title: Any reason to disable session functionality in PHP if not being used?
body: <p>Our architecture is such that we handle cookies and sessions internally instead of using the built in PHP functionality.</p>
  
  <p>The PHP documentation states: "Session support is enabled in PHP by default. If you would not like to build your PHP with session support, you should specify the --disable-session option to configure."</p>
  
  <p>My question is, is there any reason to disable it? Does session support add any overhead to an at-scale application if it's enabled but not being used?</p>
  
  <p>Many thanks.</p>
