Problem
My code:
$i = 0;
$file = fopen('ids.txt', 'w');
foreach ($gemList as $gem)
{
fwrite($file, $gem->getAttribute('id') . '\n');
$gemIDs[$i] = $gem->getAttribute('id');
$i++;
}
fclose($file);
It’s writing n as a string for some reason, so the file looks like this:
40119\n40122\n40120\n42155\n36925\n45881\n42145\n45880
According to Google, I should use rn, but r is a carriage return, which isn’t what I want to accomplish. All I need is for the file to look like this:
40119
40122
40120
42155
36925
45881
42145
45880
Thanks.

‘n’ should be replaced with “n.” When you use ‘, the escape sequence is not recognized.
See the manual.
See this note for information on how to write line endings. In general, different operating systems have different line-ending conventions. “rn” is used by Windows, while “n” is used by Unix-based operating systems. Stick to one naming scheme (I’d go with “n”) and open your file in binary mode (fopen should get “wb”, not “w”).

Use PHP EOL, which produces rn or n depending on the operating system.

Since PHP 4.3.10 and PHP 5.0.2, PHP EOL has been a predefined constant. See the following manual posting:
This will save you time and effort when developing cross-platform applications.
IE.
$data = 'some data'.PHP_EOL;
$fp = fopen('somefile', 'a');
fwrite($fp, $data);
If you looped this twice, you’d get the following in’somefile’:
some data
some data

You can also use file put contents() to get the contents of a file:
file_put_contents('ids.txt', implode("\n", $gemList) . "\n", FILE_APPEND);
