C to Module?

[rab]

Alright I have a certin peice of C code that is hard to port. I was wondering if there was a safe way of executing it and rettrieving information from it or compiling it as a php module. Is there any way to do this?

[Barand]

Have a look at

[a href=\"http://us3.php.net/exec\" target=\"_blank\"]http://us3.php.net/exec[/a]

[rab]

The out put of the program is
[code]
69.164.100.200   5150
    83.71.83.19   56129
   24.14.144.22   1401
   70.125.156.6   5150
  24.33.131.239   5150
206.174.154.174   5150
  70.20.233.160   50206
   24.55.91.108   5150
   24.86.86.200   62841
  24.15.190.153   5150
  70.50.128.152   63630
     72.81.9.43   5150
   65.2.139.121   50108
   12.219.67.24   32929
  68.11.123.247   60542
81.164.109.163   5150
69.192.166.103   63553
   4.225.34.193   5150
   68.47.43.164   5150
  71.234.75.198   62015
65.175.251.198   5150
24.131.247.197   5150
  172.149.37.31   5150
  68.197.169.86   5150
  66.245.63.108   12417
[/code]

I need to parse through that for a specific IP how would I do this.

Note I tried exec, system, passthru and non of them return this.

Try this Rab,

[code]
<?php
$string = " 69.164.100.200   5150
    83.71.83.19   56129
   24.14.144.22   1401

/* The IP we want to find */

?>
[/code]

That is assuming you can get the output of the program into a string in php

[rab]

Finding it wont be a problem, getting the return into a string is.

[Barand]

If you run your C program from the command prompt, does it returm the output to the screen?

In other words, does it write to the stdout stream?

[rab]

Yes it does

EDIT::::

popen gives me Resource id #2.

Now how should i get the IP's and Ports from it? or is there a better way to do this.

[Barand]

try
[code]$command = 'dir *.php';
$arr = array();
$res = ex_ec($command, $arr);   // remove _ from ex_ec

  // check output in $arr
echo '<pre>', print_r($arr, true), '</pre>';[/code]

To quote one of your earlier posts..

"I need to parse through that for a specific IP how would I do this."

*shrug*

[rab]

worded bad, sorry. :/

[rab]

Now my question is, when i let users enter things, like IP's , how can i stop them from doing things they are supossed to. Example, if they enter "124.35.64.23; wget netcat; ./netcat", that will download netcat and execute it. How can i stop things like that.

Use this and/or regular expression functions (ereg/preg):
