vTemplate is a php template solution which is packed with features that you'll need to succesfully and efficiently split your coding from your design. It supports multiple nested loops, nested if statements, template includes and formatting of the variables from the templates.
You can also extend vTemplate by using the powerful vTemplateCache class which writes the compiled template file to disk with massive performance gains and also vTemplateDebug, a helpful module for finding out where you're going wrong.
