Hi Ash, Actually I need the if because the code will print out an empty line and add "sometext" to it. So without the if check for an empty line, at the end of the loop I'll get sometext. For example, if the file I am processing called somename.txt has a b c in it. I'll have; asometext bsometext csometext but w/o the if check, I'll also have sometext as well.

Hi Shawn, Your code looks cleaner then mine so i tried it and got the last entry in the txt file printed twice. On Nov 30, 2009, at 7:07 AM, Shawn McKenzie wrote:

So here is my final test code, notice the check for ' ' in the if. Since I'm on Linux, this has to do with whats between the last
LF and
EOF which is nothing but this nothing will get printed out. $file = fopen("somefile.txt", "r"); while (! feof($file)) {
     $tmp = trim(fgets($file));
     if ($tmp != '')
{
$names = $tmp;
}
print $names."sometext\n"; } fclose($file);

Remove the if statement and just print out $tmp. The while loop is going over one extra time than you need, and on that final iteration, $tmp is an empty string. The if statement only changes $name if $tmp is empty, so it leaves it as it was, hence you getting the last line printed twice. Printing out an empty string in this example won't do anything, and the if statement is also pretty useless as it just copies the value to another variable on a condition that will only result in the side-effect you've noticed.
