simple bubblesort that doesn't work.

[Anon]

A newbie question:
I have made a simple bubblesort algorithm to sort an array with time stamps. But I can't get it working, it looks like it goes into a never ending loop.

This is the entire function:

function generate_sorted_entry_array($entries,$timestamps)
{
for ($i = 0; $i < count($entries)-1; $i++)
{
$helparray[] = $i;
}

$arraychanged = 1;
$forbool = 0;

while ($arraychanged)
{
$arraychanged = 0;

$forbool = 0;
//The problem seems to be in this loop.
for ($c = 0; $c < count($timestamps)-2; $c++)
{

  if ($timestamps[$c] > $timestamps[$c+1])
  {
    $temptime = $timestamp[$c];
    $timestamp[$c] = $timestamp[$c+1];
    $timestamp[$c+1] = $temptime;
    $temphelp = $helparray[$c];
    $helparray[$c] = $helparray[$c+1];
    $helparray[$c+1] = $temphelp;
    $forbool = 1;
  }
}
$arraychanged = $forbool;

}

for ($i = 0; $i < count($helparray)-1; i++)
{
$index = $helparray[$i];
$resultarray[] = $entries[$index];
}

return $resultarray;

I've probably overlooked something.

Thank you for your help.
