How can I avoid a full blank line while reading information from a text file.
Im going to parse this text and insert the information into a database however there are some blank lines and these get me in trouble because Im parsing the text using explode and Im parsing it according to the rn at first.So it gets the blank lines as well.But It mustnt get.
anyone helps??

@aaronbdavisMar 07.2006 — read the entire file into a variable. The do a preg_replace on successive occurances of newline.

[code=php]$subject = file_get_contents($file_name);
$newline = "rn";
$replace = "";
$pattern = "/$newline(s)*$newline/";
$subject = preg_replace($pattern,$replace,$subject);
$subject_array = explode($newline, $subject)[/code]

I haven't tested this but i think it will work.
