exploding textarea values into multiple array

Question

Exploding textarea value like this:

explode("\n", $input);

would result in one array.

Currently, I am storing $input in textarea like this:

a1
a2
a3

b1
b2
b3

c1
c2
c3

But I want to get multiple array which would result like this:

$test[0][0] = 'a1';
$test[0][1] = 'a2';
$test[0][2] = 'a3';

$test[1][0] = 'b1';
$test[1][1] = 'b2';
$test[1][2] = 'b3';

$test[2][0] = 'c1';
$test[2][1] = 'c2';
$test[2][2] = 'c3';

Any idea, how can I implement?

What's the input? Based on what rule do you expect to construct that result? — deceze

In what format? is it a1,a2,a3\nb1,b2,b3\nc1,c2,c3 for example? — Ben Swinburne

Explode by two newlines to separate your groups, explode each group by a single newline:

$result = array_map(
    function ($group) { return explode("\n", $group); },
    explode("\n\n", $input)
);

amazed:) I'm getting like this: Array ([0] => Array ([0] => a [1] => b [2] => c [3] => [4] => d [5] => e [6] => f [7] => [8] => g [9] => h [10] => i ) )

Then your input is actually different. Are newlines \r\n perhaps...?

Any other idea? I would be glad if I can separate them by a group name in textarea like: group1 a1 a2 a3 group2 b1 b2 b3 etc. each are in new line.

Lot's of possible ways to skin this cat. a1,a2,a3 \n b1,b2,..., or whatever other format you can come up with. What's the easiest to write for the people needing to input this date...?!

Yeah agree. Just wanted to know using group name.

Something like this should work dont know if there is anicer way

$exploded_values = explode("\n", $input);

$i = 0;
$amount_of_exlodes = 0;

foreach($explodes_values as $exploded_value){
 $test[$i][] = $exploded_value;
 $amount_of_explodes ++;
 if($amount_of_explodes >= 3){
  $amount_of_explodes = 0;
  $i++;
 }

}

Well he wants a new array inside an array every 3 times right.. This might work I ahvent tested it but hey.. And it probably isnt the nicest code but it wil work.

"he wants a new array inside an array every 3 times right" – that's exactly what we don't know here... Could be some completely different logic.

According to his example I think thats what he wants, then this works otherwise he should make himself more clear. im trying to help as much people to actually get some reputation so i have more priviliges
