execute application problem

[DigitalExpl0it]

Im trying to execute a .exe file using php. Now It executes the application but it just sits there. Is there a way to force php to execute it and then timeout or somthing?

code:

<?
function form() {
?>
<form name="login" action="index.php" method="post">

  <table width="278" border="0" align="center" cellpadding="0" cellspacing="1">
  <tr align="left" valign="top"> 
    <td width="115" bgcolor="#AEC7D9"><strong><font color="#FFFFFF" size="2" face="Arial, Helvetica, sans-serif">&nbsp;&nbsp;Local 
      Port</font></strong></td>
    <td width="160" bgcolor="#DCE7EF"> 
      <input name="lport" type="text" id="lport" size="6">
      </td>
  </tr>
  <tr align="left" valign="top"> 
    <td bgcolor="#AEC7D9"><strong><font color="#FFFFFF" size="2" face="Arial, Helvetica, sans-serif">&nbsp;&nbsp;Remote 
      IP</font></strong></td>
    <td bgcolor="#DCE7EF"> 
      <input name="rip" type="text" id="rip" value="0.0.0.0" size="15"></td>
  </tr>
  <tr align="left" valign="top"> 
    <td bgcolor="#AEC7D9"><strong><font color="#FFFFFF" size="2" face="Arial, Helvetica, sans-serif">&nbsp;&nbsp;Remote 
      Port</font></strong></td>
    <td bgcolor="#DCE7EF"> 
      <input name="rport" type="text" id="rport" size="6"></td>
  </tr>
  <tr align="center" bgcolor="#AEC7D9"> 
    <td colspan="2"> 
      <input type="submit" name="Submit" value="Submit">
      <input type="reset" name="Submit2" value="Reset">
    </td>
  </tr>
</table></form>
<?
}
if ($_REQUEST[Submit] == "Submit") {
	if ($_REQUEST[rip] == "" or $_REQUEST[rip] == "0.0.0.0") {
		echo "<center>IP is wrong!</center><br>";
		//Show Form if somthing is wrong
		form();
	} else {
		//Show All Requests
		echo "Starting Local Port on: ".$_REQUEST[lport]."<br>";
		echo "Starting Remote IP on: ".$_REQUEST[rip]."<br>";
		echo "Starting Remote Port on: ".$_REQUEST[rport]."<br>";
		echo "Starting Port mapper...<br><br>";
		echo "You may now close or stop the web browser.";
	    sleep(5); //Does not help with displaying with the above ^^^
		//Execute program
		exec("pm.exe ".$_REQUEST[lport]." ".$_REQUEST[rip]." ".$_REQUEST[rport]);
	}
} else {
	form();
}
?>

Now this software once ran will always run until manual closed. Its not a standard application. This routes ip's and ports so its always running once ran. Could this be the problem?

Oh if it is, is there a way to echo out the stats before it executes, the following above doesnt echo out.

You could try to use shell_exec() which takes out the output as a variable. You can use this function if it echos the same things that you are trying to echo.

$var=shell_exec("pm.exe ".$_REQUEST[lport]." ".$_REQUEST[rip]." ".$_REQUEST[rport]);

for ($i=0; $i<count($var); $i++)
echo nl2br($var[$i]); // This changes the newlines to <br>'s

Ok, I just read your post again 🙂
Your problem definetly is because of the programs nature(its always on). One solution would be that you make a shell-script that starts the program and when its done, kills the process after.

humm might work....

If I can some how just make it show this

       echo "Starting Local Port on: ".$_REQUEST[lport]."<br>";

    echo "Starting Remote IP on: ".$_REQUEST[rip]."<br>";

    echo "Starting Remote Port on: ".$_REQUEST[rport]."<br>";

    echo "Starting Port mapper...<br><br>";

    echo "You may now close or stop the web browser.";

then run the app I can just hit the stop button on the browser.. but I would need the echo's if thats possible

[cahva]

Well... I didnt mean it like that. If you stop the browser it doesnt echo anything that PHP parses. Thats because the script never gets done(because your program is running).

Sorry I dont have a solution. I can only say that you find some other program that does the same job, but exits when done. Only then PHP can continue the script to end.
