Combine array into inline output

[Kemut]

How do I combine this array and display an output inline.

 

 

<?php
$array = array(
'0' => array(
'id' => 1,
'name' => 'Sizes',
'parent' => 0,
'children' => array(
'0' => array('id' => 4, 'name' => 'S', 'parent' => 1),
'1' => array('id' => 5, 'name' => 'L', 'parent' => 1),
'2' => array('id' => 6, 'name' => 'M', 'parent' => 1)
)
),
'1' => array(
'id' => 2,
'name' => 'Colors',
'parent' => 0,
'children' => array(
'0' => array('id' => 7, 'name' => 'White', 'parent' => 2),
'1' => array('id' => 8, 'name' => 'Black', 'parent' => 2)
)
),
'2' => array(
'id' => 3,
'name' => 'Types',
'parent' => 0,
'children' => array(
'0' => array('id' => 9, 'name' => 'Polyester', 'parent' => 3),
'1' => array('id' => 10, 'name' => 'Lycra', 'parent' => 3)
)
)
);

 

My desire output should be like this

 

<table>
<tr><td>Sizes, Colors & Types</td></tr>
<tr><td>[s] [White] [Polyester]</td></tr>
<tr><td>[s] [White] [Lycra]</td></tr>
<tr><td>[s] [black] [Polyester]</td></tr>
<tr><td>[s] [black] [Lycra]</td></tr>
<tr><td>[L] [White] [Polyester]</td></tr>
<tr><td>[L] [White] [Lycra]</td></tr>
<tr><td>[L] [black] [Polyester]</td></tr>
<tr><td>[L] [black] [Lycra]</td></tr>
<tr><td>[M] [White] [Polyester]</td></tr>
<tr><td>[M] [White] [Lycra]</td></tr>
<tr><td>[M] [black] [Polyester]</td></tr>
<tr><td>[M] [black] [Lycra]</td></tr>
</table>

 

Let me know how to build the recursive function to display the output

[requinix]

You'd use a recursive function to turn that array into something easier to manage. Recursion isn't suitable for actually creating that output.

 

Function takes one $argument in the form of the array you have there. It returns two pieces of information: an array with the parts of the title (ie, ["Sizes", "Colors", "Types"]) and an array of arrays containing the individual values.

0. If the $argument is empty then abort
1. If the $argument has one items then
  1. Make the sole item in the $argument be the $current array
  2. Make $title and $values both empty arrays
 Else it has more than one item so
  1. Pop off the first one as the $current array
  2. Call the function recursively with what is left
  3. Grab the $title and $values the function returned
2. Put the $current title at the beginning of the $title array
3. Set up a $new empty array
4. Loop through each $child in the $current array
  1. Loop through each $value in the array of $values
    1. Since $value is just a copy, put $child at the beginning of it
    2. Add the entire modified $value to the $new array
5. Return the $new array

To print it out,

1. Grab the $title and $values array that the function returned
2. Because there is no comma before the & you need some special treatment to display the $title properly:
  1. If there is one item then
    1. Display it as is
   Else if there are two items then
    1. Display them as "First & Second"
   Else there are more than two items so [*]
    1. Display everything except the last two items in the array as "Item, "
    2. Display the second-to-last item as "Item & "
    3. Display the last item
3. Loop through each $value in the $values array
  1. Display each item in $value as "[item]" with spaces between them [**]

* array_slice and implode may be handy here

** implode() will make this much easier

You don't happen to get these values from a database, or similar, are you?

The array generate from databases. It's dynamic values.

Great step and I'll try to figure it out

what?

[Christian F.]

Since you're fetching the values from the database, you should combine (JOIN) them i the query. No need to go about it the hard, and long way, of manually duplicating basic SQL logic.

Nesty looks like will make more queries to the DB.

 

http://codepad.org/6OFkbWoc example I have done with manually loops. I'm a bit blur to make recursive function to the depth.

[Christian F.]

Nope, you actually only need one query to fetch all of the information you want. That's why I mentioned JOINs.

 

Then you can build all three option lists with the same loop.
