Convert PHP array_fill() to Ruby | PHP to Ruby

array_fill

Posted on October 13th, 2010 RubyLove 1 comment

The array_fill() function in PHP allows an array to be populated (i.e. filled) with a particular value.

PHP
```
$a = array_fill(3, 5, 'php');
print_r($a);
/*
Array (
	[3] => php
	[4] => php
	[5] => php
	[6] => php
	[7] => php
)
*/
```
In Ruby this is not really possible because Ruby arrays must have their keys filled in the correct order, i.e. you cant skip assigning values to keys in a Ruby array. As such, the next best thing is to fill those values with nil, or use a hash instead.

Ruby
```
a = [nil] * 3 + ['php'] * 5;
puts a;
# => [nil, nil, nil, 'php', 'php', 'php', 'php', 'php']
```

  With a hash
  
  a = {}
  5.times{|i| a[i+3] = ‘php’}
  puts a
  # => {3=>”php”, 4=>”php”, 5=>”php”, 6=>”php”, 7=>”php”}
