title: str_getcsv example
body: <p>I want to parse a comma separated value string into an array. I want to try the <code>str_getcsv()</code> php function but I can't find any good examples on how to use it. </p>
  
  <p>For example I have an input where users submit tags for programming languages (php, js, jquery, etc), like the "tags" input in stackoverflow when you submit a question.</p>
  
  <p>How would I turn an input with example <code>value="php, js, jquery"</code> into an array using str_getcsv?</p>
