[SOLVED] Trouble outputting a variable?

[galvin]

I'm probably not explaining this will, so I'll apologize ahead of time.  Anway, I have a page that echos the following code (contained in $userRow) over and over for each User...

 

$userRow = "<tr><td class=\"name\">{$users["firstname"]}" . " " . "{$users["lastname"]}<br/><img src=\"http://gdoot.com/gsfl/images/user_{$users["userid"]}.jpg\" /> <span class=\"record\">RecordPlaceHolder</span><span></span></td>";

 

In that last empty span, I want it to display a certain number for each user.  Earlier in the code on the same page, I have a variable for each user to hold that number, such as..

 

$numberforuser_1 = 2

$numberforuser_2 = 4

$numberforuser_3 = 1

$numberforuser_4 = 4

$numberforuser_5 = 0

$numberforuser_6 = 2

 

And so on.

 

I have each user's ID (and first name and last name) stored in the $users array.  So in that last empty SPAN, I assumed I could put "<span>$numberforuser_{$users["userid"]}</span>" and I would think for each User it would output $numberforuser_X and therefore, if, for example, it was "$numberforuser5," it would output "0" in that SPAN since above, $numberforeuser_5 = 0.

 

But it's not doing that.  It seems like it won't let you call something first to get PART of a variable and then have that varible's value actually output.

 

I'm using the same thinking as you can see earlier that has "http://gdoot.com/gsfl/images/user_{$users["userid"]}.jpg" and that pulls in each user's ID fine and displays the proper image.  But since I'm putting a VARIABLE instead of a URL, it's not working.

 

Assuming that makes sense, which it probably doesn't, anyone know what I'm doing wrong, or another way to do this?

I'm a little lost, so this may get you lost... so possibly just ignore me.

$numberforuser[1] = 2

$numberforuser[2] = 4

$numberforuser[3] = 1

...

use $numberforuser[$users["userid"]]

 

but I really am lost on what you are looking for exactly

[trq]

${'numberforuser_' . $users["userid"]}

Your format worked perfectly, Thorpe!  Thanks to you both for helping me!

I'll let you know though that using variable variables (my method) is far slower and IMO harder to read than simply using an array (Brian W's method).
