you cannot prepend to a file. to do that you need to create a new
file, write the new data in it, and append data from the old file.
class newLiner extends IteratorIterator
{
function current()
{
return $this->getInnerIterator()->current() . "\n";
}
}
$lines = array('line 1', 'line 2', 'line 3');
$data = new newLiner(new ArrayObject($lines));
$file = new SPLFileObject('file', 'r');
$temp = new SPLFileObject('temp', 'w');
$all = new AppendIterator;
$all->append($data);
$all->append($file);
foreach ($all as $line) {
$temp->fwrite($line);
}
$file->fflush();
$temp->fflush();
unset($file); unset($temp);
