You can set up php.exe as "compiler" for php files (or for html files) in Highlighter settings. Enter path to php.exe as compiler, "%File%" as parameter, check "catch output", enter "*in %F on line %L" for the log parser. The log window at the bottom of the PSPad window then shows php.exe's output, including errors msgs. Double-clicking the error line in the log window takes you to the line of code in the main window where the error occurred. For reformatting html code, there is an integration with html tidy. But I haven't found a good php beautifier yet. (Somebody else, maybe?)
