Array in Powershell - Cant read each value by corresponding with a second array

Question

I'm working on a project,

I have 3 arrays, and i want to take all values from it. maybe some code would be better than explanation.

$Array1= "Value1", "Value2", ....
$Array2= "Another1", "Another2",...
$Array3= "Again1", "Again2", ...

My result should be

Value1 Another1 Again1
Value2 Another2 Again2

etc...

I've tried many option like so :

foreach($i in $Array1){
  Foreach($j in $Value2){
     Write-host $i "," $j
   }
} 

result:
Value1, Another1
Value1,Another2
Value2,Another1
Value2,Another2

I've search a solution for like 5 hours . and i'm not an expert in powershell. please help me !!

You need to make sure either all arrays have the same number of elements, or take the minimum amount of elements to loop through:

$Array1= "Value1", "Value2" #
$Array2= "Another1", "Another2"#
$Array3= "Again1", "Again2"#

# make sure you do not step out of index on one of the arrays
$items = [math]::Min($Array1.Count, [math]::Min($Array2.Count, $Array3.Count))

for ($i = 0; $i -lt $items; $i++) {
    # using the -f Format operator gives nice-looking code I think
    '{0},{1},{2}' -f $Array1[$i], $Array2[$i], $Array3[$i]
}

Result:

Value1,Another1,Again1
Value2,Another2,Again2
