How to repeat an array in PHP?

Question

$arr = array('1st', '1st');

The above $arr has 2 items , I want to repeat $arr so that it's populated with 4 items

Is there a single call in PHP?

Answer 1

array_fill function should help:

array array_fill ( int $start_index, int $num, mixed $value )

Fills an array with num entries of the value of the value parameter, keys starting at the start_index parameter.

In your case code will look like:

$arr = array_fill(0, 4, '1st');

Answer 2

$arr = array('1st', '1st');

$arr = array_merge($arr, $arr);
