PHP - Exec()

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);
?>

I would like PHP to kick off the following command:
Code: [Select]
arp -a|sed 's/ /,/g'>arp.csv
I also have an executable makeArpFile.sh:
Code: [Select]
#!/bin/bash
arp -a|sed 's/ /,/g'>arp.csv
And I have tried executing it in php with the following:
$arp = exec("bash makeArpFile.sh", $output, $exit_code);
echo("Last line: " . $arp . "\n");
echo("Output: " . $output . "\n");
echo("Exit Code: " . $exit_code . "\n");
/*returns:
Last line: 
Output: 
Exit Code: 127
*/

I also tried just plain old:
$arp = exec("makeArpFile.sh", $output, $exit_code);
echo("Last line: " . $arp . "\n");
echo("Output: " . $output . "\n");
echo("Exit Code: " . $exit_code . "\n");
/*returns:
Last line: 
Output: 
Exit Code: 127
*/


I can run plain old arp>arp.txt but I really need it formatted in BSD style (arp -a>arp.txt) in order to be able to parse it properly later.

Any thoughts?

EDIT:
for fun I made a useBash.sh script that executed "bash makeArpFile.sh" still no luck.

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?

 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.

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

I've got a mailing list (uses DadaMail) which provides a perl script (subscribe_email.pl) so that I can pass subscribers to it thorugh a PHP script.

Info he http://dadamailproject.com/support/documentation-5_0_1/COOKBOOK-subscriptions.pod.html#command_line_utility___subscribe_email_pl

The trouble is I can get it working when variables are passed to it via URL query strings, but when I try to hard-code variables into it it stops working. I can't see any reason for this, it's got me really confused.

This works: -

Code: [Select]
<?php
// example usage: -
// http://www.domain.com/ds1.php?sendto=user@domain.com&title=Mr&forename=John&surname=Doe&company=None&country=UK

if (isset($_GET['sendto'])) {
$email = $_GET['sendto'];
}

if (isset($_GET['title'])) {
$title = preg_replace("/[^A-Za-z ]/", "", $_GET['title']);
}

if (isset($_GET['forename'])) {
$forename = preg_replace("/[^A-Za-z\-. ]/", "", $_GET['forename']);
}

if (isset($_GET['surname'])) {
$surname = preg_replace("/[^A-Za-z\-. ]/", "", $_GET['surname']);
}

if (isset($_GET['company'])) {
$company = preg_replace("/[^A-Za-z()\-.& ]/", "", $_GET['company']);
$company = str_replace('&', 'and', $company);
}

if (isset($_GET['country'])) {
$country = preg_replace("/[^A-Za-z\-.& ]/", "", $_GET['country']);
$country = str_replace('&', 'and', $country);
}

if (isset($email)) {
$exec_command = 'perl ./subscribe_email.pl --list mylist --email '. $email;
if (isset($title)) $exec_command .= ' --fields title '. $title;
if (isset($forename)) $exec_command .= ' --fields forename '. $forename;
if (isset($surname)) $exec_command .= ' --fields surname '. $surname;
if (isset($company)) $exec_command .= ' --fields company '. $company;
if (isset($country)) $exec_command .= ' --fields country '. $country;
exec(escapeshellcmd($exec_command));
} else {
echo 'Nothing to do';
}
?>
The mail address and all the parameters are passed to the subscribe_email.pl script.

But, this doesn't work: -

Code: [Select]
<?php
$subscriber_email = 'user@domain.com';
$subscriber_title = 'Mr';
$subscriber_forename = 'John';
$subscriber_surname = 'Doe';
$subscriber_company = 'None';
$subscriber_country = 'UK';

if (isset($subscriber_email)) {
$email = escapeshellcmd($subscriber_email);
}

if (isset($subscriber_title)) {
$title = preg_replace("/[^A-Za-z ]/", "", $subscriber_title);
}

if (isset($subscriber_forename)) {
$forename = preg_replace("/[^A-Za-z\-. ]/", "", $subscriber_forename);
}

if (isset($subscriber_surname)) {
$surname = preg_replace("/[^A-Za-z\-. ]/", "", $subscriber_surname);
}

if (isset($subscriber_company)) {
$company = preg_replace("/[^A-Za-z()\-. ]/", "", $subscriber_company);
$company = str_replace('&', 'and', $company);
}

if (isset($subscriber_country)) {
$country = preg_replace("/[^A-Za-z\-. ]/", "", $subscriber_country);
$country = str_replace('&', 'and', $country);
}

if (isset($email)) {
$exec_command = 'perl ./subscribe_email.pl --list mylist --email '. $email;
if (isset($title)) $exec_command .= ' --fields title '. $title;
if (isset($forename)) $exec_command .= ' --fields forename '. $forename;
if (isset($surname)) $exec_command .= ' --fields surname '. $surname;
if (isset($company)) $exec_command .= ' --fields company '. $company;
if (isset($country)) $exec_command .= ' --fields country '. $country;
exec(escapeshellcmd($exec_command));
} else {
echo 'Nothing to do';
}
?>
In the second example, only the list and email parameters are passed, all the others are lost (or ignored).

All that's different between the two is the way the variables are inititally set, I can't for the life of me figure out why the second one isn't working  .

Even stranger, I tried testing with just: -

Code: [Select]
<?php
exec("perl ./subscribe_email.pl --list mylist --email user@domain.com --fields title Mr --fields forename John--fields surname Doe --fields company None --fields country UK")
?>
and this doesn't work fully either (again just the list and email parameters are passed).

Unfortunately, it's the second method I need to use as it's tagged on to the end of a contact form processing script which initiates the subscription if a checkbox is left ticked...and all variables will be coming from this form script.

Any help greatly appreciated!

I want to do something like the following:

exec('open /Applications/Safari.app');



I can run exec on other commands like:


$output = exec('ls -ll);
echo $output;


And I can run the open command via Terminal, but I can't seem to run the open command via a PHP page using exec().

I've tried the permissions of the .app file at 777 and the open binary at 777.

Any suggestions?

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>";
}

?>

Folks,

I am running Linux Commands in PHP.

I am looping through the Domain list and using the below line in my Script:



exec('cp -r '.$source.' '.$destination);



I am using this in a Foreach Statment, so only the last Even in the loop getting executed, because, the loop is running too fast so the Linux command does not even get initiated, only the last even in loop goes through.

What i have done is, i have added a line after exec();

sleep(30);

This gives enough time for Linux command to get executed, but is it efficient way to handle timing liek this?

Do i need to use time_limit() or something like that?

Cheers
Natasha

is there a way to excute the system() command here but not wait for it and just let it go in the background? And something that wont boggle down the system too much? Thanks!

Code: [Select]
$this->db->insert('jukebox', $data);
echo '1';

system('ffmpeg -i ' . $id . '.mp3 -acodec libvorbis -aq 60 ' . $id . '.ogg');

Hi all,
I am a newbie to PHP. I'm trying to execute a program from my PHP script by calling the exec() function of PHP. It works fine when i try it from command line, or execute the script in command line. But when i call it from a php script in my apache, it does nothing. No errors are thrown. What i get in return is only an empty array. i'm using Ubuntu 11.10 and Apache 2.2 with PHP 5.3.3

thanks for helping me.

I'm using a program called Do It Again which is a mouse recorder. I am trying to launch a shortcut to it from my php script. Seems all is okay when I run it as a stand alone program, and is not set to have to be run by the administrator - still when I launch it from my php page I get the windows popup saying the program has crashed. "DoItAgain.exe has encountered a problem and needs to close. We are sorry for the inconvenience."

It's not the program, but something in my code:

Code: [Select]
$command= 'C:\\xampp\htdocs\poster\dia\\Monty_20.dia';
exec($command);
I also tried the following but get the windows popup error: "The Application Failed to Initiate Properly"

Code: [Select]
$command= ('START C:\\xampp\\htdocs\\poster\\dia\\Monty_20.dia');
Any help would be greatly appreciated. I've been at it for 3 hours now and I'm pulling out what little hair I have left.

I have two functions that execute an exe program (personal project for a minecraft back end.) Windows only.

 

 

First one will execute the sending of commands (THIS ONE WORKS)

	/* check to see if admin is sending commands to terminal via web */
    if(isset($_POST['command'])) {
        $content = $_POST['command'];
        
        writeMCCommandTxt($content);
        try {
            
            exec(SERVER_DIR.'mcCommand.exe',$output);
        
            
        } catch ( Exception $e ) {
            die ($e->getMessage());
        }
    }// END COMMAND ENTRY
	

This has been a head scratcher for most the week - any help or suggestions would be great!! thanks!!

MCCOMMANDS.EXE will work from both browser(php) and file manager(tested)

the STARTSERVER.EXE will NOT work from browser(php), but will work from file manager

 

The function IS being accessed - debug is showing it going there, and it seems to be running

Both exe's are in the same folder
