space caused by new line break

If I use the file() command to read lines of a file, each line is returned by the line break function attached. This is causing me a problem with something like this

$stuff = file("./somefile.data");

while (n < 50)
{
$details = file("./$stuff($n).data");
$n++;
}

because $stuff has a line break after it and the file cannot be read to details[]
ie it tries to read filecontents .data rather than filecontents.data so an error occurs reading the file

how can I stop this?

you have to trim() the line first in order to strip off the trailing \n.

while($n < 50) // you forgot the $ here
{
$stuff[$n] = trim($stuff[$n]);

the next line should be:
$details = file('./'.$stuff[$n].'.data');

generally I would suggest:

$stuff = file("./somefile.data");

for($i=0; $i<count($stuff); $i++)
{
$details = file('./'.trim($stuff[$n]).'.data');
// do something with $details ...
}
