## Description

``bool show_source` (string filename)`

The show_source() function prints out a syntax higlighted version of the code contained in `filename` using the colors defined in the built-in syntax highlighter for PHP. It returns `TRUE` on success, `FALSE` otherwise (PHP 4).

This function is an alias for the function highlight_file()
