Cannot find PHP type in Data Format I am new to Drupal and using Drupal7.23 in windows7 with XAMPP installed. While I am creating any content I cannot find "PHP type" in the Data Formats. Kindly tell how to add PHP type in Data Format, as I need to add PHP to the content.
Enable the 'PHP Filter' module available in drupal core:

Go to modules list: /admin/modules and than in Core you will find PHP filter module as indicated below, so just enable it.
