< 4) ? "" : substr($phone, 0, 3); //邮箱前缀 $count = 0; $str = preg_replace('/([\d\w+_-]{0,100})@/', '***@', $phone, -1, $count); $rs = $prevfix . $str; return $rs; } else { //隐藏联系方式中间4位 $Istelephone = preg_match('/(0[0-9]{2,3}[\-]?[2-9][0-9]{6,7}[\-]?[0-9]?)/i', $phone); //固定电话 if ($Istelephone) { 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[0-9]{1}[0-9])[0-9]{4}([0-9]{4})/i', '$1****$2', $phone); } } } /** * 2、使用hidtel */ public function useHidel() { $phone1 = $this->

Hidtel ("010-57033050"); $phone2 = $this- > hidtel ("01057033050"); $mobil = $this- > hidtel ("13661226666"); $email = $this- > hidtel ("1963632356@qq.com"); return $phone1.''.$phone2.''.$mobil.''.$email;}
