PHP - How To Use Variables From Other Included Files

Hello. Trying to learn MVC better by creating my own little framework to understand how it works.

Things were going OK til now.

I have a base class:

<?php

/**
 * Base class most classes will extend from.
 * Simply put, this class just has methods that
 * most, if not all, classes will need.
 */

class Application {

public function includer($path) {

if (is_readable($path) == true) {
include_once($path);
} else {
die("404 not found =[");
}
}




}
?>


So the above method 'includer' just sees if a file exists/is readable and if so, include it.

Here's where I am using said method.


class Index extends Application {

function __construct($method = 'view') {
// load the index model
include(ROOT . '/app/models/model.index.php');

// Invoke requested method.
$this->$method();
}

public function view() {

$name = 'Smith';
$this->includer(ROOT . '/app/views/view.index.php'); # Problem here, i think
}


}


view.index.php just contains
<?php echo $name; ?>


All that is called from the index page, with this line of code
Application::includer($controller_path);


Now, in line
$this->includer(ROOT . '/app/views/view.index.php'); # Problem here, i think

If i get rid of $this->includer, the script will work and say 'Smith'.

If i have $this->includer(...) or parent::includer(...), it doesn't work.

why?

Hi Guys,
               I am relatively new to php, and have hit a problem.  Basically I am writing a PHP socket server - which acts as a socket server for a swish movie.  The only way of getting data into the swish movie is one function - loadvariablesnum() - which uses 'post' or 'get'.  The swish movie is a web GUI for a system and therefore needs a reasonably decent refresh rate - 5 times a second for example.  Originally I wrote a php file that created / bound / listened to the socket and then entered an infinite while loop that would read from the socket and echo the output to the swish movie.

The problem with this method, was that each time the swish movie called loadvariablesnum() the PHP script would re-open - re-bind - re-listen to the socket - which caused all sorts of problems for my client.  Therefore I decided to re-write the PHP file that included functions:

Code: [Select]
<?               //TCP_Socket_Server.php
global $output;

function TCP_Socket_Server()
{
$host = "10.10.13.59";
$port = 10000;
set_time_limit(0);
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");
$result = socket_bind($socket, $host, $port);// or die("Could not bind to socket\n");
$result = socket_listen($socket, 3) or die("Could not set up socket listener\n");
socket_set_block($socket);
$spawn = socket_accept($socket) or die("Could not accept incoming connection\n");
// read client input
while(1)
{
$input = socket_read($spawn, 10000);// or die("Could not read input\n");
$input = trim($input);
global $output;
$output = $input;
WriteData();
flush();
}
socket_close($spawn);
socket_close($socket);
}

function WriteData()
{
static $LocalTemp;
global $output;
$LocalTemp = $output;
$TempBuffer = "&TCP_SocketServerBufferVar=";
//$TempBuffer .= $GLOBALS['output'];
$TempBuffer .= $LocalTemp;
echo $TempBuffer;
}
?>
Using this method I can call TCP_Socket_Server() only once at the beginning of the swish movie using the loadvariablesnum() (from another PHP file), which sets the server running - e.g.

Code: [Select]
<?    //Load_Server.php
include 'TCP_Socket_Server.php';
TCP_Socket_Server();
?>
My plan was to then call the WriteData() function regularly approximately 5x per second, (again from another PHP file using loadvariablesnum() in swish):

Code: [Select]
<?    //Write_Data.php
include 'TCP_Socket_Server.php';
Write_Data();
?>
However, when I call this function from an external PHP file - no valid data is output by echo - even though I can see the data being received (in the browser) in the main Load_Server.php page - which is output using the same Write_Data() function.
I have tried many different ways of accessing this variable ($output) from a different php file - e.g returning the variable from Write_Data() - which had the same result (i.e. no valid data).

I have also tried using sessions, but could only seem to get them to work in files that did not run indefinitely - e.g. without the infinite while loop in TCP_Socket_Server().

I am currently running the PHP files (and the rest of the web content) on APACHE2 - in Ubuntu.

I would really appreciate any advice on this - as at the moment, this looks like a show stopper - and would waste 2 months work.

Hi,

i'm new to php and am trying to call $variables in different in multiple hierarchy from one main variable file.

I have one main file called variables.php that contain a list of variables
<?php
$variable1 = 'root/main/';
$variable2 = 'welcome';
$variable3 = 'testing';
?>

a second file called file1.php in the same directory as the variables.php file
<?php
require 'varibles.php';
include $variable1 . 'testing.php'
?>

a third file called testing.php inside root/main/
<?php
echo $variable2;
include $varible1 . 'temp/abc.php';
?>

a fourth file called abc.php inside root/main/temp
<?php
echo $variable3;
?>

the problem is testing.php is able to echo $variable2 but abc.php is not able to echo $variable3...is there a limit to the level of files before it can't echo a variable?

Hi,

I'm having a bit of a problem sharing some variables I have across a few files.

My first file (index.php) calls an ajax request for (display.php) and sends a few variables to it. All fine so far. display.php then does its thing and displays the content on index.php as it should. Now in display.php I need a variable to be passed back to index.php for use in a menu.
I've tried setting a session variable in display.php but unfortunately this doesn't seem to work. I also can't use get or post as I don't want to refresh the page.

Really scratching my head over this one!

I hope that subject made sense!

I have a page where I want to generate page-specific keywords automatically. Actually I have some general keywords stored in a text file and then I add the page-specific ones after those. The problem is, however, solely caused by the keywords I pull from my text file. A "1" is added to my list of keywords. Consider a news page like so:

news.php
// ...
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta name="keywords" content="<?php require('php/generateKeywordList.php'); ?>" />
</head>
// ...

And then generateKeywordList.php
// I have omitted the part with the page-specific keywords, because it is not what causes the problem (commented it all out)
set_include_path('/mypath/');
$str = require_once('includes/websiteKeywords.txt');
echo $str; // For some reason, the number 1 is added at the end of this string


websiteKeywords.txt (it doesn't matter what I put in there)
Code: [Select]
these, are, my, keywords, for, my, website
In my meta tag, the above would be displayed as:
Code: [Select]
these, are, my, keywords, for, my, website1
I then tried to make a simple php page like this

$keywords = require('includes/websiteKeywords.txt');
echo $keywords;

... and it worked. At the moment I have absolutely no idea where the number 1 comes from.

So, basically if I include the keywords directly from the text file into my meta tag, it displays fine. If I make a simple php page where I echo out the keywords from the text file, it displays fine. But if I include my php script, which echos the keywords, into my meta tag, the number 1 is added at the end of the string.

Am I completely missing something here or is this extremely strange?


Thanks for any help!

I understand that this is a header error but i still do not know how to fix it.
I am trying to create a login box that is in the top right corner of my site. Once the user uses it to log in they need to be redirected to the account page. i include the login_box.php file in the appropriate div. however the file uses header("Location: account.php"); to redirect the user. because this file is included after the header i receive Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\index.php:17) in C:\xampp\htdocs\layout_inc\login_box.php on line 76
What would be the correct way to do this. My code is bellow. Thank you in advance

Hi,

$user_id = '22';

now when i go over to the somescript.php i write at the top that print $user_id; and i get nothing.

What am i doing wrong?

Hello


I have a simple question about file handling...


Is it possible to list all files in directories / subdirectories, and then read ALL files in those dirs,
and put the content of their file into an array?

Like this:

array:
[SomePath/test.php] = "All In this php file is being read by a new smart function!";
[SomePath/Weird/hello.txt = "Hello world. This is me and im just trying to get some help!";

and so on, until no further files exists in that rootdir.

All my attempts went totally crazy and none of them works... therefore i need to ask you for help.


Do you have any ideas how to do this?
If so, how can I be able to do it?


Thanks in Advance, pros

So far I have managed to create an upload process which uploads a picture, updates the database on file location and then tries to upload the db a 2nd time to update the Thumbnails file location (i tried updating the thumbnails location in one go and for some reason this causes failure)

But the main problem is that it doesn't upload some files

Here is my upload.php

<?php
include 'dbconnect.php';

$statusMsg = '';

$Title = $conn -> real_escape_string($_POST['Title']) ; 
$BodyText = $conn -> real_escape_string($_POST['ThreadBody']) ; 
	 

// File upload path
$targetDir = "upload/";
$fileName = basename($_FILES["file"]["name"]);
$targetFilePath = $targetDir . $fileName;
$fileType = pathinfo($targetFilePath,PATHINFO_EXTENSION);
$Thumbnail = "upload/Thumbnails/'$fileName'";

if(isset($_POST["submit"]) && !empty($_FILES["file"]["name"])){
    // Allow certain file formats
    $allowTypes = array('jpg','png','jpeg','gif','pdf', "webm", "mp4");
    if(in_array($fileType, $allowTypes)){

        // Upload file to server
        if(move_uploaded_file($_FILES["file"]["tmp_name"], $targetFilePath)){

            // Insert image file name into database
            $insert = $conn->query("INSERT into Threads (Title, ThreadBody, filename) VALUES ('$Title', '$BodyText', '$fileName')");
            if($insert){
               $statusMsg = "The file ".$fileName. " has been uploaded successfully."; 

		$targetFilePathArg = escapeshellarg($targetFilePath);
		$output=null;
		$retval=null;
		 //exec("convert $targetFilePathArg -resize 300x200 ./upload/Thumbnails/'$fileName'", $output, $retval);
		 exec("convert $targetFilePathArg -resize 200x200 $Thumbnail", $output, $retval);
		echo "REturned with status $retval and output:\n" ; 
		if ($retval == null) { 
		echo "Retval is null\n" ;
		echo "Thumbnail equals $Thumbnail\n" ; 
		}

            }else{
                $statusMsg = "File upload failed, please try again.";
            } 
        }else{
            $statusMsg = "Sorry, there was an error uploading your file.";
        }
    }else{
        $statusMsg = 'Sorry, only JPG, JPEG, PNG, GIF, mp4, webm & PDF files are allowed to upload.';
    }
}else{
    $statusMsg = 'Please select a file to upload.';
}

//Update SQL db by setting the thumbnail column to equal $Thumbnail
$update = $conn->query("update Threads set thumbnail = '$Thumbnail' where filename = '$fileName'");
            if($update){
               $statusMsg = "Updated the thumbnail to sql correctly.";
		echo $statusMsg ;  } 
else 
{ echo "\n Failed to update Thumbnail. Thumbnail equals $Thumbnail" ; } 


// Display status message
echo $statusMsg;
?>

And this does work on most files however it is not working on a 9.9mb png file  which is named "test.png" I tested on another 3.3 mb gif file and that failed too?

For some reason it returns the following

Updated the thumbnail to sql correctly.Updated the thumbnail to sql correctly.

Whereas on the files it works on it returns

REturned with status 0 and output: Retval is null Thumbnail equals upload/Thumbnails/'rainbow-trh-stache.gif' Failed to update Thumbnail. Thumbnail equals upload/Thumbnails/'rainbow-trh-stache.gif'The file rainbow-trh-stache.gif has been uploaded successfully.

Any idea on why this is?

Hey!

I have a small code where I want to check if one variable matches the other when the other is sent through a function. The function, for practical reasons, is included with a separate PHP-file. And I cant seem to apply a variable to the function which processes the other variable. Its really wierd to me.

Here is the code for the main PHP-file:

Code: [Select]
<?php

include 'function.php';

$unformatted = "FORMATTING AY ...";

$formatted1 = "formattingay...";

$formatted2 = test_format($unformatted);

if ($formatted1 == $formatted2) {
     echo "Success, formatted!";
} else {
     echo "Fail, unformatted.";
}

?>
And here is the code for "function.php":

Code: [Select]
<?php

function test_format($var) {
     strtolower(str_replace(array(" "), array(""), $var));
}

?>
Does anybody have a clue to why this simply wont work? Any answers and help is highly appreciated!

I have created a script (single file) that works fine when testing it alone, but when included it doesn't and rest of page is blank.

What could cause this? Is this because of some "mismatch" between the queries, variables used on the included file and the existing file?

Say I have...

Code: [Select]
<?
echo("do something");
include("include_file.php");
echo("do something else");
?>

include_file.php
Code: [Select]
<?
$a_$string = "a string";
echo($a_string);
?>

I have put an error in the include_file.php  an extra $ in the variable name.

The first script would kick up an error that there is a problem with file   include_file.php  as line 3 or what ever the line may be.

How can I have it so I can choose what the error message is, say a cryptic code and the line number without having the file names show as this is showing up my hidden includes folder and the file name which means that someone may try to visit this page alone and this can cause security issues.

Adding in extra lines to every file to see if it is being use correctly a bit like sessions is not an option although I have looked at it as I have houndreds of files to alter in this case.


I have just tried this instead of the top script but I does not show the secret code on error
Code: [Select]
<?
echo("top");
@include("dummy.php") or die("secreterrorcode123");
echo("bottom");
?>
