Creating Dynamic Variables

[meshhat]

Hello,

 

I'll start by saying I'm a complete newbie to php.  I think what I want to do is fairly simple, though.

 

I'm trying to pass 100 variables (named gain1, gain2...gain100) from a swf to a php file then write these variables to a text file.  Sending the data works fine. 

 

I just need help creating the variables in the php file.  Since all the files have partly the same name, I was hoping to create the variables dynamically.  I was hoping to do something like this:

 

$myFileName = "myfile.txt";
$myFileHandle = fopen($myFileName, 'a') or die("can't open file");

for (i=1; i<100; i++) {
$gaintext + i= $_POST['gaintxt1' + i];
fwrite($myFileHandle, $gain + i);
}

 

However, this isn't working obviously.  Any help?

Try this:

for ($i=1; $i<100; $i++) {
  $gaintext=$_POST['gaintxt1'.$i];
  fwrite($myFileHandle, $gaintext);
}

 

I've never grabbed data from a flash file beforeso I've no idea if this will work.

Are these the only variables being posted by the form?

 

<?php

  $myFileName = "myfile.txt";
  $myFileHandle = fopen($myFileName, 'a') or die("can't open file");

  foreach($_POST as $val) {
    fwrite($myFileHandle, $val);
  }

?>

Thanks for the responses.  Actually no, there are 3 variables being passed.  All the same concept though:

 

gain1, gain2, ...gain100

loss1, loss2, ...loss100

net1, net2, ...net100

 

Yesideez, that didn't seem to work.  I'm passing the variables via a POST. The following variables give me the first respective variable:

$gain = $_POST['gain1'];
$net = $_POST['net1'];
$loss = $_POST['loss1'];

 

I just don't want to do this 100 times for each.  thorpe, I'll try your recommendation.

I should have actually asked. Do you want ALL values from the $_POST array written to the file? If so... the above method I posted should work.
