I want to getting class by included url between two hosts , I had to called class , there is a point which i have to creating an API , like a library to calling whatever. or it must be do by another way ?!
call.php
<?php
class call{
public function Call_Name($c = "") {
$c = "Called";
return $c;
}
}
?>
index.php
<?php
include 'http://example.com/new/call.php';
$call = new call();
echo $call->Call_Name();
?>
(allow_url_fopen , allow_url_include) is already on.
What you are looking for just isn't safe.
Instead of attempting to execute remote code, consider using a package manager such as Composer/Packagist. You can write your general classes once as a "library" and share them among your "packages".
Take a look here: https://getcomposer.org/ for how to get started.

I'm creating a system that would work on call same function names from dynamic created php files.
The file structure is as bellow :
/root/caller.php //{uses pthreads & process multi simultaniously}
/root/rules/mode1.php
/root/rules/mode2.php
/root/rules/mode{n}.php // goes till n , so unlimited
Caller.php reads data from db and calls mode{n} accordingly. Sometimes there are chances to call multiple of rules at a point of time.
Sample of caller.php {written on OOPS}
foreach ($result as $row){
$mode = $rom->modeNum;
include 'rules/mode' . $mode . '.php';
call_fuction_inside_mode();
}
Sample of mode{n}.php {procedural programming}
function call_fuction_inside_mode(){
//..Custom function depending upon mode{n}
}
This won't function properly, because caller.php would include same function name again and again.
Please note :
I do not want to play with rename function with pecl, as all includes would be required
I have tried calling mode{n}.php by introducing another file "proxy.php"
And proxy.php works in below pattern
caller.php -> curl 127.0.0.1/proxy.php?mode={n} -> calls as defined
But this is not efficient way to do this when dealing with >500 requests per sec on micro server. I noticed many requests are killed and there's problem with order number. My target is to achieve this with least memory usage and 100% utilization of provided cpu resources.
I'm confused and so curious to find the solution I should be dealing here.
create an interface called Mode in Mode.php:
interface Mode{
public static function AcivateMode();
}
and include Mode.php into your code, then change the code in your mode{n}.php to encapsulate your function into classes that implements the interface Mode like so:
class Mode1 implements Mode {
public static function AcivateMode() {
//..Custom function depending upon mode{n}
}
}
then modify your foreach to activate the modes like:
foreach ($result as $row){
$mode = $rom->modeNum;
include 'rules/mode' . $mode . '.php';
call_user_func("Mode$mode::AcivateMode");
}
OR
you can use the namespaces approach by adding the namespace to each of your mode{n}.php files like so:
mode1.php
namespace Mode1;
function call_fuction_inside_mode(){....}
and calling the function using:
call_user_func("Mode$mode\call_fuction_inside_mode");
that worked for me, hope it's gonna be helpful :)
Regards,
I am creating a cron job that will run every few minutes and it will read from database data to see which function needs to be called and act accordingly to the data but half the crons are written in codeigniter and the other half in native php.
Is there any way to do this? I have been googling but the anwser. I came up with is that it is impossible. I tried changing directory and than including or requiring index.php from the codeigniter, in which the function is that i need to call.
while doing this if my class is written in native php, It returns some errors that don't make sense and if I correct those errors, I would say that half the system function from codeigniter would be gone. It would still be a question if it will work even then.
If my class is written in codeigniter, when I include index.php, it just breaks. No errors no response or it says that the "ENVIRONMENT" variables are already defined. Thus I have been looking for a way to undefine those variables from config file or overwrite them to null or empty string but nothing works.
If you have any ideas it would be much appreciated.
I saw a question question link about some cron jobs in php where the user #michal kralik gave an answer about what i am doing in general with database and one cron class that will call other crons (coould use help for that too).
btw forgot to mention that using curl and exec will not work, because on our servers they sometimes just stop working for no reason.
UPDATE 1:
this is my class currently after so many tries:
class Unicron extends MY_Controller {
public $config;
function __construct() {
parent::__construct();
}
public function init(){
$config['base_url'] = "http://localhost/test";
define('EXT_CALL', true); // Added EXT_CALL constant to mark external calls
$_GET['controller/method'] = ''; // add pair to $_GET with call route as key
$current = getcwd(); // Save current directory path
chdir('C:/inetpub/wwwroot/test/'); // change directory to CI_INSTALLATION
include_once 'index.php'; // Add index.php (CI) to script
define('BASEPATH', 'C:/inetpub/wwwroot/test/system/');
$this->load->library("../../application/controllers/controller.php");
$job = new $this->controller->Class();
$isDone = $job->exportExcel(somekey);
echo $isDone;
$CI =& get_instance(); // Get instance of CI
$CI->exportExcel('baseparts', 'exportExcel');
// FOR STATIC CALLING!!
//$CI->method('controller','method');
//replace controller and method with call route
// eg: $CI->list('welcome','list'); If calling welcome/list route.
//$OUT->_display(); // to display output. (quick one)
// Or if you need output in variable,
//$output = $CI->load->view('VIEW_NAME',array(),TRUE);
//To call any specific view file (bit slow)
// You can pass variables in array. View file will pick those as it works in CI
chdir($current); // Change back to current directory
echo $current;
}
where i try to define BASEPATH it does not define it nor override the previous value.
In the index.php of other codeigniter i put:
if(!defined('ENVIRONMENT'))
define('ENVIRONMENT', 'development');
this way i resolved my issue with ENVIRONMENT already being set error.
this is a few things i found and combined together, hoping it could work but still when i call it via command line it shows nothing (even tried echo anything everywhere and nothing).
This may be a long comment rather than a answer as the code supplied requires a lot of work to make it useful.
Running multiple instances of 'codeigniter' - executed from codeigniter.
Using the 'execute programs via the shell' from PHP. Each instance runs in its own environment.
There are some excellent answers already available:
By default the PHP commands 'shell' wait for the command to complete...
732832/php-exec-vs-system-vs-passthru.
However, we want to 'fire and forget' quite often so this answer is quite useful...
1019867/is-there-a-way-to-use-shell-exec-without-waiting-for-the-command-to-complete
All i did was use this show an example of how to use 'codeigniter' to do this. The example was the 'Hello World' cli example from user manual. The version of ci is 2.1.14. I haven't used 'ci' before.
It is tested and works on 'PHP 5.3.18' on windows xp.
As well as the usual 'Hello World' example, i used an example of a a command that uses 'sleep' for a total of 20 seconds so that we can easily see that the 'ci' instances are separate from each other while executing.
Examples:
<?php
class Tools extends CI_Controller {
// the usual 'hello world' program
public function message($to = 'World')
{
echo "Hello {$to}!".PHP_EOL;
}
// so you can see that the processes are independant and 'standalone'
// run for 20 seconds and show progress every second.
public function waitMessage($to = 'World')
{
$countDown = 20;
while ($countDown >= 0) {
echo "Hello {$to}! - ending in {$countDown} seconds".PHP_EOL;
sleep(1);
$countDown--;
}
}
}
'ci' code to run 'ci' code...
<?php
class Runtools extends CI_Controller {
/*
* Executing background processes from PHP on Windows
* http://www.somacon.com/p395.php
*/
// spawn a process and do not wait for it to complete
public function runci_nowait($controller, $method, $param)
{
$runit = "php index.php {$controller} {$method} {$param}" ;
pclose(popen("start \"{$controller} {$method}\" {$runit}", "r"));
return;
}
// spawn a process and wait for the output.
public function runci_wait($controller, $method, $param)
{
$runit = "php index.php {$controller} {$method} {$param}";
$output = exec("{$runit}");
echo $output;
}
}
How to run them from the cli...
To run the 'ci' 'nowait' routine then do:
php index.php runtools runci_nowait <controller> <method> <param>
where the parameters are the ci controller you want to run. Chnge to 'runci_wait' for the other one.
'Hello World: 'wait for output' - (ci: tools message )
codeigniter>php index.php runtools runci_wait tools message ryan3
Hello ryan3!
The waitMessage - 'do not wait for output' - (ci : tools waitMessage )
codeigniter>php index.php runtools runci_nowait tools waitMessage ryan1
codeigniter>php index.php runtools runci_nowait tools waitMessage ryan2
These will start and run two separate 'ci' processes.
im currently working on some sort of upload with automatic video conversion. At the moment i am executing a php script via php shell command after the upload is finished so the user doesn't have to wait until the conversion is completed. Like so:
protected function _runConversionScript() {
if (!exec("php -f '" . $this->_conversionScript . "' > /dev/null &"))
return true;
return false;
}
Now in my conversion script file i am using functions from another class "UploadFunctions" to update the status in the database (like started, converted, finished...). The problem there is though that this UploadFunctions class inherits from another class "Controller" where for example the database connection gets established. Currently i am using spl_autoloader to search specific directories for the files needed (for example controller.php), but because the conversion script is out of context with the whole autoloader stuff it doesn't recognize the Controller class and throws an fatal php error.
Here is some code from the conversion script:
require_once('uploadfunctions.php');
$upload_func = new UploadFunctions();
// we want to make sure we only process videos that haven't already
// been or are being processed
$where = array(
'status' => 'queued'
);
$videos = $upload_func->getVideos($where);
foreach ($videos as $video) {
// update database to show that these videos are being processed
$update = array(
'id' => $video['id'],
'status' => 'started'
);
// execute update
$upload_func->updateVideo($update);
.........
Am i doing this completly wrong or is there a better way to accomplish this? If you need more code or information please let me know!
Thanks a lot
Here is my spl_autoload code:
<?php
spl_autoload_register('autoloader');
function autoloader($class_name) {
$class_name = strtolower($class_name);
$pos = strpos($class_name ,'twig');
if($pos !== false){
return false;
}
$possibilities = array(
'..'.DIRECTORY_SEPARATOR.'globals'.DIRECTORY_SEPARATOR.$class_name.'.php',
'controller'.DIRECTORY_SEPARATOR.$class_name.'.php',
'..'.DIRECTORY_SEPARATOR.'libs'.DIRECTORY_SEPARATOR.$class_name.'.php',
'local'.DIRECTORY_SEPARATOR.$class_name.'.php'
);
foreach ($possibilities as $file) {
if(class_exists($class_name) != true) {
if (file_exists($file)) {
include_once($file);
}
}
}
}
?>
I have my project divided into subfolders wich represent the functionality, for example upload, myaccount and gallery.. in every subfolder there are also 2 other folders: controller and local. Controller is the class controlling this part (upload for example) and local is the folder where i am putting the local classes wich are needed. The controller class gets called from the index.php wich is located in the sub-project folder. "libs" and "global" are just projectwide classes, like database, user and so on.
This is an example of my folder structure:
www/index.php // main site
www/upload/index.php // calls the controller for upload and initializes the spl_autoload
www/upload/controller/indexcontroller.php // functionality for the upload
www/upload/local/processVideo.php // this is the conversion script.
I am fairly new to spl_autoload function. In my opinion the spl_autoload is not getting called if my script is calling: "php -f processVideo.php", isn't it?
PHP relative paths are calculated from the path where PHP binary is called.
I suggest you to use __DIR__ constant to avoid that behavior
http://php.net/manual/en/language.constants.predefined.php
I was actually able to resolve the issue. I had to include the spl_autoload_register function inside the conversion script so that it was able to locate the files. This was an issue because the conversion script is not build into my framework an so it isn't able to load the classes from the framework autoloader.
I'm starting off with both php and Joomla development, and finding it difficult working within Joomla to do some fairly simple stuff. Went through the Joomla MVC example and Lynda (and have built a few simple views so far).
I have a helper file/class/function that outputs all the userids that exist in the "completed" table so I can display a link for either a new record based on that user or edit an existing user's record.
I've already used a different function in this helper file successfully in a different part of the component ( Joomla: Write and call a helper function in a component ).
When I do the same thing in the model, I'm getting this: "Fatal error: Call to protected method JModel::_createFileName() from context 'JView' in C:\wamp\www\ilplocal\libraries\joomla\application\component\view.php on line 773". When I try it in the view, works fine - but I need the output in the model.
Code:
lookups.php
abstract class LookupHelper {
public function other_functions($vars){
...
}
public function completions_exist() {
$db =& JFactory::getDBO();
$query = $db->getQuery(true);
$query->SELECT(' #__completed.completed_userid as UserID');
$query->FROM (' #__completed');
$query->GROUPBY (' #__completed.completed_userid ');
$db->setQuery($query);
$result = $db->loadResultArray(0);
return $result;
}
}
In the model:
$completions_exist = Jview::loadHelper('lookups');
$completions_exist = LookupHelper::completions_exist();
This line is throwing the error: $completions_exist = Jview::loadHelper('lookups');
I've found some really vague references to something called JLoader::register to pull in helper functions but can't find any good documentation on that in Joomla except for everyone saying to just use that. SO I tried using it like so:
JLoader::register('LookupHelper', dirname( JPATH_COMPONENT_ADMINISTRATOR).DS.'helpers'.DS.'lookups.php');
$completions_exist = LookupHelper::completions_exist();
which throws this error: "Fatal error: Class 'LookupHelper' not found in C:\wamp\path\to\model\not\to\lookups.php. Tried manipulating the JLoader::register(everything here) and it doesn't effect the path of the error message.
Thoughts? Why does it work in a view and not in the model? How do I use the helper functions within a model?
Thanks!
#####EDIT
Thanks to #cppl looks like it's a path issue with the second bit of code. Also I read that the .DS. notation will be phased out in future versions - so the code that's working is:
JLoader::register('LookupHelper', JPATH_COMPONENT_ADMINISTRATOR.'/helpers/lookups.php');
$completions_exist = LookupHelper::completions_exist();
Lets break this down:
In Joomla! your components helper file should be in `/mycomponent/helpers/lookup.php'
JLoader:: is the Joomla! way to do it, but you could just as easily use PHP's require_once eg. require_once JPATH_COMPONENT_ADMINISTRATOR.'/helpers/myfunctions.php';
Is your path right? - you're providing dirname(JPATH_COMPONENT_ADMINISTRATOR).DS.'helpers'.DS.'lookups.php' but you've wrapped the path to your component in dirname which will the parent element of the path only. So JLoader is looking in /administrator/helpers/lookups.php.
JPATH_COMPONENT_ADMINISTRATOR is initialised as part of Joomla!'s renderComponent() call in it's JComponentHelper class if you apply dirname to it when it's not setup you will get back a dot (ie. current directory) so in the model you could would be passing ./helpers/lookups.php to the JLoader call.
You can call helper within model by following method:
JLoader::import('helpers.events', JPATH_COMPONENT);
this will include the file helpers/events.php from the component directory.
$_helper = new EventsHelper();
echo $_helper->getAnyInsideMethod();exit;
How do I go about integrating Simpletest with Kohana 3? I have checked out this answer but I like to use the autorun.php functionality from SimpleTest.
After some hours of looking over the code, I have discovered how to do it
Create a new copy of index.php, and name it test_index.php
disable the error_reporting line in test_index.php
Create a new copy of bootstrap.php, and name it test_bootstrap.php
comment out the request at the bottom
Ensure that test_index.php includes test_boostrap.php instead of bootstrap.php
Add simpletests to the directory structure
Write the test case - include 'test_index.php' and 'autorun.php' (from simpletests) and code test cases as usual.
My example:
<?php
include_once ("../../test_index.php");
include_once ("../simpletest/autorun.php");
class kohana_init_test extends UnitTestCase
{
function testTrue()
{
$this->assertTrue(true);
}
function testWelcome()
{
$response = Request::factory('main/index')->execute()->response;
$this->assertEqual($response->content, 'testing');
}
}
?>
Some notes: the $response variable depends on if you are using a View or pure text output. If you are using the template controller or a view, then $response is the view which you have used to render the content. Variables in the view are avaliable , as shown above (the variable content is defined inside the view).
