Question

Say I have an array:

$myArray = array("foo", "bar");

What is a good way to repeat the values in the array onto the end of the array so that:

$myArray = array("foo", "bar", "foo", "bar");

I thought maybe array_push would work like this:

array_push($myArray, $myArray);

but that actually pushes the array object and not the values of the array.

Answer 1

you can do this with array_merge

$tmp = $myArray;

$myArray = array_merge($myArray, $tmp);

This will rely on you not worry about the array keys..

Another solution would be:

$tmp = $myArray;
foreach($tmp as $val) {
    $myArray[] = $val;
}
