2848 | PHP Markdown Extra
2849 | ==================
2850 |
2851 | Description
2852 | -----------
2853 |
2854 | This is a PHP port of the original Markdown formatter written in Perl
2855 | by John Gruber. This special "Extra" version of PHP Markdown features
2856 | further enhancements to the syntax for making additional constructs
2857 | such as tables and definition list.
2858 |
2859 | Markdown is a text-to-HTML filter; it translates an easy-to-read /
2860 | easy-to-write structured text format into HTML. Markdown's text format
2861 | is most similar to that of plain text email, and supports features such
2862 | as headers, *emphasis*, code blocks, blockquotes, and links.
2863 |
2864 | Markdown's syntax is designed not as a generic markup language, but
2865 | specifically to serve as a front-end to (X)HTML. You can use span-level
2866 | HTML tags anywhere in a Markdown document, and you can use block level
2867 | HTML tags (like and as well).
2868 |
2869 | For more information about Markdown's syntax, see:
2870 |
2871 |
2880 |
2881 | Please include with your report: (1) the example input; (2) the output you
2882 | expected; (3) the output Markdown actually produced.
2883 |
