variable problem yet again

8ride

I am trying to display the variable Title_up1, $Title_up2, etc. The number is generated by a while loop which works fine.
The Problem is, it just displays $Title_up1 instead of actually displaying the string which that variable is representing (declared earlier in the code, not shown).

$count =4;
while ($count > 0) {
	$DispTitle = '$Title_up'.$count;
	$DispAuthor = '$Author_up'.$count;
	$DispDate = '$Date._up'.$count;

echo ("<tr><td >$DispTitle</td><td>$DispAuthor</td><td>$DispDate</td></tr>");

$count = $count - 1;
}

yes.... you're chasing a variable variable you are.

I cant find my earlier post, but here's an example that you should be able to morph into yours...

<?

$var1 = 10;
$var2 = 20;
$var3 = 30;

for($i=1;$i<=3;$i++)
{
    $variable = "var".$i;
    echo $$variable;
}

?>

sorry to not be more help - my dinner's on the table!

Its ok, I was able to solve the problems using arrays instead.

note the single quote takes the string literally while a double quote intrepets the line.
example

$var = "hello world";
echo '$var'; //outputs $var
echo "$var"; //outputs hello world

there is another possible solution for your problem. I think you could use eval().

here are you solutions:

// solution 1
// changed to double quotes
$count =4;
while ($count > 0) {
    $DispTitle = "$Title_up".$count;
    $DispAuthor = "$Author_up".$count;
    $DispDate = "$Date_up".$count;

echo ("<tr><td >$DispTitle</td><td>$DispAuthor</td><td>$DispDate</td></tr>");

$count = $count - 1;
}

//solution 2
// to lazy to try it, but *should* work.
// its my theory.
$count =4;
while ($count > 0) {
    $DispTitle = eval($Title_up.$count);
    $DispAuthor = eval($Author_up.$count);
    $DispDate = eval($Date_up.$count);

echo ("<tr><td >$DispTitle</td><td>$DispAuthor</td><td>$DispDate</td></tr>");

$count = $count - 1;
}

also note that this line:
$DispDate = '$Date._up'.$count;
has a dot after $Date, i'm not sure if you want that there.

edit:
use a for loop, i think its sometimes easier to read
// syntax could be off.
for($count = 1; $count <= 4; $count++){
// same code in while loop
// except for $count = $count - 1;
}
