查询系统

前几天做了个大学英语四六级成绩查询系统，一个 phprpc 版本，一个 wap 版本。它们的核心代码都是相同的。下面就是从 etang.cet 获取大学英语四六级成绩的核心代码：

下载: cetquery.php

function query($examid, $examtype) {
$examid = trim($examid);
$examtype = trim($examtype);
if (!is_numeric($examid)) {
return '准考证号码必须是数字';
}
if (strlen($examid) != 15) {
return '准考证号码不正确';
}
if ($examtype == '1') {
if ((substr($examid, 6, 4) != '0521') &&
(substr($examid, 6, 4) != '1052')) {
return '准考证号码与考试类型不符';
}
}
if ($examtype == '2') {
if ((substr($examid, 6, 4) != '0512') &&
(substr($examid, 6, 4) != '0522') &&
(substr($examid, 6, 4) != '2052')) {
return '准考证号码与考试类型不符';
}
}
$examid1 = substr($examid, 0, 6) . $examtype . '052' . substr($examid, 10, 5);
$request = "examtype=$examtype&examid=$examid&image.x=23&image.y=32";
$content_len = strlen($request);
$handle = @fsockopen('cet.etang.com', 80, $errno, $errstr, 10);
$buf = '';
$id = base_convert(mt_rand().mt_rand(), 10, 36);
if ($handle) {
$http_request =
"POST /dog/cet HTTP/1.0/r/n" .
"Accept: */*/r/n" .
"Referer: http://cet.etang.com/cet_girldemand_$id.htm/r/n" .

$request;
fputs($handle, $http_request, strlen($http_request));
while (!feof($handle)) {
$buf .= fgets($handle, 128);
}
fclose($handle);
}
else {
return "查询服务器暂时无法连接";
}
$buf = explode("/r/n", $buf);
$buf = $buf[11];
$score = "";
if (substr($buf, 0, 18) == 'Set-Cookie: score=') {
$score = substr($buf, 18, strpos($buf, ';') - 18);
}
if (($score != '') and ($score != 'error')) {
$score = explode(',', $score);
}
else {
return '你所查询的准考证号码不存在';
}
return $score;
}
