Chinese汉语词条或短语: 为空则不限制
This phrase comes up quite a bit in my translation and it usually in this format:

推送服务的IP限制,为空则不限制;多个用逗号","隔开,如8.8.8.8,192.168.0.0/16

It also comes up like this as well:

允许登录IP,为空则不限制

Not entirely sure what it means. Any help would be appreciated.

English英语翻译:Leave blank to allow all
说明:
AFAIK this is usually phrased differently in English.

1. Restricted IP addresses for push services. Leave blank to allow all (IP addresses).
or even
Deny IP list for push services. Leave blank to allow all.

2. IP addresses allowed to access. Leave blank to allow all (IP addresses).

The following link may help you express this in English.

Jan 27, 2010 - 关于empty(). empty() 用于检查一个变量是否为空。如果变量是非空或非零的值,则empty() 返回FALSE。换句话说,""、0、"0"、NULL、FALSE、array()、var $var; 以及没有任何属性的对象都将被认为是空的,如果var 为空,则返回TRUE。 empty() 与isset() 的一个简单比较。 <?php $var = 0; // 结果为true,因为$var 为 ...
