PHP - Stop The Client Waiting For Server.

i have php at server side and c++ at client side.what i am trying to do is to constantly look for files on server in folder on server if there’s a file in folder then download it on client side and delete it from server folder
this will happen again and again after 5minutes if a file is present on server in folder then download it and delete from server then in c++ goto sleep again fro 5 minutes and after 5 minutes do all this again if no file present in folder on server then simply do nothing.

Hi All - I'm trying to see if the below is possible using PHP.

is it possible for php to allow a user to check if a port is open/listening on a remote server/PC, from their local machine. I've seen scripts on the web that talk about opening cmd.exe - this won't work as not all of my users will be on windows. Also saw fsock.. but the remote server is not serving http page(s). Also saw telnet, but again, some of my users may not have that windows feature enabled.

Desired workflow:

1. user enters the server hostname/IP and a port

2. my php webapp will emulate checking if that hostname and port is open from the local user's computer.

 

thanks!

I have a web app that uses an API that I wrote to communicate with my MySQL database that was written in PHP. Currently, each user of the API is required to authenticate before using the API with a username/password. Every API request is logged into a Requests_History table which stores the API request type, the timestamp and the userId of the requester.

How can I easily stop hammering of the API via too many requests in a given time period?

1. first violation within 24 hours, 2 minute ban
2. second violation within 24 hours, 10 minute ban
3. second violation within 24 hours, 1 hour ban

I have a web portal which is scripted using client side scripting language i.e HTML. I want to create a login page in .php and want the other pages to be in .hmtl.
Can i do so?
I want to do this because i want the login password to be stored in a database. Also I want the password to get encrypted (by either MD5 javascript or OpenSSL ) when user enters it inside the login form.

I cannot create the entire portal in php because my portal makes use of C code. And php doesn't have an interface with C language.

Can a user get directed to a .html page after a secure login from login.php page ?
My main aim is to secure the access to my web portal using a password.

I tried to authenticate the login using javascript where the password was stored in an array. But i feel any one having moderate knowledge can easily break that password.

Any help would be greatly appreciated!!

Hi..,
I use below method to export data to excel.

header('Content-type: application/ms-excel');
header('Content-Disposition: attachment; filename=abc.xls');

if I run the script from the server. (http://localhost/export.php) it is work. (pop-up window if i want save or open the file)

but if i run the script from the client (http://192.168.1.5/export.php) it is not work. (nothing happen)

any idea how to solve this?

Anyone know how I can print a file (specifically a PDF) that is stored on the server to the clients computer with a button?  I don't want them to be able to view it, just print it.  I've done some research and understand that there is no way to print directly without popping up the Windows Print dialog.  And that is fine.  I just want them to print this file, but not no where it is or be able to type in a URL to access it.
Thanks
Mike

I have to some how get data from my sql data to a clients sql db server.  They suggested using xml which is great i can output the required fields as xml but how then do i push this so it goes into the clients sql db..

We cant just do a db insert this has been ruled out.

Im happy using xml just have no idea how to push it at a particular host / sql db any ideas or suggestions would be really welcome.. 

is it true that all the server side code runs before the client side code when accessing a webpage?  if that is true, what about PHP code that is embedded inside HTML tags?  wouldn't that result in an error a lot of times?

Haven't done much in PHP for a while, and as a refresher and a bit of a challenge to myself I have decided to write up a simple game of sorts.

Basically in the game I have townships, every play has their own town. And I want these towns to have events every 3-10 hours, and have these events have results such as births/deaths/fires/flooding/etc.

At the moment I'm looking at this kind of setup:
A database table with the city information.. city_id, city_owner_id, city_name, etc. I figure I can make another field such as city_nextevent and fill it with a timestamp plus a random number of seconds. then when the user views their city if city_nextevent is older than current time then run the event function and set the next event time.

In my head this idea seems to work well, until I realised that if the user doesn't log on for 20+ hours the events will not stack, they will only get the one event when they next view their town when several events should have passed. I realise I could use a cronjob to check all events across all towns, but is there a better way of doing it.

I had also though about adding several fields to the database containing say the next five event times, then updating each field after time had passed. Which gives more events if the user has been offline for 20+ hours. So if the play was offline for say a week, their town would pretty much dry up until they returned.

Basically, I want their town to run while they're offline. But was trying to avoid using a cronjob.

Anyone have any thoughts on how this could be done?

I am in the process of creating a waiting list that I want to work automatically. When a new member registers for membership, the member must be on a waiting list for a while before the member gets permanent membership. When the membership is activated by me, I want this to work like when I delete the person who is number 1 in the list, and number 2 will be number 1. the remaining numbers in the list will automatically move a number up, just now . 5 will be number 4 and so on. PErson number one is the person that allways will be deleted from the waiting list. An idea would be that this persons name ande rest of data connected to hes membership number will be moved automaticaly to the permanent members list when hi is deleted from the waiting list. Only the name will be displayed in the member list, but the form that the new member submits will have several fields. There are t12 fields to be filled in in the MySQL database, but only the name and surname to be displayed in the list. The numbers will be generated automatically in front of the name.

I have tried to do this by myself. I have tried to do this myself, but I do not succeed. I am very new when it comes to PHP and programming in general. Hope someone here can help me with this. I can not find out.

Hello all.
I have a php script which will insert csv data into database using PDO.
But it's slow even with just few thousands records.

So how can I prevent client from waiting for it when they want to upload data?

I tried INSERT DELAYED but it's not working...

Thank you.

Hi all,

    I have a tool currently in place that pulls information from one server and displays it. Currently in the setup, whenever the status of a chat has "Waiting". It's grouped with all other's as $num_waiting. The problem I am having is do to the server it pulls the information from, 1 session would equal 11 if there are 11 reps answering chats. The issue with divising by the number of active agents is on occasion the server reports more or less than the number of agents which in turn generates responses like 3.3333 and so on.  And no the number with that status has never actually equaled to a single instance.

As such you can see my dilemma here, I need to find a way of taking all sessions with that status and most likely cross-referencing another attribute such as $customername to prevent the doubles and finally provide only a single instance for each of these sessions. I am including the bulk of the current code below. Any help is much appreciated.

Code: [Select]
<?php
$num_waiting = 0;

foreach($loginParams as $login){
    $soapclient = new soapclient("https://secure.logmeinrescue.com/API/API.asmx?WSDL");

                    {

Hey guys.

I'll be doing a frontend for some router testing scripts and I'll need to launch some shell scripts in php. The user will be allowed to check some checkboxes - choose which tests to run and run them using a button. I want to show them some kind of "Testing in progress" string and then show them the result when it's done. What do you think is the best solution ?

I was thinking the shell script should create the whole output in some sensible form and then I would just parse it. Should I use a database for storing the error strings, or do you think they should be a part of the script ?

Also, I would like to do it with AJAX (I never did it before and I could use some experience). So I need some advice on this. I want the form to disappear after the button was pressed, replace it with the "testing in progress" string (or maybe a temporary popup window would be better) and then if the script is done, display the result. I guess I need to use the Code: [Select]
shell_exec command.
What would you suggest ?

btw I guess there is no way to run a script on a different server than one which runs the webpage, is there ?

I have a PHP web system that store in a windows server. In the system, there is a function for user to upload files to another server (Shared server in Unix).

When i try to upload a file, it gives warning:

Warning: move_uploaded_file(\\unixserver/sharedfolder/upload/test.txt) [function.move-uploaded-file]: failed to open stream: Permission denied in C:\wamp\www\upload\index.php on line 40

For your information, my username has been assigned in xxx's group that has access to read and write on that folder. Besides, i'm able to open,create and delete files on that folder's server manually (samba).

The safe mode setting is off.

Does anybody has any idea why this thing happen?
