Example of replacing asterisks in the middle of php mobile phone number

Today, the editor will introduce to you how to use the preg_replace function to replace the specified numbers in the middle of the mobile phone number with asterisks. This is used on many websites. Everyone will do this, let me introduce the example method below.

Regular expression method

1. The string contains multiple mobile phone numbers

The code is as follows

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})#', '***', $s); echo $s; //王经理：139*365 李经理：135***741 ?>

Copy code

代码如下	复制代码
$haoma="15012345678"; echo preg_replace("/(d{3})d{5}/","***",$haoma); //150***678 ?>

$s='Manager Wang: 13999312365 Manager Li: 13588958741';
$s=preg_replace('#(d{3})d{5}(d{3})#', '${1}*****${2}', $s);

echo $s;

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

//Manager Wang: 139*****365 Manager Li: 135*****741

代码如下	复制代码
echo substr($string1,0,3)."***".substr($string1,8,3); //132***555 ?>

2. There is only one mobile phone number in the string

The code is as follows

Copy code

$haoma="15012345678"; echo preg_replace("/(d{3})d{5}/","$1*****",$haoma); //150*****678 ?> Achieved without regular expressions 1. Use substr_replace string partial replacement function

The code is as follows

Copy code

$string1="13264309555"; <🎜> echo substr_replace($string1,'*****',3,5); <🎜> //132*****555 <🎜> ?> 2. Use the string interception function substr
