php multidimensional array, implode twice? - php

Question

I need some help trying to implode my multidimensional array twice. I'm using Joomla 2.5 and it's for a backend component..
Here's what the array is:
Array
(
[jform] => Array
(
[options] => Array
(
[colour] => Array
(
[0] => a
[1] => d
)
[size] => Array
(
[0] => b
[1] => e
)
[qty] => Array
(
[0] => c
[1] => f
)
)
)
)
I've tried using the following code:
$i=0;
$optchildArr = array();
$optchildArrX = array();
foreach ($this->options as $optArr) :
$j=0;
foreach ($optArr as $arr) :
$optchildArrX[] = $arr;
$j++;
endforeach;
$optchildArr[$i] = implode(',',$optchildArrX);
$i++;
endforeach;
$this->options = implode(';',$optchildArr);
But I'm getting these kind of results:
[options] => Array
(
[0] => a,d
[1] => a,d,b,e
[2] => a,d,b,e,c,f
)
When I'm after:
[options] => Array
(
[0] => a,b,c
[1] => d,e,f
)
Any help would be greatly appreciated!! :)

Answer 1

Assuming the main array is $A
function mergeArrays($colour, $size, $qty) {
$result = array();
for ($i=0; $i<count($colour); $i++) {
//Assuming three arrays have the same length;
$result[] = implode(',',array($colour[$i], $size[$i], $qty[$i]));
}
return $result;
}
$result_array = array_map(
'mergeArrays',
$A['jform']['options']['colour'],
$A['jform']['options']['size'],
$A['jform']['options']['qty']
);
//Check the output from this, should be the output you described.
var_dump($result_array);
