The Markdown PHP Extension provides a wrapper to the Discount markdown library.

To compile your new extension, you will have to execute the following steps:

phpize
./configure [--with-discount]
make
sudo make install

You can now load the extension using a php.ini directive

extension="discount.so"

or load it at runtime using the dl() function

dl("discount.so");

The extension should now be available, you can test this using the extension_loaded() function:

if(extension_loaded("discount")){
  echo "discount loaded :)";
}else{
  echo "something is wrong :(";
}

The extension will also add its own block to the output of phpinfo();

Implementation details have been taken from:

• php-discount by Gustavo Lopes, but replaced the bundled discount library with a shared one. [https://github.com/cataphract/php-discount]
