In a SPA, PHP returns the initial HTML of the web page to the browser. From that point on your javascript code runs the show. 

• respond to events such as button clicks 
  
• call the XMLHttpRequest API to retrieve JSON formatted data from your PHP web server
  
• render new HTML that merges JSON data and HTML templates
