title: Parse error: syntax error, unexpected '–' (T_STRING) in PHP
body: <p>I am getting a Parse error: syntax error, unexpected '–' (T_STRING) in the following line:</p>
  
  <pre><code>$lbm = ((0.407 * $weightkg) + (0.267  * $heightcm) - 19.2) / 0.453592;
  </code></pre>
  
  <p>From what I see, I am using a subtraction sign and not a hyphen. Other than that, I don't know what could be wrong. Anyone know how to fix this?</p>
