PHP - Page Requests From Parsed Php Pages

Hi all

I have a question about how to store parsed data into a multidimensional arrays -- I can store items into an array, but multidimensional arrays mystify me a bit.  Any help would be greatly appreciated. 

I'm storing the images in a table, grouped according to their table and their descriptions, so that later when I call the images, I can display them accordingly. I'm using the Simple HTML DOM Parser.  So say I have two tables, one with three images, and another with one.  I'd like the resulting to array to look like:

Code: [Select]
Array
(
    [0] => Array
        (
            [0] => image1.jpg
            [1] => 1st Variation Description
        )

    [1] => Array
        (
            [0] => image2.jpg
            [1] => image3.jpg
            [2] => image4.jpg
            [3] => 2nd Variation Description
        )

)

This is what I have so far:
Code: [Select]
$html = str_get_html($vartables);   
$varinfo = array();
foreach($html->find('table') as $table){
        $varinfo[] = $table->innertext;
}
print_r($varinfo);

Which yields:

Code: [Select]
Array
(
    [0] =>
 <tr>
  <td width=150>
Description1
 </td>

 <td><a href="image1.jpg">
<img src="image1" height=100 border=1></a>
  </td>
 </tr>

    [1] =>
 <tr>
  <td width=150>
Description2
  </td>

<td><a href="image2.jpg">
<img src="image2.jpg" height=200 border=1></a>
  </td>
  <td><a href="image3.jpg">
<img src="image3.jpg" height=200 border=1></a>

  </td>
 <td><a href="image4.jpg">
<img src="image4.jpg" height=200 border=1></a>
  </td>
 </tr>

)

I'd like to strip out the html and keep the .jpg's and descriptions together in a multidimensional array...unfortunately my newbness is getting the better of me there, I'm researching but running into a roadblock.  Thanks in advance for any help.

I'm a new PHP users needing some help. I've got two code snippets that run a CURL post to a syslog server grabbing specific records that I then parse with regex. Both are similar differing in the specific CURL URL and Regex. One works does not. The failing program seems to fail the regex parse creating a null array. What I've done thus far. Tested the regex on regex101 (works fine, using PCRE). Dumped and echoed the CURL created variable and then rechecked against regex101. ( again all good) Created a static variable in the code of the CURL return string (regex works fine). 

So the CURL is working, the variable string is working appearing as expected and the regex works. But the variable feels like's it null when passed directly from the CURL to the regex. No error logs, but this is where I'm stuck I don't know what to pick at next.  Here's a version of the code. Appreciate any thoughts.

I was just wondering if when I write a new function that uses AJAX should I use the same http request for my whole website or should I make seperate ones for each function?  Also if you use the same one do you need to do anything to it once it has been used to set the ready status back to 0?

Thanks

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.

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?

How can I track session requests, so I can, after a certain number of requests (let's say ten because it's physcologically pleasing), have the id regenerated?

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?

this is my code which is using to check login from database calledchklogin.php

Code: [Select]
<?php
session_start();
include('connect.php');

$tbl_name="members"; 

mysql_select_db($Db, $link); 


// username and password sent from form
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];

// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
$mypassword = md5($mypassword);

$sql="SELECT * FROM $tbl_name WHERE uname='$myusername' and upass='$mypassword'";
$result=mysql_query($sql,$link);
$row=mysql_fetch_array($result);
                                
// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row

if($count==1){
// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("username"); //Create the session
session_register("myusername");
session_register("mypassword");
$_SESSION['uname'] = "$myusername";
$_SESSION['utype'] = $row['utype'];

header("location:loginsuccess.php"); 
}
else {
//include ('index.php');
echo ("<script type='text/javascript'> window.alert('Wrong username or password!')</script>");
exit();
}

?>
& this code is from another file called loginsuccess.php

Code: [Select]
<?
session_start();
if(!session_is_registered(myusername)){
header("location:index.php");
exit();
}
require_once("login-index.php");           
?>


so when everything is right in chklogin.php then it open loginsuccess.php after that when all is true then it open
login-index.php after that this page open it show double page one is index.php where the login form & another is this login-index.php at one time

Hello, I'm new here and need some help.
I'm a beginner with PHP

Here's what I have....

The index page looks like this:

<? include("header.php"); ?>
<? include("sidebar.php"); ?>
<? include("main.php"); ?>
<? include("footer.php"); ?>

On all of the pages for the site, the only thing that will change will be:  <? include("main.php"); ?>
When viewing the home page, the title in the browser shows:  Home Page (which is what I want).
However, when clicking on links in the nav bar, I want the title to reflect those page names.

For example, the code above displays the home page, but then if you click on (for example) "Bio's" in the navigation bar, it will take you to the Bio's page, obviously.   the link for that menu item is:   bio.php.

The bio.php page looks like this:

<? include("header.php"); ?>
<? include("sidebar.php"); ?>

<div> All the data and formatting for this page </div>

<? include("footer.php"); ?>

.............

I would like to put some php code in the header that will automatically detect the title of each page, how can I do this?

Should I put <? title=Bio's Page ?> (or whatever page) at the top of each page, then call to it somehow from the header?

Any help would be appreciated.

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

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?

Hi guys so i want to make page acces to certain ranks.

So im thinking for something like this

    rank1 -> home.php, admins.php
    rank2 -> home.php
    rank3 -> home.php
    rank4 -> home.php

So the ranks are in a database with the page names. So now when someone logs in they will get a certain rank. So now i need to make a function that will check if the rank has access to this page.

$curPageName = substr($_SERVER["SCRIPT_NAME"],strrpos($_SERVER["SCRIPT_NAME"],"/")+1);

This will detect the current page that the logged in person is at now. But now how do i check if the $_SESSION['rank']; (rank1) has the access to get in page admins.php, and obviously to make $_SESSION['rank'];(rank2) redirect from the page admins.php

Could someone point me in the right direction? Do i select the ranks and page names from database then put it into a array?

Thanks.

Hi everyone,

I have this script that identify's the current page in the navigation

Code: [Select]
<?php $currentPage = basename($_SERVER['SCRIPT_NAME']); ?>
<ul id="nav"><!-- Open Nav -->
    <li><a href="index2.php" <?php if ($currentPage == 'index2.php') {echo 'class="selected"';} ?>>Home</a></li>
    <li><a href="salon-information.php" <?php if ($currentPage == 'salon-information.php') {echo 'class="selected"';} ?>>Salon Information</a></li>
    <li><a href="about-us.php" <?php if ($currentPage == 'about-us.php') {echo 'class="selected"';} ?>>About us</a></li>
    <li><a href="hair-care-advice.php" <?php if ($currentPage == 'hair-care-advice.php') {echo 'class="selected"';} ?>>Hair Care Advice</a></li>
</ul><!-- Close Nav -->


My problem is that hair-care-advice.php has a number of sub pages. How do I get it so the selected class remains selected for all the sub pages as well as the main page.

Any help would be greatly appreciated

Thank you

Barry
