Dynamic variable names in PHP

August 18th, 2009 No comments

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....
