I have the following array:
$myArray = array(0=>'Zero',
1=>'One',
2=>'Two',
3=>'Three',
4=>'Four');
And i would like it in the following format:
$newArray = array('One'=>
array('Two'=>
array('three'=>
array('four'=>
array('five'=>
array())))));
This could be infinite levels although more realistically about 1-6 levels deep.
Something like this should do:
$myArray = array(0=>'Zero',
1=>'One',
2=>'Two',
3=>'Three',
4=>'Four');
$myRecursiveArray = array();
$l = count($myArray);
for($i = $l; 0 < $i; --$i)
{
$myRecursiveArray = array($myArray[$i - 1]=> $myRecursiveArray);
}
yes123 has a shorter answer, but it leaves a reference in your array. Could have no impact if it's what you need.
Sorted it this morning, aparently the answer was sleep!
heres my solution
$myNewArray = array();
$myArray = explode('->',"Zero->One->Two->Three");
$myArray = array_reverse($myArray);
foreach($myArray as $key => $value) {
$myTempArray = $myNewArray;
unset($myNewArray);
$myNewArray[$value] = $myTempArray;
}
Thanks for the answers, comments on my solution are welcome =)
$newArray=array();
$current = &$newArray;
foreach($myArray as $v) {
$current[$v] = array();
$current = &$current[$v];
}
