How to access array values outside for loop in PHP

I'm working with array in PHP. My question is how to access PHP array values outside the for loop.

Here is the code.

<?php
$a = array("1","2");
for($i=0;$i<count($a);$i++){
#some core functionality DB related.
$val = $row['values'];
$b = explode(',',$val);
}
print_r($b);

$fin = array_combine($a,$b);
print_r($fin);
?>

I want to combine both the array, but I'm not getting array b. How to access the array values outside for loop?

Expected output:

Array ( [0] => 7 [1] => 6 ) // b array
Array ( [1] => 7 [2] => 6 ) // fin array

Try appending all the results to the original array. Something like this.

<?php
$a = array("1","2");

for($i=0;$i<count($a);$i++){
#some core functionality DB related.
$val = $row['values'];
$temp_array = explode(',',$val);
    for($j=0;$j<sizeof($temp_array);$j++){
        array_push($a,$temp_array[$j]);
    }
}
print_r($a);

?>

If I'm not wrong you are looking for this code with above what I have discussed with you

<?php
$a = array("1","2");
$b = array();
for($i=0;$i<count($a);$i++){
#some core functionality DB related.
$b[] = $row['values'];
}
print_r($b);

$fin = array_combine($a,$b);
print_r($fin);

?>

I keep staring at the original process and it seems unnecessarily convoluted. Does this not do what you wish:

$a=["1","2"];
foreach($a as $k=>$v){
    // I don't know if you are using $k or $v in your DB actions
    // On 1st iteration, $k=0 & $v="1"; on 2nd: $k=1 & $v="2"
    $fin[$v]=explode(',',$row['values']);
}
var_export($fin);

If this is wrong please let me know how it is wrong so I can better understand the question.
