PHP - Oop, Includes And Requires Are Causing Extra Requests Aren't They?

Hello!

I'm trying to understand exactly how http requests relate to a php script. 

1)  What would be considered a large amount?
2)  How can I see how many I have for a given page?

Thank you,

Eric

I think it's fsockopen that enables you to do web requests right?? I was wondering if you could also make it use a proxy instead of your website's IP. Would that be possible?

Hi,

I am trying to make a web interface for a robot, I have written php to send/recieve values via a serial port to my robot. They work.

I am now tring to develop my web interface.

I'm using java to generate http requests client side in the form of;
Code: [Select]
/request?command=Forward&param1=254
I was wondering how I can parse the command and param1 in php sereverside?

Or is there a better alternative?

Hello there everyone. I'll try to explain as thorough as I can so please bare with me a bit. One you want to surf the web through a proxy in firefox, you go to tools > options > network > settings and enter proxy details which for example are like this. 173.123.123.4 and port 8080. I want to do pretty much the same thing with php for my visitors.

I have www.site1.com which will have all my scripts and stuff. I want it to somehow redirect or load to www.site2.com USING A PROXY so that when the visitor reach site2, it's as if they have edited their firefox settings to view site2 using a proxy. That way visitors will always be anonymous on www.site2.com. While searching, I found this:

http://stackoverflow.com/questions/3889715/php-requests-through-proxy

Which seems simple enough but does not work unfortunately. Not that I'm even sure that it's indeed what I want to do but it seems like it...lol.

Thanks a lot for any help provided.

I have script on my web hosts server built into pages that will be offered to the public, eg: index.php will have some script amongst the html, this script calls other webpages on the net eg: wiki.org

Now my question is, when that script runs when somebody accesses that page, will the website eg: wiki.org record the users browser info and ip who called my index page or will it record the webhosts server details as the one making the requests?

I created an app for my website, set action (read) and object (article), and placed the objects code (META tags in the head) at the article page on my website.

Now, I want to know how to send a cUrl request whenever a user reads an article on my website, so it'll feature on his wall.

When I press the "get code" link near the action, that's what I get:

Code: [Select]
curl -F 'access_token=***' \
 -F 'article=http://example.com' \
    'https://graph.facebook.com/me/yellowheart:read'

(There's an actual access token of course).

Now, how do I make it happen?

Purpose: Building a search function for a site, that's supposed to be fast, give results as a user types.

Queries would be something like: "brand1 brand2 brand3" .

My idea is , instead of querying the database on each ajax request. A keyed array is created once. Like: ['brand1' => id , 'brand2 => id2 ]. This array is stored in memory. The next time a query is sent, the array which is instantly available in memory, and can be simply queried $storedArray['brand1']to fetch any existing ids instantly. The array size would be about 750 Kb. 60000 rows.

I don't have much experience with caching , so looking for advise whether what I am trying to do even makes any sense or necessary. I know there are solutions like memcache. But not sure if my tiny project requires them. Also does opcache help here ? Would serializing the array be too slow ? 

Please ask if any questions.

Thanks

I have an object which is very expensive to create, and is fairly large but by no means enormous.  The object has two tasks:

Display to the user what can be changed in a database. Make some or all of those changes based on user input.

Instead of creating it first to perform the first task, I would like to serialize it and store it somewhere and then restore it to perform the second task to reduce user wait time.  Communication of both tasks is as follows where the web client first makes a XMLHttpRequest and then cURL is used for the remaining:

Web Client -> Web Server -> REST API Server -> Time Historian Application (and then back in the same order)

In addition, both of these tasks take significantly longer than 30 seconds resulting in cURL error 28.  I certainly can investigate to determine which of the requests are causing this error, however, feel that the solution to persisting the object might solve this issue as well.

I am thinking of making the REST API server responsible for temporarily storing the object, and am considering the following:

Web client makes XMLHttpRequest to web server and passes session cookie. Web server makes cURL request to REST API server and passes that same cookie (maybe a bad idea?). REST API server initiates the time historian application, spawns some new process, and replies to the web server maybe with some expected wait time duration, and web server in turn responds to web client. Spanned process when object is complete serializes the object's content and saves it as JSON using the session cookie as the filename. Web client periodically makes requests to web server which in turn make requests to REST API server and when the JSON file is available, recreates the object, executes the applicable method, and replies with the applicable content. Web client sends user data to the web server and in turn to the REST server to initiate the second task. Web client similarly periodically makes requests to web server which in turn make requests to REST API server to check if complete and if so the JSON object file is deleted. If request has not been fulfilled within 24 hours or so, JSON object file is deleted.

I would appreciate any general feedback or recommendations how best to accomplish this, and whether using some 3rd party framework such as Gearman, ReactPHP, redis, etc might simplify matters.

Thank you

It's been a while since I've needed to whip anything substantial up from scratch, so my scripting is a little (lot) fast and loose (weird/inefficient) here.

I'm trying to mock up a script that's essentially a quiz/survey. There are a handful of topics, each with a few screens of yes/no questions. At the end, it returns a list of recommendations based on the answers gathered.

The script is posting back to itself. Using print_r ($_SESSION), it seems like all of the post values for the first screen of questions are being assigned to the session array as expected. When the second screen of questions is answered, their values are assigned as well, but the values for the first set go away completely. This continues through subsequent screens, with the values from the previous screen present and all others before missing.

I'd really appreciate a look at my code to see if you tell me the cause or error(s).

Thanks!

Here are the two if statements:

   if (!($start <= 0)){
   
   $prev_button = "<a href='forum.php?category_id=$category_id&start=$prev'>Prev</a>";
   
   }
   
   if (!($start >= $record_num - $per_page)){
   
   $next_button = "<a href='forum.php?category_id=$category_id&start=$next'>Next</a>";
   
   }

But they are not properly working. This is part of a pagination script for the next and previous buttons.

Hey guys,

Really dumb question, but I want to check if a bunch of variables are all not empty. Then, if they aren't, I want to execute a mySQL query. Right now I have this which I know is wrong because it doesn't work the right way:

Code: [Select]
if($album != null || $artist != null || $year != null || $genre != null) {
// stuff here...
}

Obviously I want all of those variables to be checked if they are empty or not. I did a quick Google and found that checking if the variables are null wouldn't be the correct way of solving this situation because an "empty string" is still not null?

Anyway, any help would be appreciated. I'm pretty sure it's really simple :p.

Hi

I have a table (applicant) that has a number of fields but included a
applicantid
party1
party2
party3
party4
party5

Any number of these party entries could have data in them but I need to know, for any specific applicantid, the count of how many non null entries there are.

I can't find a way to do it.

Does anyone have any ideas.

Many thanks

I wish to have a page that will display a form if there aren't already enough registrations in the database. The following it an outline of how it will be:

<?php
require_once "../scripts/connect_to_mysql.php";                        //this works fine


// Count how many records in the database
(1) $sqlCommand = "SELECT * FROM teams"; 
(2) $sqlCommand = "SELECT COUNT (*) FROM teams";
(3) $sqlCommand = "SELECT COUNT (id) FROM teams";
$query = mysqli_query($myConnection, $sqlCommand) or die (mysqli_error());
(1) $numRegistrations = mysql_num_rows($query); //Count how many rows are returned from the query above
(2) $numRegistrations = $query
(3) $numRegistrations = mysql_num_rows($query);

mysqli_free_result($query);
?>
(Some HTML code, like DOCTYPE, head, start of body tags)
<?php
if($numRegistrations > 35){
echo "Sorry, registrations for this event is at it's maximum.";
}else{
?>

<form blah blah blah>

</form>

<?php
}
?>

(end of body and html tag)



You'll see above there is (1), (2), (3). These are the main 3 that I've been trying, and they match up the $sqlCommand to the $numRegistrations.

What would be the problem with this code? I use wamp server to test, have been using it for ages. Chrome browser to test in.
If I remove the database query, the rest of the page will load.
With the query in there, only the HTML code up until the database query is parsed, so therefore nothing is display on the page.

Please help.

Thanks
Denno

Sorry for the long message but I need HELP!!!  I'm somewhat familiar with HTML but very little in PHP, and even less in CSS. My eCommerce program is PHP based so I've had to learn to work with it. I did have someone else initially setup and create my website but over the past few years have taken it further myself. I've fiddled with some of it and looked up how to do certain things, such as have only one header and/or sidebar I can use for all pages. I use Dreamweaver CS4 and FTP with FileZilla. But I'm still new at this and have run into a couple of issues.   My webhost is GoDaddy, my website is MikiCat Designs and after fiddling for months, in March finally got my site to where I liked it. Unfortunately, I haven't kept it up. Anyway, I went there a couple of weeks ago and found that the PHP includes I'd had in the HTML files were no longer working. I get the error [an error occurred while processing this directive]. Weird. Worked fine before, now it doesn't. Called GoDaddy who says they didn't do anything . Uh huh. Now I know I didn't do anything since I haven't updated the site in 4 months! So, what could have caused this problem?

I've had no idea how to fix it other than to change the index.html to index.php and, of course, do a minor repair on the include. Works fine and my header.php and leftsidebar.php show up again. Yay! Herein lies another problem.

My header and sidebar link to other files some of which were HTML files. But those HTML files had the same header and sidebar issues as my INDEX file. This had to be fixed so I changed them to PHP. Still working on the changes. I deleted most of the HTML files from the server.

So the links in my header and lefsidebar files now point to PHP files. e.g., gallery.html to gallery.php. When called on it's own, gallery.php shows up perfectly. But, no matter what I do, the header file still tries to load the HTML file!!! It's driving me crazy. What have I done wrong? I've deleted them both, refreshed, cleared cache and uploaded them again but I still get the same error. If you click on Gallery in the header, it tries to link gallery.html not gallery.php! Funny thing is, the leftsidebar now works perfectly and points to the proper PHP files. I'm completely confused now.

I don't know why my header is insisting on trying to load the HTML page instead of the PHP. But here's my header code. Lines 41 and 42 work, lines 43, 44 and 45 do not.   * Quietly banging head against wall while awaiting help.

Hey people!

I'm currently working on an free API that i will be sharing with the web community in the next few months and had a question that much of this project hinges upon:

Is there a way to allow a remote include of one php file from my server?

Case:
I am allowing 2 ways for users to access the APi:

1. Using AJAX or cURL accessing a REST method over POST or GET (This part is already functional)
2. Allowing an include of the API Library
    I'm not sure if it will be completely opensource yet, only free, this is why I don't want to simply provide the source files to users.

Example of what I would like to do:

<?php
include('http://mysite.com/myAPI/classLib.php');
?>


Anybody have a solution for that??


Thanks in advance,

E
