title: PHP PDO throwing syntax error, need feedback
body: <p>I need a little feedback on why the following is throwing a SYNTAX error of : "unexpected '[', expecting ')'" , it would be the second line in the code below:</p>
  
  <pre><code>if($deleteBeforeInsertFieldKey!==false){
      if($deleteQry-&gt;execute([$deleteBeforeInsertFieldKey=&gt;$row[$deleteBeforeInsertFieldKey]])===false){
          throw new \Exception('There was a problem deleting a row prior to insert.');
      }
  }
  </code></pre>
