PHP获取访客信息并合成图片

最近，闲的没事干，看到Rain在做这个项目，于是我也想坐一个争取比Rain好(不服)[Rain此项目链接:网页链接]

首先我们要用到的是1个API:IP归属地查询API(总不能自建IP库吧)

我们要用到的有:1.底图一张2.文字(ttf文字)

放写好的源代码：

<?php
//屏蔽错误提示(可以删掉)
error_reporting(E_ALL^E_NOTICE^E_WARNING);
//尝试多头部IP地址查询
function get_real_ip(){  
    static $realip;  
    if(isset($_SERVER)){  
        if(isset($_SERVER['HTTP_X_FORWARDED_FOR'])){  
            $realip=$_SERVER['HTTP_X_FORWARDED_FOR'];  
        }else if(isset($_SERVER['HTTP_CLIENT_IP'])){  
            $realip=$_SERVER['HTTP_CLIENT_IP'];  
        }else{  
            $realip=$_SERVER['REMOTE_ADDR'];  
        }  
    }else{  
        if(getenv('HTTP_X_FORWARDED_FOR')){  
            $realip=getenv('HTTP_X_FORWARDED_FOR');  
        }else if(getenv('HTTP_CLIENT_IP')){  
            $realip=getenv('HTTP_CLIENT_IP');  
        }else{  
            $realip=getenv('REMOTE_ADDR');  
        }  
    }  
    return $realip;  
}  
 
//获取City
function getCity($ip)
{
    $ch = curl_init();
    $url = 'https://whois.pconline.com.cn/ipJson.jsp?ip='.$ip;
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt ( $ch, CURLOPT_SSL_VERIFYPEER, false );
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    $location = curl_exec($ch);
    curl_close($ch);
    $location = mb_convert_encoding($location, 'utf-8','GB2312');
    $location = substr($location, strlen('({')+strpos($location, '({'),(strlen($location) - strpos($location, '})'))*(-1));
    $location = str_replace('"',"",str_replace(":","=",str_replace(",","&",$location)));
    parse_str($location,$ip_location);
    return $ip_location['addr'];
}
 
//获取系统
$_SERVER['HTTP_USER_AGENT'];
$_SERVER['HTTP_ACCEPT_LANGUAGE'];
function get_os() {
    if (!empty($_SERVER&['HTTP_USER_AGENT'])) {
        $os = $_SERVER&['HTTP_USER_AGENT'];
        if (preg_match('/win/i', $os)) {
            $os = 'Windows';
        } else if (preg_match('/mac/i', $os)) {
            $os = 'MAC';
        } else if (preg_match('/linux/i', $os)) {
            $os = 'Linux';
        } else if (preg_match('/unix/i', $os)) {
            $os = 'Unix';
        } else if (preg_match('/bsd/i', $os)) {
            $os = 'BSD';
        } else {
            $os = 'Other';
        }
        return $os;
    } else {
        return '未知';
    }
}
 
$redis = new Redis();    
$redis->connect('127.0.0.1', 6379);     
$check = $redis->exists("count");  
if($check){  
  $redis->incr("count");   
  $count = $redis->get("count"); 
    }

 
//获取浏览器
function browse_info() {
    if (!empty($_SERVER['HTTP_USER_AGENT'])) {
        $br = $_SERVER['HTTP_USER_AGENT'];
        if (preg_match('/MSIE/i', $br)) {
            $br = 'MSIE';
        } else if (preg_match('/Firefox/i', $br)) {
            $br = 'Firefox';
        } else if (preg_match('/Chrome/i', $br)) {
            $br = 'Chrome';
        } else if (preg_match('/Safari/i', $br)) {
            $br = 'Safari';

        } else {
            $br = 'Other';
        }
        return $br;
    } else {
        return 'unknow';
    }
}
 
//获取运营商
function getIsp($ip)
{
    $url="http://ip.taobao.com/service/getIpInfo.php?ip=".$ip;
    $ipinfo=json_decode(file_get_contents($url)); 
    if($ipinfo->code=='1'){
        return false;
    }
    $isp = $ipinfo->data->isp;
    return $isp; 
}
 
//打开图片
$dst_path = 'yuantu.png';//原图，修改为你原图的路径
$dst = imagecreatefromstring(file_get_contents($dst_path));
$font = './XXX.ttf';//字体路径
//获取刚才生成的数据
$browse= browse_info();
$ip= get_real_ip();
$isp= getIsp($ip);
$city=getCity("$ip");
$os=get_os();
$count0="$count 次";
//设定字体颜色
$black = imagecolorallocate($dst, 0x00, 0x00, 0x00);//字体颜色
//添加字体
imagefttext($dst,28,0,122,50,$black,$font,$ip);
imagefttext($dst,26,0,151,102,$black,$font,$city);
imagefttext($dst,28,0,155,153,$black,$font,$os);
imagefttext($dst,28,0,181,205,$black,$font,$isp);
imagefttext($dst,28,0,182,255,$black,$font,$browse);
imagefttext($dst,28,0,182,302,$black,$font,$count0);
//输出图片
list($dst_w, $dst_h, $dst_type) = getimagesize($dst_path);
        header('Content-Type: image/png');
        imagepng($dst);
imagedestroy($dst);
?>

注意，本程序需要Redis支持(如果你的主机不支持Redis，请尝试删除或修改Redis部分)
