Taco HTML Edit Help > Previewing PHP
Taco HTML Edit supports both Preview and Live Preview of PHP documents. For these previews, Taco HTML Edit will process the document with the PHP Command Line Interface, and then use the output for the preview. Taco HTML Edit will search for the PHP Command Line Interface in several common locations, but if PHP previewing is not working, you may need to specify the location in the Preview section of the Preferences.
