title: PHP arrays -- square brackets vs curly braces ($array[$i] vs $array{$i})
body: <p>As i recently learned <code>$myArray[$index]</code> in PHP is equivalent to <code>$myArray{$index}</code>.</p>
  
  <p>This mentioned on <a href="http://php.net/manual/en/language.types.array.php" rel="noreferrer">PHP docs</a>. Also i found small discussion here: <a href="https://stackoverflow.com/questions/8092248/php-curly-braces-in-array-notation">PHP curly braces in array notation</a>.</p>
  
  <p><a href="http://www.php-fig.org/" rel="noreferrer">PHP-FIG</a> does not contains any recommendations about which way is preferable. </p>
  
  <p>So, my question is -- it's just a matter of taste or may be some objective reasons to use one or the other syntax?</p>
