So I have a variable which I explode:
$values = explode ('|', $split);
This can contain any number of values from 1 to 10+
I have another big array let's call it $tree. I need to loop round the $values whilst building up an array based on the $tree variable.
E.g:
$newArray = $tree [$values [0]][$values [1]];
But this needs to be done dynamically based on the number of elements in the $values array.
Any ideas?
Is this what you're trying to do?
$newArray = array();
foreach($values as $key => $val)
{
$newArray[] = $tree[$val][$values[$key + 1]];
}
You need a foreach loop that goes to every single value you have and then put them in the $tree array something like:
$newArray = array();
foreach($values as $index => $value)
{
$newArray[] = $tree[$value][$value[$index + 1]];
}
create a temporary array from $tree and iterate through the values getting each index:
$result = $tree;
foreach ($values as $val){
$result = $result[$val];
}
This way you go down one level deeper into $tree with each value supplied in $values, and $result holds the value stored in $tree at the point you have reached. For example if you have a navigation tree, $values would be the "breadcrumb" of the current navigation position, and $result is the remaining tree from this point downwards.
I think this is what you want. It goes through pairs of elements of $values, using them as the indexes into $tree to add to $newArray
$newArray = array();
for ($i = 0; $i < count(values); $i += 2) {
$newArray[] = $tree[$values[$i]][$values[$i+1]];
}
$values=array(0, 1, 3);
$tree=array("First", "Second", "Third", "Fourth");
$newarray=array();
for ($i=0; $i<count($values); $i++)
{
$newarray[]=$tree[$values[$i]];
}
echo(implode($newarray,", "));
Something like that what you were looking for?
foreachis not enough?
