function array_fill (start_index, num, mixed_val) {
  // From: http://phpjs.org/functions
  // +   original by: Kevin van Zonneveld (http://kevin.vanzonneveld.net)
  // +   improved by: Waldo Malqui Silva
  // *     example 1: array_fill(5, 6, 'banana');
  // *     returns 1: { 5: 'banana', 6: 'banana', 7: 'banana', 8: 'banana', 9: 'banana', 10: 'banana' }
  var key, tmp_arr = {};

Please note that php.js uses JavaScript objects as substitutes for PHP arrays, they are 
the closest match to this hashtable-like data structure. 

Please also note that php.js offers community built functions and goes by the 
[McDonald's Theory](https://medium.com/what-i-learned-building/9216e1c9da7d). We'll put online 
functions that are far from perfect, in the hopes to spark better contributions. 
Do you have one? Then please just:

### Example 1
This code
{% codeblock lang:js example %}
array_fill(5, 6, 'banana');
{% endcodeblock %}

Should return
{% codeblock lang:js returns %}
{ 5: 'banana', 6: 'banana', 7: 'banana', 8: 'banana', 9: 'banana', 10: 'banana' }
{% endcodeblock %}
