[RESOLVED] Problem outputting to a txt file

[mAGOO]

Hi all,

I'm trying to output all the variables sent to a form to a txt file. As I want all the variables sent and I don't know all the variables being sent I thought that I would catch them in a txt file. I have to use a txt file as the variables are coming from 3rd party software directly and no web page is ever opened.

The code I'm using is:
Also included are the variables I know of

<?php 
$variables = print_r($_REQUEST);

$pilot = $_GET['pilot'];
$date = $_GET['date'];
$time = $_GET['time'];
$callsign = $_GET['callsign'];
$reg = $_GET['reg'];
$origin = $_GET['origin'];
$dest = $_GET['dest'];
$equipment = $_GET['equipment'];
$fuel = $_GET['fuel'];
$duration = $_GET['duration'];
$distance = $_GET['distance'];
$rep_url = "Dummy";
$more = $_GET['more'];
$fsacars_log = $_GET['log']; 


// use ini from pilot folder and append PilotNumber & variable to end EOF
$filereal_name = 'vars.txt';
$somecontent = $variables . $pilots . $time . $date  ; 
$fileneeded = "<a href=http://www.mydomian.com/fsacars";

if (is_writable($filereal_name)) {
   if (!$handle = fopen($filereal_name, 'a')) {
         echo "Cannot open file ($filereal_name)";
         exit;
   }

   if (fwrite($handle, $somecontent) === FALSE) {
       echo "Cannot write to file ($filereal_name)";
       exit;
   }
   echo "Please download your ini file for: $fileneeded/$filereal_name> $newUser</a><br>";


   fclose($handle);

} else {
   echo "The file $filereal_name is not writable";
}
?>

Where I'm having a problem is the "$variables = print_r($_REQUEST);" the other variables work fine and output OK. But I'm more interested in getting the unknown variables to the txt file. After all, the whole point of me doing this is to find all the variables.

The variables are coming from 3rd party software which submits a report to a php file on the server. The variable names are not clearly defined in the help doc so I thought by catching them this way, it would do the trick.

So can anyone see where I've gone wrong? If you can help that would be great.

Thanks

Steph.

PS. I've only just started using php a week or so ago, so be easy on me. 😕

Does this mean that what I'm trying to do can't be done? You can only view variables on page and can't pass them into a txt file?

That should work. Try echo'ing $variables and see what it prints out, then post that output here.

That's the problem though, I can't output it to screen as FSACARS sends data directly from software. I tested this catch page via a quick form I did and it worked fine. All the variables printed to screen. But when it comes to trying to send the output to a txt file, I just get "Array" sent to the txt file. That occures even with the use of the form I made for testing.

In the code above I also put some known variables to test if it was able to send the data and it does.

So the

$variables = print_r($_REQUEST);

gives me variables when I send it to screen, but when I try to use that to send it to a txt file, it only outputs the word "Array" in the txt file.

Cheers

in order for print_r to return a value to a variable you will need to set its second (optional perameter) to true, otherwise it just prints.

eg;

$variables = print_r($_REQUEST,true);

Great! that did the trick.

Thanks for that.
