Could be neater as:

while (list($key, $value) = each($line))
{
if (strtolower($value) == strtolower($line_to_delete))
{
unset($line[$key]);
break;
}
}

or even:

foreach ($line as $key=>$value)
{
if (strcasecmp($value, $line_to_delete)==0)
{
unset($line[$key])
break;
}
}

However, I think what you actually want might be:

foreach ($line as $linenumber=>$value)
{
if ($line_to_delete==$linenumber)
{
unset($line[$linenumber])
break;
}
}
