Interesting Actually, I use the file() function to read the whole file into an array, so the file isn't open when you do the fopen() of the output file. That's how you can write to the same filename, at least on OS's that don't do file versions. On OS's with file versions, like VMS, opening the same file name just creates a new version and the old file remains intact.

If the file gets big, he could take a performance hit skipping multiple lines. If you ran the script you would see that the output file doesn't have the blank lines.

That's nice but it doesn't fix the blank lines it just skips them in the
file parse. I think he wants to clean the file. If the file gets big,
he could take a performance hit skipping multiple lines.

RE: [EMAIL PROTECTED] Delete Blank Lines In A Text File
preg_replace($pattern, $replacement,
$string);
preg_replace("/\n\r *\n\r/","\n\r",
$string )
\n\r *\n\r - for a windowz maching and they may be in
the wrong order.
Your basically replacing all double linefeeds with a
single linefeed.
Replace the \n\r with whatever your OS uses as a
linefeed.

Delete Blank Lines In A Text File
Does anyone know how to use PHP to delete blank lines in a text file. I
use a text file to store usernames and passwords but with adding and deleting
users, blank lines appear which returns an undefined offset error when the
'verify user script' tries to read each line of the text file.
Thanks
