PHP定时跳转

发布时间:2016-11-25 17:35

用PHP实现"等待指定的时间,然后再跳转到指定页面".
也就是用php实现和HTML中的
一样的效果。

<?
/**
@title:PHP定时跳转
@功能:等待指定的时间,然后再跳转到指定页面(代替html meta方式)
*/
header("refresh:3;url=http://www.etoow.com");

print('正在加载,请稍等...<br>三秒后自动跳转~~~');


/*
补充说明:
若等待时间为0,则与header("location:")等效。
*/

?>

首先写ActiveX Dll:
新建一个VB6工程,ActiveX Dll将工程命名为P_test,类名为c_test ,类的文件内容如下:

Option Explicit
Private MyscriptingContext As scriptingContext
Private MyApplication As Application
Private MyRequest As Request Private MyResponse As Response
Private MyServer As Server
Private MySession As Session Public

Sub OnStartPage(PassedscriptingContext As scriptingContext)
Set MyscriptingContext = PassedscriptingContext
Set MyApplication = MyscriptingContext.Application
Set MyRequest = MyscriptingContext.Request
Set MyResponse = MyscriptingContext.Response
Set MyServer = MyscriptingContext.Server
Set MySession = MyscriptingContext.Session
End Sub

Public Sub OnEndPage()
Set MyscriptingContext = Nothing
Set MyApplication = Nothing
Set MyRequest = Nothing
Set MyResponse = Nothing
Set MyServer = Nothing
Set MySession = Nothing
End Sub

Public Function Test_Number(num) As Variant
If num 0 Then Get_Number_Attrib = 1
If num = 0 Then Get_Number_Attrib = 0
End Function

编译生成p_test.dll文件

注册

提示符下运行:regsvr32 p_test.dll

编写php文件,test.php4代码如下:

<?php
$b=new COM("p_test.c_test");
$a=$b->Test_Number(-454);
echo $a;
?>

可能碰到的问题是,编译工程时通不过,要将Microsoft Active Server Pages Object Library引用进来,具体实现"Project->References"找到改库,并勾上 。

虚拟主机设置
<VirtualHost 127.0.10.10>
ServerAdmin webmaster@hostmachine.com
DocumentRoot /www/virtual.com/htdocs
ServerName www.virtual.com
UserDir /www/virtual.com/htdocs
ScriptAlias /cgi-bin/ /www/virtual.com/cgi-bin/
ErrorLog /www/virtual.com/logs/error_log
CustomLog /www/virtual.com/logs/access_log common

目录设置
<Directory /www/virtual.com/htdocs>
# 对该虚拟主机设置是否使用php3
php3_engine On
# 设置php3出错信息的调试级别
php3_error_reporting 1
# 设置是否记录php3出错日志
php3_log_errors On
# 设置php3的出错日志文件
php3_error_log /www/virtual.com/logs/php3_error_log
# 设置一个php3线程的最长存活时间
php3_max_execution_time 180
# 设置用户临时上载目录
php3_upload_tmp_dir /www/virtual.com/htdocs/tmp
# 设置包含头文件
php3_include_path /www/virtual.com/htdocs/include

可执行目录设置

Options Indexes FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all

$ftp_server = "*.*.*.*";
$ftp_user = "lu";
$ftp_pass = "love you";

// set up a connection or die
$conn_id = ftp_connect($ftp_server) or die("Couldn't connect to $ftp_server");

$login_result = ftp_login($conn_id, $ftp_user, $ftp_pass);

if ((!$conn_id) || (!$login_result)) {
echo "FTP connection has failed!";
echo "Attempted to connect to $ftp_server for user $ftp_user_name";
exit;
} else {
echo "Connected to $ftp_server, for user $ftp_user_name";
}

// try to login
$filename=date('Ymd').".xml";
$source_file="/usr/local/IVR/sendwireless/xml/data/".$filename; //源地址
echo $source_file;
$destination_file="/ITC/admin/logstat/ftplog/".$filename; //目标地址
$upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY) or die("Couldn't connect to $ftp_server");
ftp_quit($conn_id);

if (!$upload) {
echo "FTP upload has failed!";
} else {
echo "Uploaded $source_file to $ftp_server as $destination_file";
}
ftp_close($conn_id);

最近一段时间对PHP文件处理方面很感爱好,因此在许多站点上看了许多的文件处理的文章,但是国内许多的站点上的PHP文件处理方面的知识大多数是你抄我的我抄你的,用baidu.com或者是google.com搜索出来的东西多是重复的。最近在国外一个站点上盾了一篇文章感觉很不错,因此推荐给大家阅读。

首先我们有必要说明一下文件上传的操作流程及用到的知识点:

文件上传我们需要用到HTML里面表单的type="file"类型,及其enctype属性。这是我们大家必须要用的。当然了PHP函数库当中的FILE函数库,字符串类型函数库,目录函数库及$_FILES[]的使用是我们必须要用到的。

也许每一个站点都可能会对上传文件有许多的限制,这些限制会包括 文件类型,文件大小,扩展名,以及上传目录的存在与否,上传文件的存在与否,目录的可写性,可读性,上传文件的改名及怎样把文件从缓存当中复制到你所需要的目录当中。

当然出错的预处理也是我们不容忽视的!假如再深一步的讨论我们还可以对文件的操作起用事件日志的记录。

下面我们通过一段程序来实现这些功能:

--------------------------------------------------------------------------------------------


首先是我们预设的变量值,它包括文件大小,文件扩展名类型,MIMI类型,及是否删除的开关变量

$MAX_SIZE = 2000000;
$FILE_MIMES = array('image/jpeg','image/jpg','image/gif'
,'image/png','application/msword');

$FILE_EXTS = array('.zip','.jpg','.png','.gif');

$DELETABLE = true;


下一部就是设置浏览器访问变量及目录访问变量:

$site_name = $_SERVER['HTTP_HOST'];
$url_dir = "http://".$_SERVER['HTTP_HOST'].dirname($_SERVER['PHP_SELF']);
$url_this = "http://".$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'];

$upload_dir = "files/";
$upload_url = $url_dir."/files/";
$message ="";


建立上传目录并相应改变权限:

if (!is_dir("files")) {
if (!mkdir($upload_dir))
die ("upload_files directory doesn't exist and creation failed");
if (!chmod($upload_dir,0755))
die ("change permission to 755 failed.");
}



用户请求的处理:

if ($_REQUEST[del] && $DELETABLE) {
$resource = fopen("log.txt","a");
fwrite($resource,date("Ymd h:i:s")."DELETE - $_SERVER[REMOTE_ADDR]"."$_REQUEST[del]n");
fclose($resource);

if (strpos($_REQUEST[del],"/.")>0); //possible hacking
else if (strpos($_REQUEST[del],"files/") === false); //possible hacking
else if (substr($_REQUEST[del],0,6)=="files/") {
unlink($_REQUEST[del]);
print "<script>window.location.href='$url_this?message=deleted successfully'</script>";
}
}
else if ($_FILES['userfile']) {
$resource = fopen("log.txt","a");
fwrite($resource,date("Ymd h:i:s")."UPLOAD - $_SERVER[REMOTE_ADDR]"
.$_FILES['userfile']['name']." "
.$_FILES['userfile']['type']."n");
fclose($resource);

$file_type = $_FILES['userfile']['type'];
$file_name = $_FILES['userfile']['name'];
$file_ext = strtolower(substr($file_name,strrpos($file_name,".")));
