自己的一个验证电话和ecshop验证电话

//验证电话
function checkPhone($phone)
{
    $preg_mobile = preg_match("/^1\d{10}$/", $phone );
    $preg_phone_city = preg_match("/^0\d{2}-?\d{8}$/", $phone );
    $preg_phone_county = preg_match("/^0\d{3}-?\d{7}$/", $phone );
    $preg_phone_general = preg_match("/^\d{7,8}$/", $phone );
    if(($preg_mobile||$preg_phone_city||$preg_phone_county||$preg_phone_general))
    {
        return true;
    }
    return false;
}

ecshop电话验证

    if (!empty($office_phone) && !preg_match( '/^[\d|\_|\-|\s]+$/', $office_phone ) )
    {
        show_message($_LANG['passport_js']['office_phone_invalid']);
    }
    if (!empty($home_phone) && !preg_match( '/^[\d|\_|\-|\s]+$/', $home_phone) )
    {
         show_message($_LANG['passport_js']['home_phone_invalid']);
    }

一个ecshop后台ajax修改电话的例子

<td align="center"><span onclick="listTable.edit(this, 'edit_phone', {$entity.id})">{$entity.phone}</span></td>

/*------------------------------------------------------ */
//-- 修改客户电话号码
/*------------------------------------------------------ */
elseif ($_REQUEST['act'] == 'edit_phone')
{
    //check_authz_json('goods_manage');

    $user_id   = intval($_POST['id']);
    $phone  = $_POST['val'];

    if(!checkPhone($phone))
    {//电话有误
        make_json_error("手机格式不对");
    }
    $sql = "update c_users set phone='$phone' where id=$user_id";
    if($db->query($sql)){
        clear_cache_files();
        make_json_result($phone);
    }
}
