我的第一个PHP程序（by quqi99)

由于有个工作任务要用到php，以前没接触过这玩意，现学现卖，学习了半天，折腾了半天，有了下列程序。程序中通过curl调用两个java servlet完成用户的注册，批VIP。由于要求用户注册后保持登录状态，也将servlet返给php脚本的cookie再通过设置cookie返给客户端。代码如下：

regUser.php文件：

<?php
$regUseUrl = 'http://zhanghua/LiteRegistration';
$approveVipUrl = 'http://zhanghua/JsonTools';
$livetoolUser = '';
$livetoolPass = '';
$logDir = '/home/site/data/lk';
$logFile = 'regUser.log';

function curl($url, $user, $pw, $field, $ispost = 1) {
$ch = curl_init();
if($ispost == 1){
curl_setopt($ch, CURLOPT_POSTFIELDS, $field);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
}else{
curl_setopt($ch, CURLOPT_URL, $url."?".$field);
}
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt ($curl, CURLOPT_HTTPHEADER, $header);
if($user && $pw){
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD,"$user:$pw");
}
$http = curl_exec($ch);
if (curl_errno($ch)){
echo "Error: " . curl_error($ch);
}
curl_close($ch);

// forward cookie
$response = preg_split ("/\r\n\r\n/", $http, 2);
$headers = preg_split ("/\r\n/", $response[0]);
for ($i = 0; $i < count ($headers); $i++) {
$header = explode (":", $headers[$i]);
switch ($header[0]) {
case "Set-Cookie":
header ($headers[$i], FALSE);
break;
default:
break;
}
}
return $response[1];
}

function writeLog($dir,$file,$msg){
if (!file_exists($dir)) {
mkdir($dir,0777,TRUE);
}
$logFile = $dir.'/'.$file;
$msg = date('Y-m-d H:i:s').' >>> '.$msg."\r\n";
if(file_put_contents($logFile,$msg,FILE_APPEND) == FALSE){
echo "Can not write ".$logFile;
chmod ($dir, 0777);
}
}


// judge verify code
session_start();
$verifyCodeSession = $_SESSION["check_num"];
unset($_SESSION['check_num']);

$verifyCode = $_POST["verifyCode"];
$verifyCodeMD5 = md5($verifyCode);
if(empty($verifyCodeSession) || $verifyCodeMD5 != $verifyCodeSession){
$arr = array(
'reason'=>'verify code is invalid',
'success'=>false
);
$json_string = json_encode($arr);
echo $json_string;
return;
}
// reg user by invoking LiteRegistration
extract($_POST);
$fields = array(
'litereg_travelFor'=>$litereg_travelFor,
'litereg_gender'=>$litereg_gender,
'litereg_keepSignedIn'=>$litereg_keepSignedIn,
'litereg_pass'=>$litereg_pass,
'litereg_locationId'=>$litereg_locationId,
'litereg_location'=>$litereg_location,
'litereg_travelFrequency'=>$litereg_travelFrequency,
'litereg_email'=>$litereg_email,
'litereg_username'=>$litereg_username,
'litereg_travelStyle'=>$litereg_travelStyle,
'litereg_DOB'=>$litereg_DOB
);
$fields_string = "form-name=litereg&".http_build_query($fields);
// {"username":"quqi","memberid":"149137","reason":"ok","success":true,"displayname":"quqi"}
$jsonResult = curl($regUseUrl,'','',$fields_string,1);
$objResult = json_decode($jsonResult,true);
// log it
$msg = "RegUser: ".$litereg_username.'@'.$litereg_pass.'_'.$_SERVER["REMOTE_ADDR"].' '.$jsonResult;
echo $msg;
writeLog($logDir, $logFile, $msg);
if($objResult["success"]==true){
// approve VIP
$memberid=$objResult["memberid"];
$params = array(
'action'=>'approveVip',
'memberid'=>$memberid
);
$params_string = http_build_query($params);
$approveVipJsonResult = curl($approveVipUrl,$livetoolUser,$livetoolPass,$params_string,0);
$msg2 = "ApproveVip: ".$memberid." ".$approveVipJsonResult;
writeLog($logDir, $logFile, $msg2);
$approveVipObjResult = json_decode($approveVipJsonResult,true);
}
?>

chkCode.php如下：

<?php
Header("Content-type: image/PNG");
session_start();
srand((double)microtime()*1000000);
$im=imagecreate(45,18);
$black=imagecolorallocate($im,0,0,0);
$white=imagecolorallocate($im,255,255,255);
$gray=imagecolorallocate($im,200,200,200);
imagefill($im,0,0,$gray);
session_register("check_num");
$_SESSION["check_num"]="";
$authnum = '';
for($i=0;$i<4;$i++){
$str=mt_rand(1,3);
$size=mt_rand(3,6);
$onebit = mt_rand(0,9);
$authnum.=$onebit;
imagestring($im,$size,(5+$i*10),$str,$onebit,imagecolorallocate($im,rand(0,130),rand(0,130),rand(0,130)));
}
$_SESSION["check_num"]=md5($authnum);
for($i=0;$i<150;$i++){
$randcolor=imagecolorallocate($im,rand(0,255),rand(0,255),rand(0,255));
imagesetpixel($im,rand()%70,rand()%30,$randcolor);
}
imagepng($im);
imagedestroy($im);
?>
