title: How to run my php file from mac terminal
body: <p>Sorry if this is a very novice question - I am a novice - but, I have no clue how to run my php file from the terminal.</p>
  
  <p>I type in the mac terminal something like this: php test.php (where test.php is the file i'm trying to run)
  Then, I get this: Could not open input file: test.php</p>
  
  <p>I think I'm having this problem because I didn't change the directory (not sure how to do that either).</p>
