Running php index.php as shell in webpage
so i have a bit of a unique situation.

i have an encrypted index.php file that that can't be run the normal way that a web browser would run it. if it is run the normal way, the php script will show only gibberish on the web browser, instead of the actual php code.

when run from the command line, the php code works as it should:

Code:
root@jbow-VirtualBox:~# time php $(./index.php)
PHP Warning:  require(/home/jbow/../bootstrap/autoload.php): failed to open stream: No such file or directory in - on line 22
PHP Fatal error:  require(): Failed opening required '/home/jbow/../bootstrap/autoload.php' (include_path='.:/usr/share/php:/usr/share/pear') in - on line 22

my question is, is there a way to get web browsers to run the index.php through a shell, as im doing in the preceding example? is there a php setting i can modify that'll let web browsers know how to run php scripts for a particular web page/site?

Thank you

Without seeing the code, we can only speculate why it doesn't work.

This seems to get rid of the encrypted data from being shown on the webpage. however, it still doesn't show the content of the executed command.

so in other words, how do i get php to show on the web page the output of a command?

Code:
<?php exec('/var/encrypted/banana.php'); ?>


i have a php page that only has the above code in it. what i want to do is, when the banana.php script is executed, i want the output shown on the php page.

You may try something like this

Test script
PHP Code:
[akshay@localhost tmp]$ cat test.php 
<?php
    for ($h = 0; $h < 10; $h++) 
    {
    echo "<p>Line Number $h</p>".PHP_EOL;
    }
?>
This is what you execute on your browser
PHP Code:
[akshay@localhost tmp]$ cat index.php 
<?php

// execute like this
exec("php /tmp/test.php 2>&1", $out, $return);

// Show content on browser
echo implode(PHP_EOL, $out ).PHP_EOL;

exec("ps aux | head -10 2>&1", $out1, $return);

// Show content on browser
echo '<pre>'.implode(PHP_EOL, $out1 ).'</pre>';
?>
Output
PHP Code:
[akshay@localhost tmp]$ php index.php 
<p>Line Number 0</p>
<p>Line Number 1</p>
<p>Line Number 2</p>
<p>Line Number 3</p>
<p>Line Number 4</p>
<p>Line Number 5</p>
<p>Line Number 6</p>
<p>Line Number 7</p>
<p>Line Number 8</p>
<p>Line Number 9</p>

Thanks a million!! This works!

Suppose the "testscript" in your example is a form that accepts input from a user. how does the php script which the browser reads interpret that?

PHP Code:
<?php
// in your index.php

$get=escapeshellarg(serialize($_GET));
$post=escapeshellarg(serialize($_POST));

// execute like this
exec("php /tmp/test.php  '$get'  '$post' 2>&1", $out, $return);


?>
PHP Code:
<?php
// In your script

$get_array = unserialize($argv[1]);

$post_array = unserialize($argv[2]);
?>

It may be difficult for you to rewrite code for form and user management for example file upload,session,cookie etc, if you can explain your aim, there can be some simple solution for the same.
