PHP - Executing Powershell Script From Php

I am a bit desperate about this problem that I have been trying to solve for several days now.

I'm trying to run a Python script from the exec() function in php. The script is called but the print job is never executed. 

This process has been running for several years and for no clear reason it suddenly stopped working.

On my home computer, it works without any problem. In my virtual machine, nothing happens. The print() functions present in the script are well displayed by the return value received by php but the printing is not executed.

The virtual machine is a test environment, in production it is also an physical machine.

PHP

<?php
        exec("py C:\xampp\htdocs\test\test.py", $out, $res);
        echo "<pre>";
        print_r($out);
    	echo "</pre>";
    echo "<pre>";
    	print_r($res);
	echo "</pre>";
?>

PYTHON

if __name__ == "__main__":
  try:
    filename = "C:/xampp/htdocs/test/test.pdf"
    win32api.ShellExecute(0, "print", filename, None, ".", 0)
    except Exception as e:
      print(f "An error occured during print_pdf : {e}")

The two environments are approximately the same:
* Build 1909
* Python 3.9.5
* Apache 2 & php > 7
* local user member of the administrators group
* local user owner of the apache2 service
* Same printer configured by default

I'd like to point out that running the script directly from the CLI works on both machines.

On the problematic machine, exec() only returns the result of print(..) 

I already opened a thread a few months ago about this problem but received no response.

Thank you in advance.
 

I'm using PHP on a windows box to execute some powershell scripts, my only problem is that the browser hangs on the request.
The browser will continue to hang until I goto Task Manager and kill Powershell.exe, then my results are returned as expected.

I've tried to execute an "exit" command after executing my Powershell commands, but that doesn't seem to work.


Anyone used Powershell before, or have any ideas on how I could handle this otherwise?

Here's my code:
Code: [Select]
$output = array();
exec("powershell get-service", $output);
print_r($output);


Thank you!

 have a executable binary to which i pass some dynamic values as hostname,host id,server name,server id and a text field value.

Now i call this binary using exec or shell_exec functions in PHP to stimulate Command executions as a admin.

But i am able to invoke the binary and not able to use psexec service of windows.

I get logs and DB entries successfully but i also have a xml push operation in psexec call that is required.

the format is like ::

exec($url,$output,$return_var);

url is the command path with parameters .
output is an out param and return is the code on execution

this is executed in PHP and i want this binary to generate the same output as done from CLI .

Currently i guess it's a permission issue with shell that disallows psexec call.

How do i invoke the binary with psexec access outside PHP on command shell

I have set access privilege of Powershell  to "unrestricted" so that any script can be executed.

Still it hangs up somewhere in th script causing problems in copying XML file.

Powershell psexec is required in the process and i need to track down the root cause so that php side scripting of binary is successfull.

Please let me know about your ideas in fixing this.

I am using google and trying examples ,but i havent got any feasible solution.

Hope some expert advice can guide me out of this.

I am trying to use some php code inside of an html document and it does not work. I have a script.php file that executes perfectly when I try and use it. Here is the code I am currently using:

Code: [Select]
<?php
 echo "<title>";
 echo "the Homepage!";
 echo "</title>";
?>
Any suggestions would be great.

I have the following query where $userid is about 100,000 userids separated by commas.

Code: [Select]
<?
$getpostid=mysql_query("SELECT DISTINCT post.username,post.threadid,thread.threadid,thread.forumid from post,thread WHERE post.username='$username' AND post.threadid=thread.threadid AND post.userid IN ($userid) AND thread.forumid IN ($forumids)") or die (mysql_error());
?>can i just print all the usernames from above result separated by ';' without looping it multiple times?
 
Could someone help me out how to do above in an efficient manner?

I'm tired and want to sleep so my mistakes are getting lots now. Anybody awake that can explain my problem with the code below. 

<?

function directoryToArray($directory, $recursive) {
        $array_items = array();
        $i = "0";
        if ($handle = opendir($directory)) {
                while (false !== ($file = readdir($handle)) && $i < "3") {
                        if ($file != "." && $file != "..") {
                                if (is_dir($directory. "/" . $file)) {
                                        if($recursive) {
                                                $array_items = array_merge($array_items, directoryToArray($directory. "/" . $file, $recursive));
                                        }
                        } else {
                                        $file = $directory . "/" . $file;
                                        $array_items[] = preg_replace("/\/\//si", "/", $file);
                                        $i++;
                                }
                        }
                }
                closedir($handle);
        }
        natsort($array_items);
        return array_reverse($array_items);
}
$data = directoryToArray('images/screenshot/', TRUE);
print_r($data);
?>


What I want is for the while loop to stop after 4 hits and exit and give me the return results. But now it continue until readdir end.

I am playing around with php but the script doesnt execute to the last point and with no error... 

 

What i am trying to do is checking the input of the user and comparing it what is in db and then applying conditions. So i have 2 files. update.php and home.php. 

home.php is my html form page and i included 'update.php' in it

In my update.php, i have these codes

 

<?php

error_reporting(E_ALL);


include_once('database.php');

if(isset($_POST['submit']))

{

$q = $_GET['q'];

$next = $q + 1;

if($q == 26)
{
echo '<h2>You have Completed the Exam.Congrats!!</h2>';


}
elseif($q <= 25){
    
$sql = "SELECT * FROM Students WHERE Email=?";
$stmt = $conn->prepare($sql); 
$stmt->bind_param('s', $_SESSION['login']);
$stmt->execute();
$result = $stmt->get_result(); $row = $result->fetch_assoc();

$Mark = $row['Mark'];


$Correct = $Mark + 1;


$Fail = $Mark + 0;

  
$sqlb = "SELECT * FROM Answers WHERE qid = ?";
$stmtb = $conn->prepare($sqlb); 
$stmtb->bind_param('s', $q);
$stmtb->execute();
$resultb = $stmtb->get_result();

$rowb = $resultb->fetch_assoc();

$Answer = $rowb['Answer'];

$Pick = $_POST['ans'];

if($Pick ==  $Answer)

{
  
  
    
  $sqld = "UPDATE Students SET Mark=? WHERE Email = ?";
$stmtd = $conn->prepare($sqld); 
$stmtd->bind_param('ss', $Correct,$_SESSION['login']);
$stmtd->execute();
$resultd = $stmtd->get_result();  


   echo "correct" ;
}

}
else

{
    
    echo 'Ate';
echo "<script type='text/javascript'>document.location.href='home.php?q='.$next.';</script>";
}

}//post submit

?>

The else statement doesnt run. so it keeps reloading the same page.   

  Also i want to ask why i keep getting the value of 2 for my $Correct variable stored on the database into column Mark for a single correct question instead of 1. What could be wrong?

Lastly, i dont want the script to run if the browser is edited by the user by changing the value of $q from the browser, because i am using get method, is there a way to do that.

Please be nice with your comments. Thanks in advance.!!!

OK, so I have the following file that has database functions:

<?php

function dbDelete($param){
$conDelete = mysql_connect($url,'username','password',true);
mysql_select_db('my_db',$conDelete);
mysql_query($param,$conDelete);
mysql_close();
   if(isset($conDelete)){
   mysql_close($conDelete);
   }
}
?>

I include the above file in a session handling file.  But for some reason the new file can't call the above function as follows:
<?php
include_once 'the above stated file';
function timeOut(){
        dbDelete("DELETE FROM acctussessi WHERE acctussessi_usid = '$sessius[0]'");
   $_SESSION = array();
   setcookie(session_name(),'',time()-4200);
   session_destroy();
}
//CHECK FOR TIMEOUT REQUEST
switch($_GET['xyz']){
   case 'timeout':
   timeOut();
   header("Location: /?xyz=timedout");
   break;
   case 'logout':
   timeOut();
   header("Location: /?xyz=loggedout");   
   break;
   case 'refresh':
   dbUpdate("UPDATE acctussessi SET acctussessi_time = ".time()." WHERE acctussessi_unid ='".$token."'");   
   break;
}
?>

dbDelete isn't being called inside of the TimeOut() function.  The only way it works is by doing the following:

<?php
function timeOut(){
   $_SESSION = array();
   setcookie(session_name(),'',time()-4200);
   session_destroy();
}
//CHECK FOR TIMEOUT REQUEST
switch($_GET['xyz']){
   case 'timeout':
      dbDelete("DELETE FROM acctussessi WHERE acctussessi_usid = '$sessius[0]'");
   timeOut();
   header("Location: /?xyz=timedout");
   break;
   case 'logout':
      dbDelete("DELETE FROM acctussessi WHERE acctussessi_usid = '$sessius[0]'");
   timeOut();
   header("Location: /?xyz=loggedout");   
   break;
   case 'refresh':
      dbUpdate("UPDATE acctussessi SET acctussessi_time = ".time()." WHERE acctussessi_unid ='".$token."'");   
   break;
}
?>
But this is annoying and repetitive.  What is going on?

Thanks in advance.

Hey guys!
My current employer contracted someone to create a script for him. (The script itself is to create a serial number for a piece of software) It's just a PHP script that executes a file and retrieves its output.
Now I've never worked with exec() in PHP, and I don't have a reliable environment to test it in. I compiled apache2 and php 5.0.4 and set them to run on a Macintosh (10.3.9) in the office, but I'm sure I've missed some crucial setup stage (mainly, I'm missing php.ini. I did a php -i | grep php.ini to find it, and it says it is in /etc/, but when I look in my PHP/etc folder, only pear.conf is there!). PHP and apache both appear to be working fine, though.

When I try and run the PHP script that executes the .ELF file, I get a blank page. Is this because I'm running it in OS X?  should I be running it in Linux?
Also, I don't know how to Enable exec() on my server, or to see if it's enabled. Basically, I just need someone to walk me through the basics of this. The script and executable SHOULD work fine because the contractor got it working fine.
Below is the script, and attached is the executable.
Thanks! :3

<?php

/*
inUID = 456890
inSerialNumUID = 123456
inMachineID_s = &6dA-8P@K-Xsq
*/

$p1 = "456890";
$p2 = "123456";
$p3 = "\&6dA-8P@K-Xsq";

exec("./create_activation_code.elf $p1 $p2 $p3", $output);

foreach ($output as $output_str)
{
echo $output_str."<br>";
}

?>

hey guys im sure this is possible im wondering how a user can execute a mysql query by a click of a button but without the page reloading...thanks guys

In a PHP file [php_one.php], I wrote some PHP code that contained a form.  I used ECHO to write the HTML inside of the PHP tags.

On another PHP page [php_two.php], I wanted to show the code that was used to create the first page [php_one.php].

My first effort provided an interesting result, since the PHP code was readable.  However, all HTML code was visible in its executed form.

There was an actual input field and a submit button (not the code used to produce them) in the context of my coding.

I have tried using:

file_get_contents("FILE")
$array = file("FILE")
readfile("FILE")

All results were similar and carried the same problem.

How can I view code so that even the HTML is visible as code?

Hi,

Hi all,     This is just an experiment to make sure that I can get data from a Stored Proc 'IF' and when I need to, so it's basically a THOUGHT EXERCISE.   MSSQL 2014     I'm a noobie and need a hand, I've managed to get my Instance connected to the internet and I can query it using PHP and SQL, I can also look at views with no problem.     I have it working as an "ADODB.Connection" and like I said it connects and I can query data and display results.     Now I have coded a Stored Proc "GetMonthDays" in Sql Server:   Which returns days 1 through xxx in a given month and also returns the Day name  eg... Sat for each date     2014-01-01 Thurs   2014-01-02 Fri   etc...     It works perfectly and very fast so All cool with that side BUT...     I want to be able to query the Database through a Stored Proc, I've spent all day trying to find a way to get this to work and I've hit a wall   Can anyone please tell me IF it's A. possible and B. maybe if they are really really nice and share with me a code example that I can change to fit my needs ?     This T-SQL returns what it needs to     Begin
  EXEC dbo.qselGetMonthDays '2015-01-01'
  End
      Cheers     JD

i'm creating a small app for someone who wants to control the content of each page from a DB.

effectively it'd be a template file with header, footer, etc all pre-built, and the content area supplied from a TEXT field in a MySQL table - basically the same idea wordpress uses.

this is all fine, but a couple pages would require some php - e.g., a list of events or users or articles, whatever, that are managed in different tables.

i can do this with eval - something like:

Code: [Select]
function render_content($string) {
ob_start();
eval("?>$string<?php ");
$returns = ob_get_contents();
ob_end_clean();
return $returns;
}
but i wonder if there's a better way.  i can probably limit whatever code needs to be executed in include files, so i thought maybe include some arbitrary tag and use regexp to parse it out...  maybe modeled after a conditional comment, e.g.,

Code: [Select]
<!--[include]some-file.inc.php-->
// or even...
<include>some-file.inc.php</include>

but, again, not thrilled with the approach, and wondered if anyone had a better idea.

i should probably mention that it's not going to be a "content or include" setup - it probably won't be one or the other, exclusively, and is likely to be a mix on those pages that require it - the php might need to appear before, after, or in the middle of whatever arbitrary markup the user happens to supply, e.g.

Code: [Select]
<h1>This is a list of stuff</h1>
<p>Some explanation lorem ipsum dolor sit ahmet.</p>
<?php include('some-file.inc.php'); ?>
<em>But this caveat applies to the above list.</em>
<div>
  Something totally unrelated.
  <img src="pic.jpg" />
</div>
not sure I explained that very well, but hopefully the concept comes across.

Hi guys, im having a problem, in my phpfile were is generated the action code form the contacts form is giving me a lot of trouble, im receiving a lot of blank emails, first i thiked was bots,im usign a captcha, but then i notice another thing, when i put the name of the file that generates the action in the browser this loads it and send it the black email.
