The PHP filter module adds a PHP filter to your site, for use with <a href="@filter">text formats</a>. This filter adds the ability to execute PHP code in any text field that uses a text format (such as the body of a content item or the text of a comment). <a href="@php-net">PHP</a> is a general-purpose scripting language widely-used for web development, and is the language with which Drupal has been developed. For more information, see the online handbook entry for the <a href="@php">PHP filter module</a>.
