RE: [users@httpd] Delete Blank Lines In A Text File

[Wagner, Aaron]

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.

Subject: [EMAIL PROTECTED] 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
