Requirements from a working colleague, the implementation of a PHP file IP filtering, not convenient to configure the server directly, so need to directly at the beginning of the php file for IP filtering.
IP filtering rules can have the following forms:
1. Complete IP address such as: 192.168.0.1
2. A section of

Below I collect several commonly used shielding IP list of program processing method, shielding this can make your website better, more stable, below we do not analyze the following shielding method.
$ip _str = "127.0.0.1,192.1.1.*,202.*,127.*,123.*,142.*,*";$ip = "127.0.0.254";function Stopip ($
corresponding to the distribution of precise control routes, IP prefix-list has a good application.
