array filtering

hi
I have a string like this:

[code=php]$mystr= “1|26 1|68 1|62 3|2647 3|3010 2|3390 2|3544 1|4201 “;[/code]

I used explode function to have an array of that string:

[code=php]
$mystr= “1|26 1|68 1|62 3|2647 3|3010 2|3390 2|3544 1|4201 “;

$myarray = explode(‘ ‘, trim($mystr));
[/code]

now I have an array like this:

[CODE]0=>1|26
1=>1|68
2=>1|62
3=>3|2647
4=>3|3010
5=>2|3390
6=>2|3544
7=>1|4201
[/CODE]

now again I want to change this array to 3 smaller array (one for 1| one for 2| and one for 3|) someting like this:

[CODE]
array 1:
0=>26
1=>68
2=>62
3=>4201

array 2:
0=>3390
1=>3544

array 3:
0=>2647
1=>3010
[/CODE]

how can I do that?
thanks in advance
