PHP popen Help

[muazzamazaz]

I have the following code but did't extract the required information.

<?php
$macdata = '10ca501574998b01bac2573de1284221';

$handle = popen('./cgi-bin/irisreg check '.$macdata, 'r');
$read = fread($handle, 2096);
  pclose($handle);
if($read != 'ok')
{
	$result = $handle.'Invalid or Corrupt Machine Data';
}
else
{
	$handle = popen('./cgi-bin/irisreg prodid '.$macdata, 'r');
	$inprodid = fread($handle, 2096);
	pclose($handle);
	$handle = popen('./cgi-bin/irisreg macid '.$macdata, 'r');
	$inmacid = fread($handle, 2096);
	pclose($handle);
}
?>

Here product id should be like 61c20d (not exactly but similar characters.

$macdata = '28abe813e3a41c47a8cc33043cf3f6eb9118924ad985641706c994b5f1db38f2';
ProdId should be for this: 61cd6219

Welcome to PHPBuilder. When posting PHP code, please use the board's [noparse]

..

[/noparse] bbcode tags as they make your code much easier to read and analyze.

As for your issue... what is happening instead? Are you getting any error messages? Do you have display_errors set to On and error_reporting set to E_ALL (or better)?

I am getting Resource Id 2 in $handle variable while it should show required extracted data.

[NogDog]

$handle will be a resource ID. To read the result, you'll need to use something like fread(), using $handle as the 1st parameter.

[muazzamazaz]

Already using it.

[bradgrafelman]

$handle will still be a resource after using the appropriate function.

[NogDog]

$result = [B][COLOR="#800080"]$read[/COLOR][/B].'Invalid or Corrupt Machine Data'; 

[muazzamazaz]

Nothing show in $read.

[bradgrafelman]

Here are a few suggestions to try to get a bit more information about what's happening:

    echo "./cgi-bin/irisreg is:" . (is_executable("./cgi-bin/irisreg") ? "" : " NOT") . " executable<br>\n";
    $handle = popen("./cgi-bin/irisreg check $macdata 2>&1", 'r'); 
    $read = fread($handle, 2096); 
      pclose($handle); 
    if($read != 'ok') 
    { 
        var_dump($read);
        $result = 'Invalid or Corrupt Machine Data'; 
    }

The above modifications should help confirm the following:

1. "./cgi_bin/irisreg" exists and is executable by the PHP process.

2. No errors are being produced by the 'irisreg' program (which might only be output on STDERR, hence the '2>&1' redirection).

3. The response ($read) truly is empty.

Got this:

cgi-bin/irisreg is: NOT executable<br> string(96) "'cgi-bin' is not recognized as an internal or external command, operable program or batch file. " Invalid or Corrupt Machine Data

Ah, Windows. There you go.

Since popen contains an entire command line and not just a file path, it can't just convert [font=monospace]/[/font] to Windows-style [font=monospace][/font] directory separators. ("[font=monospace]dir/s[/font]" is a recursive directory listing, not a relative path to a file named "[font=monospace]s[/font]" in a directory named "[font=monospace]dir[/font]".)

Consider using [font=monospace]\[/font] (doubled because of [font=monospace][/font]'s use as an escape character) instead, or (perhaps better) using [man]realpath[/man] to normalise the path (not the entire command line).

[muazzamazaz]

tried but same result.
