PHP is pissing me off!

[TheFilmGod]

while ($i > 0 ){

			$field = "a . $i";
			${$field} = $row_data['$field'];
			$i--;

		}

 

This is what I'm trying to achieve. I found the problem to come from this:

 

$test = a31;
$hello = $row_data['$test']

What problem would that be?

 

What is actually going wrong with it, does it display any errors?

 

Give us something to work with.

When I echo the variable, nothing is displayed.

Can you post all the code and any output.

I see 5 variables there.  You really need to provide more info on what the problem is.

Ive no idea what your trying to do because you havent explained yourself at all. However, one problem with your code is that variables are not interpolated within single quotes.

 

You might try....

 

<?php

$i = 3;

while ($i > 0 ) {
  $field = 'a' . $i;
  ${$field} = $row_data[$field]; // you do not need quotes around $field
  $i--;
}

echo $a3."\n";
echo $a2."\n";
echo $a1."\n";

?>

 

Does this help at all? Otherwise, we need more help from you explaining your issue.
