PHP - Array result - php

Question

I have a big problem with a array and I want to group by key (or I don't now :( )
I get the links from mySQL and I do the following:
$lien2 = $links2['text'];
$lien2 = stripslashes($lien2);
$lien2 = htmlspecialchars($lien2);
$lien2 = nl2br($lien2);
preg_match_all('#http://.*?\.?([a-zA-Z0-9\-]+)(\.[a-zA-Z0-9]+)/[a-zA-Z0-9\/\*\-\?\&\%\=\,\.\;\#\_]+#i', $lien2, $lien2_result, PREG_SET_ORDER);
This is the array $lien2_result:
Array
(
[0] => Array
(
[0] => links1
[1] => A
)
[1] => Array
(
[0] => links2
[1] => B
)
)
Array
(
[0] => Array
(
[0] => links3
[1] => C
)
)
Array
(
[0] => Array
(
[0] => links4
[1] => B
)
)
Array
(
[0] => Array
(
[0] => links5
[1] => D
)
)
Array
(
[0] => Array
(
[0] => links6
[1] => E
)
)
and I want to get the following result:
A
links1
B
links2
links4
C
links3
D
links5
E
links6

I would adjust the query personally but if you are stuck with this resultset you could rewrite it with
foreach($lien2_result as $lien2){
foreach($lien2 as $item){
$arr[$item[1]][] = $item[0];
}
}
where print_r($arr) would result something like:
$arr = Array('A' => Array('links1'), 'B' => Array('links2','links4')); //and so on..
And actual printing the way you asked:
foreach($arr as $name => $value){
echo($name.'<br />');
foreach($value as $item){
echo($item.'<br />');
}
}
