title: PHP call a function from a function
body: <p>What's the PHP code that would do one thing first and then take that and do a second.</p>
  
  <p>1st: I want $_GET a variable and then run a query on it and return variables.</p>
  
  <p>AND THEN</p>
  
  <p>2nd: Use those "other" variables in a query.</p>
  
  <p>I'm thinking I want to do this with two functions b/c my query is based off of what values I send from a form.  So it has to get the values from the url and then run the query.</p>
