how to get single result from nested foreach - php

Question

I have a problem I've been trying to solve for two weeks now, please I need help on this. I do not understand using array well so please bear with me.
I'm trying to combine two arrays and store them in one array so I did this.
$oldvalue =$_SESSION[oldmids]; //value example aa=1,bb=2,cc=3;
$newvalue =$_SESSION[newmids]; //value example 001,002,003;
$result =array();
foreach($oldvalue as $oldval){
$kk =explode('=',$oldval);//i want to keep my tagging so
$oldtag =$kk[0]; // I use explode.
foreach($newvalue as $newid){
$kk =$oldtag.$newid;
$result[] =$kk;
}
}
// print_r($result);
my goal here is to keep my old tag and replace with numeric value, I don't have a problem with
the output, but I only need to get a unique value from my array $result. I tried using array_unique, but failed. Is this the right approach?

I'm not exactly sure what you are trying to do, but I think that array_push() is what you want:
http://www.php.net/array_push
This is my best guess:
$oldvalue =$_SESSION[oldmids]; //value example aa=1,bb=2,cc=3;
$newvalue =$_SESSION[newmids]; //value example 001,002,003;
$result = array();
foreach($oldvalue as $oldval){
$kk =explode('=',$oldval);//i want to keep my tagging so
$oldtag =$kk[0]; // i use explode.
foreach($newvalue as $newid){
$kk =$oldtag.$newid;
array_push($result, $kk);
}
}
print_r($result);
