Code style when using underscore in php

code-style-when-using-underscore.md

• I am using the php underscore
• Use closures and assign them to variables
• Put variables at begin of the function, main code will after ////////
• Must be

function sumPrice($items) {
  $sum = function ($memo, $item) {
    return $memo + $item['price'];
  }
  
  /////////
  
  return Underscore::from($items)->reduce($sum, 0)->value();
}

• Don't

function sumPrice($items) {
  return Underscore::from($items)->reduce(function ($memo, $item) {
    return $memo + $item['price'];
  }, 0)->value();
}
