正则表达式实现
1、使用substr_replace字符串部分替换函数

 代码如下 复制代码

$string1="13264309555";
echo substr_replace($string1,'*****',3,5);
//132*****555
?>

2、使用字符串截取函数substr

 代码如下 复制代码

echo substr($string1,0,3)."*****".substr($string1,8,3);
//132*****555
?>
