PHP Script Checking with CSE HTML Validator
CSE HTML Validator Standard and above can integrate with PHP's syntax checker for easy PHP script syntax checking. Simply download & install PHP and then point CSE HTML Validator to it.
You can also use CSE HTML Validator to check the HTML output of your PHP scripts.
Download CSE HTML Validator Standard or above and install (the free trial will work).
Download the PHP Windows binary files (not the source). We recommend downloading the ZIP file and then extracting it to a folder like c:\PHP or C:\Program Files\PHP\php.exe. Either the "thread safe" or "non thread safe" download options should work.
Load CSE HTML Validator and go to Options->Validator Engine Options and the PHP Checker Page. Make sure the option to enable PHP syntax messages is checked, and the path to php.exe is set correctly to something like C:\PHP\php.exe.
In CSE HTML Validator, load your PHP document (or HTML, CSS, etc) and press F6 to check it. The results should appear in the Results Window at the bottom of the window.
You can also use the integrated web browser (in browse mode) to check the HTML output of PHP scripts.
