Question

I have 2 arrays. 1 with items that should always be used and 1 with optional items.
What I want is a list of all possible combinations with these items.
The items in the array have to become attributes with a true or false value.

For example, the arrays

$requiredAttr = array('header', 'footer');
$optAttr = array('image');

Should give the following result:

header="false" footer="false"
header="false" footer="false" image="false"
header="false" footer="false" image="true"
header="true" footer="false"
header="true" footer="false" image="false"
header="true" footer="false" image="true"
header="false" footer="true"
header="false" footer="true" image="false"
header="false" footer="true" image="true"
header="true" footer="true"
header="true" footer="true" image="false"
header="true" footer="true" image="true"

Ofcourse this has the work with any number of items in both arrays.

<?php

$requiredAttr = array('header', 'footer');
$boolarr = array('true', 'false');
$optAttr = array('image' );

$larr  = combine_array($requiredAttr , $boolarr , '=');

$a_arr = array_slice($larr , 0 , count($larr)/2);
$b_arr = array_slice($larr , count($larr)/2 , count($larr)/2);


$larr_1    = combine_array($a_arr , $b_arr , ' ');
$larr     = combine_array($optAttr , $boolarr , '=');
array_push($larr , ''); // for optional

$larr_3  = combine_array($larr_1 , $larr , ' ');

function combine_array($first_arr , $second_arr , $separator)
{
    $combine_arr  = array();
    for($i=0;$i<count($first_arr) ; $i++)
    {
    for($j=0;$j<count($second_arr) ; $j++)
    {
        array_push($combine_arr , $first_arr[$i].$separator.$second_arr[$j]);
    } 
    }
    return $combine_arr;
}



print_r($larr_3);
