PHP - Exec() Open Application For Local User

Is it possible to read from a file that is located on the user's local machine and not on the server?  I have a CSV file that is about 70MB that I have to parse through and insert the data into a database.  I have no problem doing this if I hard code the path to the file.  Is there a way to get the path of the file that the user wants to be parsed into the database?  I don't think uploading the file would be a good idea because, like I said, it is 70MB and is nearly 2 million lines.  Simply parsing the file takes long enough without throwing in upload time..

I have hardware setup to preform an action on camera when i enter a url into the address bar. Pretty much you will be able to feed tarantulas.  I'd like to setup a button that my user can click that will active the url without being moved off of the current page.

I can't figure out how to stop the browser from following the link to a blank page. It messes the whole thing up because the feeder only runs for a second and if you get sent to the blank page and have to navigate back the the live video feed page you could miss the feeding.

Thanks for the help

Hi guys

Do you guys know if possible to open an external URL without actually displaying this to the user? We have a service where we wish to open an external URL which triggers sending out an SMS to the user.  However..we cannot display the url opened to the user as it shows our username etc with the sms provider.

basically the url looks like this:   

https://www.smsprovider.com/username=OurUsername&password=******&smsMsg_to_send=blablablablabla

Is it possible to "trigger" this URL without letting our users see it?

Thanks in advance for any help you may provide

i want a code in php to check if user open this page 

Hi,
I need a small help. Here is my situation.

I am using a MVC application (e.g. Joomla or Drupal) which has a .htaccess redirect rule that all requests are passed through index.php file. That's normal and this is my main application. Now I installed another application within the application folder structure. What I want do do here is to allow opening the third party application URLs after one logged into my main application.

Can anybody provide me some pointers to do the same? Please let me know if you need any further information on this. Any solution irrespective of framework will work.

Thanks!

Hello, I was just seeing if someone could push me in the right direction. I have a form that uploads items to a database and it also includes uploading images to a directory as a part of that. That all works, but I was thinking for security it'd be best not to leave that directory as 0777 for permissions. In researching this I found the exec() function. I'm still figuring out the relation of who the permissions are associated with and why. All I know is if the directory has 0777 for permissions my script works just fine. I was just seeing if using exec to change the permissions during the process of uploading the images and then change back would be cumbersome and leave open other problems (there won't be any user-based input being passed to that) or if that actually would be the way to go for this.

Thanks!

i have a bash script that i was running with cron jobs:


#! /bin/bash
 start=1000
 homedir="/home/alin/NetBeansProjects/Fragger2"

 numberofprocess=`expr $start + $2`

 i=$start

 currentnumber=`ps ax |  grep index | grep -c php`

case "$1" in
  start)

        while [ $i -lt $numberofprocess ]
                do
                   if [ `ps axo cmd | grep  index | grep php | grep -c $i` -lt 1 ] ; then

                   
                   /server/php/bin/php $homedir/index.php $i &
                   
                   fi;
                   
                   i=`expr $i + 1`
                   
        done
       ;;
   stop)
        while [ $currentnumber -ne 0 ]
        do
                kill -9 `ps ax | grep php | grep index | awk {'print $1'} | head -n 1`;

                currentnumber=`ps ax |  grep index | grep -c php`
        done
        
      ;;

  *)
echo "Usage : " $0 "start|stop"
        ;;

esac
exit 0



and it was working fine,

now i'm tring to make it run from a page .


if(isset ($_POST['stop'])){
    $conn->update("update `links` set `proccess`=0 ");
    exec("/home/alin/NetBeansProjects/Fragger2/Trans stop 0");
}


if(isset ($_POST['start'])){
    if(!preg_match("/^[0-9]+$/", $_POST['proccess']))
            echo "proccess should be only a number!";
    
    exec("/home/alin/NetBeansProjects/Fragger2/Trans start ".$_POST['proccess']);
}


and i don't know why it is not working,

i have set for this folder all the permision for this folder  "chmod -R 777 /home/alin"

it doesn't stop running and i can't figure out why

i have to kill the procces from the comand line to stop

I'm trying to open a batch file in php with these contents:
Code: [Select]
@echo off
java -classpath rscd.jar;lib/mina.jar;lib/xpp3.jar;lib/slf4j.jar;lib/xstream.jar;lib/hex-string.jar; org.rscdaemon.server.Server
pause

My PHP code is simply
Code: [Select]
$run = "C:\\Users\\Zorian\\Desktop\\EasyRSC\\Server\\run-win.bat";
echo exec("cmd.exe /c " . $run);

It should open up a java applet, instead it just echos:
Code: [Select]
Press any key to continue . . .

Hi guys!

I have a php script that works and outputs info:

<?php
echo exec("uptime");
?>

and another that doesn't output anything:

<?php
echo exec("MP4Box");
?>

Why?

I figure I’m doing something basic wrong.
I have this php code.

$cmd = “at $wtime $wdate <<< “sftp -a -r -P xxx xxx@xxx.xxx.net:”.$file.” /mnt/TRFR” ;
exec ($cmd);
echo $cmd;

the “at” command is never generated atq returns blank. But if I copy the output of the echo from the web page into bash the “at” job gets created.

 

What am I missing here?

Hi all.

I tried to execute command below
` echo '<br/>'.$data. " >=> " . exec("java -jar encrypt.jar ".$data." ".$privateKey, $key);`
it's look like we run `java -jar encrypt.jar 192.168.101.1BBB10052 ssdsds`
I can run this command on the server by ssh but when I use PHP code, it's nothing.
so I need to enale the exec function or different command on this version?

Hi,

I have a java file that needs to be executed from my php script, the command I have in it works perfectly when I execute directly in the command line, but when I execute it from php it returns this: array(0) { }

I have tested that the exec works by using antiword, which does return results as expected, but its not working for the code below.
But I would much rather use apache tika.

Also your thoughts on whether this is good practice please. I am using this to extract text from CV's and store that in the db to be able to search through. I need to extract from: pdf, doc, rtf and docx. this is the only tool I have found that can handle them all.

your help on the exec problem and any suggestions will be much appreciated.

Code: [Select]
<?php
   exec('java -jar /etc/tika-app-1.0.jar -t /var/www/html/cvdatabase/400001.doc', $output);
   var_dump($output);
?>

Hello i am trying to execute a linux program for every line of a textarea

Code: [Select]
        $text = $_POST['links'];
       
        $text = htmlspecialchars($_POST['links']);
        $text = nl2br($text);
       
        foreach(explode("\n",$text) as $row)
        {
                $result = NULL;
                $command = 'the command';
                exec($command,&$result);
                echo $result[0]."<br>";
        }
but this always print the result for last line of text area
for example if there are 3 lines it print 2 blanks and 1 result...
whats wrong??

 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.
