Need help writing ping results to separate files for up and down machines

I need to ping a list of machines and have the results split between up and down into two different .txt files.

$PingPCs = Get-Content "C:\Temp\Cache Cleanup Project\Computerlist.txt
foreach ($PC in $PingPCs) {
        $up = Test-Connection $PC -Count 1 -Quiet
        if($up) {
                  $Response = Test-Connection $PC -Count 1 | Select-Object Name
                  $Response ## Need help figuring out the outfile process to write to .txt ##
        }
        else {
              $Failed = "$PC is not reachable"
              $Failed ### Need help figuring out the outfile process to write to .txt ###
        }
}

The two places I need help with is just writing the results to separate text files. One file named Online.txt and the other Offline.txt.

You can do something like this, instead of exporting the results on each iteration and appending to a file, it's a better idea to first perform your test and save the results in memory. Once all is complete, export the results:

$PingPCs = Get-Content "C:\Temp\Cache Cleanup Project\Computerlist.txt"

$result = foreach ($PC in $PingPCs)
{
    $testConnection = Test-Connection $PC -Count 1 -Quiet

    [pscustomobject]@{
        ComputerName = $PC
        TestConnection = $testConnection
    }
}

$result.where({$_.TestConnection}) | Out-File "x:\path\to\online.txt"
$result.where({-not $_.TestConnection}) | Out-File "x:\path\to\offline.txt"

Edit

Adding nice optimization to export the results. Thanks @mklement0

$online, $offline = $result.where({$_.TestConnection},'Split')
$online | Out-File "x:\path\to\online.txt"
$offline | Out-File "x:\path\to\offline.txt"
