doing filemtime after fopen / fwrite / fclose

Say I have the following script:

$timestamp = filemtime("test.txt");
echo 'original file time
'.$timestamp.'
';

$fp = fopen("test.txt",'w');
fputs($fp,$data);
fclose($fp);

$timestamp = filemtime("test.txt");
echo 'new file time
'.$timestamp.'
';
echo 'current time
'.time();
?>

When I run it, once, I get this as the output:

original file time
1188864270
new file time
1188864270
current time
1188864484

When I run it again, I get this as the output:

original file time
1188864484
new file time
1188864484
current time
1188864999

Basically, the combination of fopen / fwrite / fclose changes the file
modification time, as evidenced by the second execution of the PHP
script. filemtime, however, does not catch the updated file
modificatoin time when it's ran in the same script.

Any ideas as to why?
