PHP can only access the same IP once within the time limit

Create a data table

CREATE TABLE ' clicks ' (

' IP ' INT UNSIGNED not NULL,

' time1 ' INT UNSIGNED not NULL,

' Time2 ' INT UNSIGNED not NULL,

PRIMARY KEY (' IP ')

) ENGINE = MYISAM

Get IP and current time insert into datasheet

INSERT into clicks (ip,time2) VALUES (Inet_aton (' {$_server[' remote_addr "]} '), Unix_timestamp ()) on DUPLICATE KEY UPDATE Time1=time2, Time2=unix_timestamp ()

Validate on re-access

SELECT Inet_ntoa (IP) from clicks WHERE Ip=inet_aton (' {$_server[' remote_addr "]} ') and Time1+3600-time2+3600<=unix_ TIMESTAMP ();

Permission is allowed within the specified time, otherwise access is denied.
