一个简单的图形计数器

需要MYSQL，GD的支持，LINUX下PHP4RC1通过，这也是我做的系统中正在用的。<?php/***hit_count表只一个字段hit_countpage_visit_record表是用来控制一个IP一天内只产生一个计数器跳动CREATE TABLE page_visit_record (;;;visit_time datetime DEFAULT '0000-00-00 00:00:00' NOT NULL,;;;remote_addr char(15) NOT NULL,;;;visit_page char(60) NOT NULL,;;;KEY visit_time (visit_time, visit_page),;;;PRIMARY KEY (visit_time));***/include("config.inc.php3");$query="select count(*) as tong from page_visit_record where remote_addr='$REMOTE_ADDR' and date_format(visit_time,'%Y-%m-%d')=curdate()";$result=@mysql_query($query,$dbconnect);$has_count=@mysql_result($result,0,"tong");@mysql_query("lock tables hit_count write",$dbconnect);$query="select * from hit_count";$result=@mysql_query($query,$dbconnect);if(@mysql_num_rows($result)>0){;;;;$cur_count=@mysql_result($result,0,"hit_count");;;;;if($has_count==0){$cur_count++;$query="update hit_count set hit_count='$cur_count'";@mysql_query($query,$dbconnect);;;;;};;;;@mysql_query("unlock tables",$dbconnect);}else{;;;;$cur_count=1;;;;;$query="insert into hit_count (hit_count) values ('$cur_count')";;;;;@mysql_query($query,$dbconnect);;;;;@mysql_query("unlock tables",$dbconnect);}while(strlen($cur_count)<8);;;;$cur_count="0$cur_count";$visit_time=date("Y-m-d H:i:s");$query="insert into page_visit_record (visit_time,remote_addr,visit_page) values ('$visit_time','$REMOTE_ADDR','$page')";@mysql_query($query,$dbconnect);Header("Content-type: image/gif");$im = imagecreate(56,16);$black = ImageColorAllocate($im, 0,0,0);$blue = ImageColorAllocate($im, 0,0,255);$white = ImageColorAllocate($im, 255,255,255);$yellow = ImageColorAllocate($im, 255,255,0);imagerectangle($im, 0, 0, 54, 14, $blue);//imagestring($im, 2, 4, 1, $cur_count, $yellow);imagestring($im, 2, 4, 1, $cur_count, $yellow);ImageGif($im);ImageDestroy($im);?>
