PHP基础函数库(补充中)

function get_member_tel($id = 0) {
    $data = module('common')->model->table('member')->field('tel')->where('uid=' . $id)->find();
    $res = substr_replace($data['tel'], '****', 3, 4);
    return $res;
}

function is_url($v){
 $pattern="#(http|https)://(.*\.)?.*\..*#i";
 if(preg_match($pattern,$v)){ 
  return true; 
 }else{ 
  return false; 
 } 
}
