PHP实现密保卡功能实现代码,脚本之家提供下载可以直接运行的~!不需要数据库也不需要其他的,下载解压直接放环境中就可以看到效果

效果图:

密保卡入库

 
$this->load->model('admin/m_mibao'); 
$data = array(); 
//生成随机横坐标 
$rand_str = $this->_rand_str(10); 
$arr = array(); 
for($k=0;$k<strlen($rand_str);$k++) 
{ 
for ($i = 1;$i < 9;$i++) 
{ 
$rand = $this->_rand_num(3); 
//赋给所有code的容器 
$arr[$rand_str{$k} . $i] = $rand; 
} 
} 
$data['code'] = serialize($arr); //序列化后将信息入库 
$data['letter'] = $rand_str; 
//避免重复序列号 
while (TRUE) 
{ 
$data['card_num'] = $this->_rand_num(20); 
//判断序列号是否重复存在 
if($this->m_mibao->has_card_num($data['card_num']) == 0) 
{ 
break; 
} 
} 
$data['add_time'] = TIME; 
$data['user_id'] = $uid; 
echo $this->mibao->insert($data); 

密保卡图片生成

 
//就是算坐标 
public function show($user_id) 
{ 
$this->load->model('admin/m_mibao'); 
$info = $this->m_mibao->get_by_uid($user_id); 
if(emptyempty($info)) 
{ 
$this->msg('该用户无密保卡!','admin-index'); 
} 
$codes = unserialize($info['code']); 
//图片初始值 
$bit = 3; //密保卡位数 
$height = 332; //图片高度 
$width = 626; //图片宽度 
$im = imagecreatetruecolor($width,$height); 
$linecolor = imagecolorallocate($im, 229,229,229); 
$fontcolor = imagecolorallocate($im, 0, 0, 0); 
$top_rectangle_color = imagecolorallocate($im,241,254,237); 
$top_letter_color = imagecolorallocate($im,54,126,76); 
$left_rectangle_color = imagecolorallocate($im,243,247,255); 
$left_num_color = imagecolorallocate($im,4,68,192); 
$logo_str_color = imagecolorallocate($im,0,0,0); 
imagefill($im,0,0,imagecolorallocate($im,255,255,255)); //图片背景色 
$font = './public/baomi/fonts/simsun.ttc'; //字体 
$font_en = './public/baomi/fonts/CONSOLA.TTF'; //英文字体 
$font2 = './public/baomi/fonts/simhei.ttf'; //密保卡上方黑体 
$dst = imagecreatefromjpeg("./public/baomi/120.jpg"); 
imagecopymerge($im,$dst,120,15,0,0,193,55,100); 
imageline($im,10,72,$width-10,72,$linecolor); 
$ltext = "电子密保卡"; 
if(!imagettftext($im,10,0,340,47,$logo_str_color,$font2,$ltext)) { 
exit('error'); 
} 
//写入卡号 
$b = '1000' . $info['card_num']; 
for($i=0;$i<7;$i++){ 
$p.= substr($b,3*$i,4). ' '; 
} 
$x = 40; $y = 95; //序列号位置 
imagettftext($im,10,0,$x,$y,$color,$font,'序列号'); 
imagettftext($im,11,0,$x+50,$y,$color,$font_en,$p); 
//颜色框 
imagefilledrectangle($im,10,106,$width-10,128,$top_rectangle_color); 
imagefilledrectangle($im,10,129,65,$height-10,$left_rectangle_color); 
//写入最上排英文字母及竖线 
for($i=1;$i<=10;$i++){ 
$x = $i*55+35; $y = 123; $float_size = 11; //字母位置参数 
imagettftext($im,$float_size,0,$x,$y,$top_letter_color,$font_en,$info['letter']{$i-1});//写入最上排英文字母 
} 
for($i=0;$i<=9;$i++){ 
$linex = $i*55+65; $liney = 105; $liney2 = $height-10; //竖线位置参数 
imageline($im,$linex,$liney,$linex,$liney2,$linecolor);//划入竖线 
} 
//写入竖排数字及填入矩阵数据 划横线 
for($j=0;$j<8;$j++){ 
$jj=$j+1; 
$x=35; $y=($jj*24)+123; //左排数字及横线位置参数 
imagettftext($im, $float_size, 0, $x, $y, $left_num_color, $font_en, $jj);//写入左排数字 
for($i=1;$i<=10;$i++){ 
$float_size2=11; $x = $i*55+27; $sy=$y; //填入矩阵数据位置参数 
$s = $info['letter']{$i-1}; 
$s .= $j + 1; 
imagettftext($im,$float_size2,0,$x,$sy,$fontcolor,$font_en,$codes[$s]);//写入矩阵数据 
} 
} 
for($j=0;$j<10;$j++){ 
$line_x=10; $line_x2=$width-10;$y=$j*24+105; //横线位置参数 y坐标数据同上 
imageline($im,$line_x,$y,$line_x2,$y,$linecolor);//划入横线 
} 
//外框边线 
imageline($im,10,10,$width-10,10,$linecolor);//横线 
//imageline($im,10,$height-10,$width-10,$height-10,$linecolor); 
imageline($im,10,10,10,$height-10,$linecolor);//竖线 
imageline($im,$width-10,10,$width-10,$height-10,$linecolor); 
//生成图片 
ob_clean(); 
header("Content-type: image/jpeg"); 
imagejpeg($im,null,100); 
imagedestroy($im); 
} 

密保卡验证

 
public function test1($uid) 
{ 
$this->load->model('admin/m_users'); 
$user = $this->m_users->sel($uid); 
//post提交过来验证 
if($this->is_post()) 
{ 
$codes = $this->m_mibao->get_codes_by_uid($uid); 
$codes = unserialize($codes); 
$is_true = true; 
foreach($_SESSION['mibao']['keys'] as $key) 
{ 
if($codes[$key] != $_POST['values'][$key]) 
{ 
$is_true = false; 
} 
} 
if($is_true) 
{ 
die('正确'); 
} 
else 
{ 
die('错误'); 
} 
} 
else 
{ 
//渲染视图 
$info = $this->m_mibao->get_by_uid($uid); 
$data = array(); 
$data['keys'] = $this->m_mibao->get_rand_keys($info['letter']); 
$_SESSION['mibao']['keys'] = $data['keys']; 
$data['uid'] = $uid; 
$this->load->view('test1',$data); 
}
