Dynamic variable names in PHP

I'm going to show you how to use dynamic variable names in php. It's quite simple, just put your variable name in between {} symbols.

  1. // declare prefix. In a loop this would probably be a number.
  2. $prefix = "pfx";
  3.  
  4. // build your variable
  5. ${"varname_{$prefix}"} = "success";
  6.  
  7. //This would output "success"
  8. echo $varname_pfx;

Simple isn't it....
