this is my first post to the PHP general list.
I have an issue with a variable variable
(http://php.net/manual/en/language.variables.variable.php)
My use case:
I have an array called $myArray. The structure is as following:
array(1) {
["user_interface"]=>
array(1) {
["design"]=>
array(1) {
[“my_colors"]=>
array(5) {
["item_number_one"]=>
string(6) "red"
["item_number_two"]=>
string(40)
'["user_interface"]["design"]["my_colors"]["item_number_one"]'
}
}
}
}
As you can see, the item_number_one has no direct color value assigned but the
structure of the path to item_number_one in the $myArray variable. I tried with
array_wal_resursive. During this step (the array building is completed) I want
to find these values (I use a static value in my example, in the real code I
will use regular expressions) and assign the value of the virtually related
item to the considered item.
So in my example above, I want to have the following values after the process
is done:
$myArray[user_interface][design][my_colors][item_mumber_one] = red; // this is
item number 1
$myArray[user_interface][design][my_colors][item_mumber_two] = red; // this
should be item number 2
The second issue here is, how do I evaluate at which point the process is
exactly, because the value and the key that is transferred to the function by
array_walk_recursive has only the value itself but not array path to the
current item.
Any idea how get this done? Or am I too complicated maybe?
I tried several combinations of ${$var}, $myArray{$var}, {$myArray}{$var} ...
and many more.
Any help is much much appreciated!
Cheers, Nils
I'm short of time to conjure this in detail; but, on the surface it seems like
nested foreach()s would do the trick.
foreach($myArray as $key1 => $userArray)
{
foreach($userArray as $key2 => $designArray)
{
foreach($designArray as $key3 => $colorsArray)
{
foreach($colorsArray as $key4=>$itemsArray){
//do stuff here. All keys are available
}
}
}
}
}
