PHP Question

Run PHP code on local MacOS Jekyll site, port 4000

I've build a Jekyll website on my localhost (MacOS Mavericks). The website is served at http://localhost:4000/website/ and everything regarding Jekyll is running just fine.

However, I now want to have a contact form in PHP that allows me to receive emails. I placed a contact.php file in the website/ folder and have the form POST to that file. On my remote web server, this is working perfectly. However, on the localhost, the PHP isn't parsed, and plain text is displayed on contact.php. However, PHP is parsed perfectly on localhost/contact.php.

How do I get my localhost (Apache? PHP?) to process PHP files on my local Mac http://localhost:4000/ (without breaking my Jekyll website that listens on the same :4000 port)?


You can't use the same port. The port determines the application endpoint that will handle the request on the IP address. The Jekyll server (WEBrick library) uses port 4000 as a default.

The typical way to handle this problem, is to use a "web service" to add dynamic functionality. For instance, the jekyll docs suggest using something like FormKeep, or SimpleForm.

What you're asking is to setup a "web service" yourself. To do this it would need to be on another port or another IP address. The "service" will simply act as an endpoint to accept and process your form post. In this case you could setup a webserver using Apache/PHP on a different port than Jekyll -- such as the standard port 80 -- then write a PHP script (e.g., webform.php) that in combination with the static form is setup to respond and process your form.

Note: It is possible to configure both Jekyll and Apache to respond to requests on port 4000. However, both applications (aka servers) can't be running at the same time. The ip:port combination determines which application an internet request is sent to.
