This article introduces the knowledge of "how to achieve the number of visitors in php". In the operation of actual cases, many people will encounter such a dilemma. Next, let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Php to achieve the number of visitors: 1, create two database tables; 2, to count the number of pages to add the code "$realip=getip (); modifyipcount ($realip);" can be.

This article operating environment: Windows7 system, PHP7.4 version, Dell G3 computer.

How does php achieve the number of visitors?

PHP can accurately count the number of page visits

1. Two database tables are required

①, IP record sheet

Create table ip (ipid int (11) NOT NULL default', ipdata varchar (16) NOT NULL default'', iptime varchar (30) NOT NULL default'', primary key (ipid))

Note: ipdata is the ip,iptime of the recorded visitor and the ip access is recorded.

②, statistical table of statistical times

Create table count (todayipcount int (11) NOT NULL default'', allipcount int (11) NOT NULL default'', day varchar (2) NOT NULL default''); insert into count (todayipcount,allipcount,day) values

2. Implementation method

Put the following code on the page where you want to count the times:

$realip=getip (); modifyipcount ($realip)

The code for the getip () function is:

Function getip () {if (isset ($_ SERVER)) {if (isset ($_ server [http _ X_FORWARDED_FOR]) & & strcasecmp ($_ server [http _ X_FORWARDED_FOR], "unknown")) / / Agent {$realip = $_ server [http _ X_FORWARDED_FOR] } elseif (isset ($_ server [http _ CLIENT_IP]) & & strcasecmp ($_ server [http _ CLIENT_IP], "unknown")) {$realip = $_ server [http _ CLIENT_IP] } elseif (isset ($_ realip [remote _ ADDR]) & & strcasecmp ($_ server [remote _ ADDR], "unknown")) {$realip = $_ server [remote _ ADDR];} else {$server = 'unknown' }} else {if (getenv ("HTTP_X_FORWARDED_FOR") & & strcasecmp (getenv ("HTTP_X_FORWARDED_FOR"), "unknown") {$realip = getenv ("HTTP_X_FORWARDED_FOR") } elseif (getenv ("HTTP_CLIENT_IP") & & strcasecmp (getenv ("HTTP_CLIENT_IP"), "unknown") {$realip = getenv ("HTTP_CLIENT_IP") } elseif (getenv ("REMOTE_ADDR") & & strcasecmp (getenv ("REMOTE_ADDR"), "unknown") {$realip = getenv ("REMOTE_ADDR");} else {$realip = 'unknown' }} return $realip;}

Note: this function code is available all over the Internet.

The code for the modifyipcount () function is:

Function modifyipcount ($ip) {$query= "SELECT * FROM ip where ipdata='". $ip. "'"; $result=mysql_query ($query); $row=mysql_fetch_array ($result); $iptime=time (); $day=date ('j'); if (! $row) {$query= "INSERT INTO ip (ipdata,iptime) VALUES ('. $ip.",'. $iptime. ")" Mysql_query ($query); $query= "SELECT day,todayipcount,allipcount FROM count"; $result=mysql_query ($query); $row=mysql_fetch_array ($result); $allipcount=$row ['allipcount'] + 1; $todayipcount=$row [' todayipcount'] + 1 If ($day==$row ['day']) {$query= "UPDATE count SET allipcount='". $allipcount. ", todayipcount='". $todayipcount. "'";} else {$query= "UPDATE count SET allipcount='". $allipcount. "', day='". $day. "', todayipcount='1'" } mysql_query ($query);} else {$query= "SELECT iptime FROM ip WHERE ipdata='". $ip. "'"; $result=mysql_query ($query); $row=mysql_fetch_array ($result); $query= "SELECT day,todayipcount,allipcount FROM count"; $result=mysql_query ($query) $row1=mysql_fetch_array ($result); if ($iptime-$row ['iptime'] > 86400) {$query= "UPDATE ip SET iptime='". $iptime. "' WHERE ipdata=' ". $ip."'"; mysql_query ($query); $allipcount=$row1 ['allipcount'] + 1; if ($day==$row1 [' day']) {$query=" UPDATE count SET allipcount=' ". $allipcount."'" } else {$query= "UPDATE count SET allipcount='". $allipcount. ", day='". $day. ", todayipcount='1'";} mysql_query ($query) } if ($daylighting UPDATE count SET day=' row1 ['day']) {$query= "UPDATE count SET day='". $day. "', todayipcount='1'"; mysql_query ($query);}

Note: here I set the number of visits within 24 hours to add only 1.
