shell_exec do not list whole output

[blagojkk]

In the browser when I open the file I  need to see the output of the ifconfig linux command on the server.

 

This is the index.php

 

<?

$iplist = shell_exec("ifconfig");

print "<pre>$iplist</pre>";

?>

 

but when I open the index.php in a browser I can see only the first couple of lines, nothing more. Can someone help me what to do?

 

The strange thing is when I run the index.php from the command line with "php index.html" it shows the correct result.

 

Any help..?

 

Thanks,

I just ran it locally, and due to the way it lists the interface type specifications, I had to add htmlentities() to get it to display properly. Try it this way:

 

<?php
$iplist = shell_exec("ifconfig");
print "<pre>" . htmlentities($iplist) . "</pre>";
?>

Still the same. It is not the problem how the output it is list, it is the problem that the list/output it is not complete. On other machine I have it works without a problem, but both machines have exactly same OS, apache and php version etc... Completely identical.

Load it in the browser and do a "View Source" to see if something in the output is causing the browser to cut off the output to the screen.

I get this:

I think it is a problem with php itself. I have 3 servers, on 1 of them it is working without a problem, on other 2 don't, but I can not figure out what is the difference because they are completely identical.

[Pikachu2000]

So that output is different than what you get if you issue ifconfig at a command line? That's weird.

coincidence !!... I've been working in the same problem/behavior with a testing code for more than 1 hour and I've been having exactly the same issue... output from exec(), shell_exec(), passthru() are truncated.

 

Test machine is WXP with Apache/PHP/MYSQL ... weird..

Problem solved. It was apache server side permission problem.

[mikosiko]

could you share the solution in your case?
