PHP实现手机号码中间四位用星号(*)隐藏的自定义函数分享

php屏蔽电话号码中间四位:

Method 1function hidtel($phone){
     $IsWhat = preg_match('/(0[0-9]{2,3}[\-]?[2-9][0-9]{6,7}[\-]?[0-9]?)/i',$phone); //固定电话
    if($IsWhat == 1){
         return preg_replace('/(0[0-9]{2,3}[\-]?[2-9])[0-9]{3,4}([0-9]{3}[\-]?[0-9]?)/i','$1****$2',$phone);
     }else{
         return  preg_replace('/(1[358]{1}[0-9])[0-9]{4}([0-9]{4})/i','$1****$2',$phone);
     }
 }

Method 2$num = "13966778888"
 $str = substr_replace($num,'****',3,4);

 

示例:

$phonenum = "13966778888";
echo hidtel($phonenum);

 

 

最后输出:139****8888
