One Line Template Engine

A One Line Template Engine in PHP

This is a really clever example of using a single line of PHP to fill in a HTML template and output a web page.

I found the original in the forums at http://www.webmasterworld.com/.

The one line engine --

print preg_replace("/\{([^\{]{1,100}?)\}/e","$$1",file_get_contents("template.tpl"));

It works by finding any string starting with an opening brace and ending with a closing brace and substituting the php variable with the same name.

An example of the template file -- template.tpl -- as used for this example.

<html> <head> <title>{title}</title> </head> <body> <h1>{header}</h1> {text} </body> </html>

This template has three variables defined -- {title}, {header}, and {text}.

Using the template engine in its simpliest form.

$title="The One Line Template Engine Example"; $header="See this Example Work."; $text="Magically all the placeholders are replaced!"; print preg_replace("/\{([^\{]{1,100}?)\}/e","$$1",file_get_contents("template.tpl"));

Elegantly simple?
