Duplicate Array Contents Help

Hi All

I have an array created dynamically:

array (
[0] = Value 1
[1] = Value 2
[2] = Value 3
[3] = Value 4
[4] = Value 5
)

Now it might seem a silly but I need to duplicate the values in that array X number of times before I parse it in my code so it might look like:

array (
[0] = Value 1
[1] = Value 2
[2] = Value 3
[3] = Value 4
[4] = Value 5
[5] = Value 1
[6] = Value 2
[7] = Value 3
[8] = Value 4
[9] = Value 5
[10] = Value 1
[11] = Value 2
[12] = Value 3
[13] = Value 4
[14] = Value 5
)

What is the best/quickest way to do that?

Thanks in advanced.

You could use array_merge:

<pre><?php
$array = array(
   'value1',
   'value2',
   'value3'
);
$array = array_merge($array, $array, $array);
print_r($array);
?></pre>

Just to be fancy, you could also do something like the following in case the number of times you want the array to be repeated is variable:

$array = array(
   'value1',
   'value2',
   'value3'
);

$num_times = 5; // hard-coded example

for($params = array(), $i = 1; $i <= $num_times; $i++)
  $params[] = $array;

$array = call_user_func_array('array_merge', $params);
